Building GDB 7.3.92 with MinGW

Building GDB 7.3.92 with MinGW

[Eli Zaretskii]

I've successfully built the latest pretest of GDB 7.3.92 with MinGW on
MS-Windows.  But I did encounter a few minor issues; this is my report
about them.

1. Compilation warning:

     gcc -O2 -gdwarf-2 -g3 -D__USE_MINGW_ACCESS   -I. -I. -I./common -I./config -DLOCALEDIR="\"/d/usr/share/locale\"" -DHAVE_CONFIG_H -I./../include/opcode -I./../opcodes/.. -I./../readline/.. -I../bfd -I./../bfd -I./../include -I../libdecnumber -I./../libdecnumber -I./../intl -I./gnulib -Ignulib    -I/d/usr/include -Id:/usr/Python26/include -Id:/usr/Python26/include -Wall -Wdeclaration-after-statement -Wpointer-arith -Wformat-nonliteral -Wno-unused -Wunused-value -Wunused-function -Wno-switch -Wno-char-subscripts -Wno-format  -c -o utils.o -MT utils.o -MMD -MP -MF .deps/utils.Tpo utils.c

  Any objections to the following patch?  (If approved, I will add a
  comment explaining the problem on Windows which requires this.)

2. "make install-strip" fails in readline/, in sim/, and in gdb/:

     make[2]: Entering directory `/d/usr/eli/utils/gdb-7.3.92/readline'
     make[2]: *** No rule to make target `install-strip'.  Stop.

     make[1]: Leaving directory `/d/usr/eli/utils/gdb-7.3.92'
     make: *** [install-strip] Error 2

   The reason is that these directories simply don't have the
   "install-strip" target in their Makefile.in files.  I think that
   target should be added, because that's AFAIK how GDB is supposed to
   be installed on end-user systems.

3. Manuals are (unexpectedly) regenerated as part of "make":

     make[4]: Entering directory `/d/usr/eli/utils/gdb-7.3.92/gdb'
     make[5]: Entering directory `/d/usr/eli/utils/gdb-7.3.92/gdb/doc'
     (test "cp -p" = "ln -s" && \
	       ln -s ./all-cfg.texi gdb-cfg.texi) || \
	     ln ./all-cfg.texi gdb-cfg.texi || \
	     cp ./all-cfg.texi gdb-cfg.texi
     echo "@set GDBVN `sed q ./../version.in`" > ./GDBvn.new
     if [ -n "(GDB) " ]; then \
	       echo "@set VERSION_PACKAGE (GDB) " >> ./GDBvn.new; \
	     fi
     echo "@set BUGURL @uref{http://www.gnu.org/software/gdb/bugs/}" >> ./GDBvn.new
     if [ "@uref{http://www.gnu.org/software/gdb/bugs/}" = "@uref{http://www.gnu.org/software/gdb/bugs/}" ]; then \
	       echo "@set BUGURL_DEFAULT" >> ./GDBvn.new; \
	     fi
     if test -z "-I ./../../readline/doc"; then \
	       echo "@set SYSTEM_READLINE" >> ./GDBvn.new; \
	     fi
     mv GDBvn.new GDBvn.texi
     makeinfo --split-size=5000000 --split-size=5000000 --split-size=5000000 -DHAVE_MAKEINFO_CLICK -I ./../../readline/doc -I ./../mi -I . \
		     -o gdb.info ./gdb.texinfo
     makeinfo --split-size=5000000 --split-size=5000000 --split-size=5000000 -DHAVE_MAKEINFO_CLICK -I . -o gdbint.info ./gdbint.texinfo
     makeinfo --split-size=5000000 --split-size=5000000 --split-size=5000000 -DHAVE_MAKEINFO_CLICK -I . -o annotate.info ./annotate.texinfo

   The reason is that gdb-cfg.texi and GDBvn.texi are not in the
   tarball, but they are build dependencies of the manuals:

     GDB_DOC_BUILD_INCLUDES = \
	     gdb-cfg.texi \
	     GDBvn.texi
     GDB_DOC_FILES = \
	     $(srcdir)/gdb.texinfo \
	     $(GDB_DOC_SOURCE_INCLUDES) \
	     $(GDB_DOC_BUILD_INCLUDES)
     ...
     # GDB MANUAL: info file
     gdb.info: ${GDB_DOC_FILES}
	     $(MAKEINFO_CMD) $(READLINE_TEXI_INCFLAG) -I ${GDBMI_DIR} -I $(srcdir) \
		     -o gdb.info $(srcdir)/gdb.texinfo

   I think these two files should be added to the distribution, since
   end users should not be required to have Texinfo installed to build
   GDB.

Finally, a question: Why are we installing libraries (libbfd,
libopcodes, libiberty) and the standards.info manual?  The libraries
are not part of GDB, we import them from elsewhere.  "make install"
will happily overwrite existing installation of these libraries that
could potentially be newer, coming from their respective upstream
distributions.  How about removing these from "make install"?

As for standards.info, if we decide to keep distributing it (which I
don't think we should), we should at least make a point of having the
latest version in our tarballs; the one in 7.3.92 isn't.

This is ok with me but remove the "&& defined(MOUSE_MOVED)".
And one space after defined in "defined(__MINGW32__)".

Sounds reasonable, but something to leave for 7.5?

Sounds reasonable to me, but it seems odd.
Why hasn't this come up before?
[Users are indeed not required to have texinfo.]

I don't have an opinion on this.
A counter argument could be that someone may already be expecting them
to be installed.

Minor preference for keeping it, I've gotten used to it being installed.

This is in the GNU standards, but in practice few people use it.

Of course, patches are welcome.  This isn't the only places where gdb's
Makefiles diverge from the standards.

For libiberty, gcc is the authoritative source.  So, ask there.

For the others, ask on the binutils list.

I tend to agree they should not be installed.

IMO we should remove this.  Actually, most of the things in src/etc seem
outdated or useless or somebody else's code.

I'm not sure who owns this directory, you should ask on binutils before
taking any action.

      The reason is that these directories simply don't have the
      "install-strip" target in their Makefile.in files.  I think that
      target should be added, because that's AFAIK how GDB is supposed
      to be installed on end-user systems.

`make install' is generally the way one should install GNU projects on
a end-user system, since that makes it possible to debug things (hence
why CFLAGS contains -g by default); install-strip is really for people
with little disk space.

   Finally, a question: Why are we installing libraries (libbfd,
   libopcodes, libiberty) and the standards.info manual?  The
   libraries are not part of GDB, we import them from elsewhere.
   "make install" will happily overwrite existing installation of
   these libraries that could potentially be newer, coming from their

   "make install"?

I personally never understood why they get installed by binutils, or
gdb.

My view is that libiberty should not be installed (unless 
--enable-install-libiberty or --enable-install-libbfd).  (These options 
already exist; it's just some defaults that are installing too much; maybe 
in some cases the options only control the headers not the libraries.)

I have no idea.  Maybe it's some remnant from the times, not so long
ago, when manuals weren't produced unless you said "make info".

You can always get it from its origin, which is here:

Unlikely: it's the problem between PDCurses and the MS-Windows API
header files.

Well, an unstripped GDB weighs in at some 47MB, which is just too
much.

And you can't usefully debug it outside of the source tree anyway.

I normally keep the unstripped binary with the sources, but install
stripped ones.

Well, having the sources is useful of course :-), but for reference
sake there is value in debugging gdb outside of the *build* tree.
i.e. debugging the installed copy.
gdb is now more dependent on ancillary files (python, etc.) and it's
useful to run gdb the way users run it.
For one, remembering to pass -data-directory is a pain. :-)

This parameter does not work correctly under MinGW in the case that I would like gdb to automatically run the python script when it startup.

Normally, my gdb is put in MinGW/bin, and the gdb's own python script is under:
MinGW\share\gdb\python\gdb\*.py

I need to hard-code the code in gdb/main.c to set the data-directory value. (Because gdb is build from MSYS+MinGW, but it run normally on Windows shell without MSYS)

Here are some hard-code modify to the main.c file, if you do not change this, there is no way to load gdb's own python scripts.

Yeah, this is a better way, I found install-strip does not work under mingw for a long time.
Here is what I did before:
make install
cd to installed_folder
strp *.exe

I keep the unstripped binary in the build tree, because I can debug it under MinGW, I'm not sure I can do this if I move the stripped version to some other place, maybe I need to adjust the source path.

We could side-step these issues by documenting in the README that
GDB should be installed using "make -C gdb install", or "make -C
gdb install-strip". This is what I personally do.

That doesn't strip the libraries, and if GDB will some time distribute
a shared library, won't DTRT with them.

Stripping libraries needs special switches to `strip' which is a pain
to type, and for *.a libraries you need to run ranlib afterwards.
"install-strip" does all that automatically.

Thank you very much!

Mostly I think I don't need the "include" and "lib" folder in gdb.
Do I need to develop a program depend on gdb's library? No
I only need "bin" and "shared" folder.

Hi, I was originally open a discussion on the Codeblocks' forum

http://forums.codeblocks.org/index.php/topic,15104.0.html

The major problem is:

gdb/main.c (setting the gdb's python folder) execute before we use data-directory to set the python path, so whether you set -data-directory, you always failed to find its own python script.

You can check my patch and see what I adjust the path, so gdb can find and run its own python script correctly.

This issue is that MSYS+autoconf system use different path scheme with normal mingw. But when you run gdb under normal mingw, you still have some internal variables which is MSYS style.

When you say "run the python script", *which* python script are you
referring to?

*If* there is a bug here, and it's not pilot error, it feels like
perhaps the bug is in relocate_gdb_directory.
[Why don't all calls to relocate_gdb_directory require similar treatment?
Thus this feels like the wrong way to go.]

Maybe if you provide a sample session (and complete session please, no
editing to trim it down), that will help.

I have just look at my notes half years ago(no time to write a complete session right now), the issue is:
In the file:

build\gdb\config.status

The value is hard-coded:

D["DEBUGDIR"]=" \"/mingw/lib/debug\""
D["DEBUGDIR_RELOCATABLE"]=" 1"
D["GDB_DATADIR"]=" \"/mingw/share/gdb\""

There are some code snippet:

gdb_program_name = xstrdup (argv[0]);

  if (! getcwd (gdb_dirbuf, sizeof (gdb_dirbuf)))
     /* Don't use *_filtered or warning() (which relies on
       current_target) until after initialize_all_files().  */
     fprintf_unfiltered (gdb_stderr,
            _("%s: warning: error finding "
              "working directory: %s\n"),
                        argv[0], safe_strerror (errno));

  current_directory = gdb_dirbuf;

  /* Set the sysroot path.  */
  gdb_sysroot = relocate_gdb_directory (TARGET_SYSTEM_ROOT,
                    TARGET_SYSTEM_ROOT_RELOCATABLE);

  debug_file_directory = relocate_gdb_directory (DEBUGDIR,
                         DEBUGDIR_RELOCATABLE);

  gdb_datadir = relocate_gdb_directory (GDB_DATADIR,
                    GDB_DATADIR_RELOCATABLE);

But those values were not set correctly, so I need to hack the path under MinGW.

It is quite simple to test whether GDB set the python path correctly, just run:

python print gdb.PYTHONDIR

If it shows the correct path, then it's good.

PS: I will have a travel in two days, so further response from me will be some bit later.

This is not hard-coded, this comes from the --prefix argument you
passed to the configure script.  In my config.status it shows the
correct directory.

There's a problem loosely related to the MinGW build, whereby it is
customary on MS-Windows to move the built binaries to another machine,
e.g. if one downloads pre-built binaries from some site, like the
MinGW site.  If the --prefix value used by whoever built the package
does not fit the end-user's filesystem and/or the top-level directory
under which the binary distro is unpacked, then things will not work.

So I think in the long run it would be a Good Thing for GDB to try to
look for its data files relative to the place where the executable is
installed, and not only on Windows.  But that is a separate project;
at least I would love to see patches along these lines.

The above works correctly for me in the GDB I just built with MinGW.

I think we already, unless I misunderstood what you are trying to say.
Every night, we build GDB on one Windows machine and then test it on
all other Windows machines we have, using a different install prefix.
GDB seems to be able to find all auxilary files without problem.

The only case when path "relocation" is turned off is when the user
configured directories such as the gdb-datadir using a path that is
not a subdir of the prefix.

That latter case is what I had in mind.  In general, it is a bad mojo
to force Windows users to install binaries in some specific tree or
under a certain parent directory.  E.g., the binary could be
configured for d:/usr as a prefix, but installed in c:/foo/bar.

This is not what I meant, or did I misunderstand you.

Here is what I am trying to say. It is perfectly fine to do:

  % /path/to/gdb/configure --prefix=c:/usr/my-gdb
  % make
  % make install
  % cp -R c:/usr/my-gdb c:/foo/bar

Relocations should still be working, and our own experience with
that reveals no obvious problem.

What I am saying is the following configure command will turn
gdb-datadir relocation off:

  % /path/to/gdb/configure --prefix=c:/usr --with-gdbdatadir=c:/foo

This is because c:/foo is not "inside" c:/usr.  On other other hand,
datadir relocation would still be active if --with-gdbdatadir was
c:/usr/share/gdb-datadir.

Do we really want to preserve the alternate solution? We have more
and more support files that come with GDB, so it's less and less
likely to install a fully-functional GDB. (it is fine with me if
we want to preserve it, just wanted to mention it).

I agree; I was surprised to see that in README to begin with.  If no

I did exactly the same thing as Joel said, but NO luck here.
(I debugged this issue in August 2011 for several days)

1, I build gdb under MSYS+MinGW, and the configure command has the Linux style path like:

../gdb/configure --prefix=/c/user/my-gdb

gdb can not find the python automatically.

2, I just test the official mingw-gdb (with python enabled), gdb can't relocate the "shared" path either.

3, here is what I did to check whether it works:

a, suppose you have gdb install or copied in some folder:
c:/path_to_mingw/bin/gdb.exe
c:/path_to_mingw/share/gdb/python/gdb (this folder contains some python script like:printing.py....)

b, run the gdb.exe.
b1, you can type:
python print gdb.PYTHONDIR
It should return the windows path: c:/path_to_mingw/share/gdb/python

b2, you can continue type:
info pretty-printer
Then, gdb will report all the pretty-printers installed. If you encountered some error message like:
Undefined info command: "pretty-printer".  Try "help info".
This means gdb's own python script does not loaded correctly when gdb startup, this is because gdb can't find the path:
c:/path_to_mingw/share/gdb/python/gdb

So, Joel, can you just test the steps I described above? Both step a, and step b, b1, b2.

With my hacky patch I posted in this thread some days ago, my gdb.exe can works OK wherever the "path_to_mingw" put, so it is relocated.

What does it mean if "info pretty-printer" doesn't display anything,
but doesn't show any error messages, either?

I test it again today, and it does not works on my XP.
The official MinGW-gdb is build with such configure option(like my personal build):
           CFLAGS="-O2 -fno-omit-frame-pointer -mtune=i686" \
           ../gdb-7.3.1/configure \
           --program-suffix="-python27" \
           --prefix=/mingw \
           --host=mingw32 \
           --build=mingw32 \
           --target=mingw32 \
           --with-python=/python/python \
           --with-expat

When you put the MinGW in some different folders in the driver E:
like e:/mymingw1  and e:/mymingw2

When you run gdb and enter: python print gdb.PYTHONDIR, it will always return:
e:\mingw\share\gdb/python
You see, I have no such path here in dirver e.
I'm not sure how you test your gdb, did you just put you MinGW under e:/MinGW? Can you try some other places?

If you don't have any pretty-printers installed, but gdb's own python script loaded correctly.
you will have nothing returned from gdb, like:
(gdb) info pretty-printer [ENTER HERE]

Are you saying that the problem happens only if the directory
configured as --prefix does not exist at all on the machine where you
run GDB?

RE: Building GDB 7.3.92 with MinGW

[Pierre Muller]

  After some debugging,
I believe that the main problem is related to the fact
that we use msys environment (which has msys specific mounts)
to compile a mingw32 GDB executable that knows nothing about those msys
mount points!

 config.h 
get several entries with directories.
All but WITH_PYTHON_PATH (which is mingw32 compatible)
are msys paths:
 DEBUGDIR, GDB_DATADIR and JIT_READER_DIR
but those msys pathes are not interpreted correctly by
a mingw32 executable (i.e. gdb.exe itself).

  I do believe that this is an error in the mingw32 configuration
and that it should be fixed in those configuration files...

  As an example I tried to use --prefix=/e/pas/fpc-2.6.0
msys /e/ corresponds to e:/ in mingw32,
but 
(gdb) py print gdb.PYTHONDIR
e:\e\pas\fpc-2.6.0\share\gdb/python
Of course, this path doesn't even exist on my computer!
If I do substitute /e/ by e:/ inside config.h
and at least get an existing path as output of (gdb) py print gdb.PYTHONDIR

  The bad part is that msys doesn't have a
equivalent of cygpath utitlity, so that I proposed
a solution above, but I have no idea about how
to really implement that solution...

Hi, thank you very much for the testing, and I'm totally agree with you.

In my hacky patch, I use one Windows API function:
#ifdef _WIN32
int get_app_fullpath(char *location, int length)
{
     int len = GetModuleFileName(0, location, length);
     return len;
}
#endif

This, I get the path of the gdb.exe, then I adjust the path to get the "share" folder.

This might explain how it works for me: I manually edit config.h to
convert MSYS file names to native Windows ones, before building GDB.

Perhaps Joel could tell where and how the relocation of the standard
directories happens for him, and then we could try stepping through
that code with a debugger.

A simple Sed script will do, but it must be injected into the
configure script.

Alternatively, did you try to use MinGW file names in --prefix when
configuring in the first place?

This should not be necessary.

I am not too sure whether the problems with MSYS also happen on cygwin
or whether you have different issues. But I *think* we solve the problem
by using semi-absolute paths (a path that looks absolute in a Unix
environment, but is only missing the drive letter in the windows
environment). To make it work, we use a directory name that works
in both environments. For instance, if one could have directory c:/gnu/,
and setup cygwin to mount c:/gnu into /gnu.

And then, one could configure GDB with a prefix such as --prefix=/gnu.
As long as the other directories are configured as a subdirectory of
that prefix, it should work as well as it does for me.

I said "I think" because the environment was setup for me, and it just
worked, so I never looked into this further.

Naively, I thought that it would have worked anyways if GDB was
configured with an MSYS-only path. I just don't know enough about
the whole process to understand what happened without debugging
myself. I am wondering whether, maybe, the configure script is auto-
computing some paths that, textually, do not look like a subdirectory
of the prefix.

The relocation happens during startup. Search for "relocate" in
main.c (I think - it should be inside function "captured_main").

During your debugging, it would be good to know whether the relocation
is turned off, of whether it is failing.  A good way to figure this
out, is to look at the generated gdb/config.h file. Search for "RELOCAT",
and in particular: PYTHON_PATH_RELOCATABLE (I think that's what
matters). In fact, why don't you and Pierre send your gdb/config.h file
for us to inspect. Attached is mine.

That's what we do. I missed this part of your reply when I started
writing mine. The "trick" is to provide a directory name that both
MinGW and MSYS understand (I am not really sure why this is necessary).

RE: Building GDB 7.3.92 with MinGW

[Pierre Muller]

Eli,

  I also wrongly supposed that configure prefix or related entries should
be msys pathes.
  It seems that using directly a mingw32 path for prefix
works well. This allows to get a working relocate_gdb_directory
call in main.c
  Of course, this only works for really existing directories, but 
from what I read in the sources, this was by design.
  A configured directory should only be substituted if the substitute result
is an existing directory.
 
 So I used
  --prefix=e:/pas/fpc-2.6.0
to run configure
ran 'make all install'
and got a first installation in e:\pas\fpc-2.6.0
I then tried 
make install prefix=e:/pas/fpc-2.7.1/gdb
and debugged GDB with itself in e:\pas\fpc-2.7.1\gdb\bin
gdb ./gdb
added a break relocate_gdb_directory
and could check that
e:/pas/fpc-2.6.0/share/gdb
was transformed into 
e:\pas\fpc-2.7.1\gdb\share\gdb

  I also thought that msys system required
real msys pathes to function correctly, but it seems to handle
Mingw32 pathes starting with X:/ correctly also 
which solves the problem.
  I am still surprised that in fact, we really need to do
this in order to get the correct behavior.

  That not true in case you really have other mount points
I personally have my different GDB sources located inside cygwin
/usr/local/src
subdirectories, and I also have
 this cygwin /usr/local/src mounted as /usr/local/src on mysys,
which is nice in a way, but leads me to not be able to 
remember in with Windows directory the sources really are ...

As said above, it seems that this is the right answer!

If so, that's not what I was looking for.  I was looking for a way for
GDB to "auto-configure" its directories based on the directory where
gdb.exe lives.

Thanks for the pointers, I will have a look.  But from what's been
said here, I suspect that it "fails" by design.

If the configury supports d:/foo/bar file names (and most modern
versions of Autoconf and libtool do), then using MSYS /d/foo/bar style
of file names is not necessary.  Only of d:/foo fails, you should fall
back on the MSYS style.

Yes, sounds like that.  It would be good if GDB could reconfigure its
prefix on the fly, though.

  In fact, I think I have now finally found where the problem starts
if you do not specify any --prefix to configure:
  --prefix has a default /usr/local value,
this sets prefix inside gdb/Makefile
  and three directories inside config.h
$ grep 'DIR "' *.h
config.h:#define DEBUGDIR "/usr/local/lib/debug"
config.h:#define GDB_DATADIR "/usr/local/share/gdb"
config.h:#define JIT_READER_DIR "/usr/local/lib/gdb"

But what about BINDIR which is used for reloacate_gdb_directory..
This one is not inside config.h :

$ grep -n -C 3 BINDIR *
Makefile-1520-# Some files need explicit build rules (due to -Werror
problems) or due
Makefile-1521-# to sub-directory fun 'n' games.
Makefile-1522-
Makefile:1523:# main.o needs an explicit build rule to get
TARGET_SYSTEM_ROOT and BINDIR.
Makefile-1524-main.o: $(srcdir)/main.c
Makefile:1525:  $(COMPILE) $(TARGET_SYSTEM_ROOT_DEFINE)
-DBINDIR=\"$(bindir)\" $(srcdir)/main.c
Makefile-1526-  $(POSTCOMPILE)
Makefile-1527-
 
  OK, but defining a macro inside config.h or on command line should 
not make any difference, no?
  The following will prove otherwise!

For testing purpose, I tried to recompile main.o
adding --verbose option to compiler
$ make  main.o CFLAGS="-g -O0 --save-temps --verbose"

Did you see want happens?
  -DBINDIR="/usr/local/bin\"
gets transformed into '-D' 'BINDIR="E:/msys/mingw32/msys/1.0/local/bin"'
inside COLLECT_GCC_OPTIONS!

So that once this compiled gdb executable is put to e:\pas\fpc-2.7.1\gdb\bin
relocate_gdb_directory function doesn't find any
common part between E:/msys/mingw32/msys/1.0/local/bin
and /usr/local/share/gdb
which leads to failure in directory relocation.

  I think that moving BINDIR also into config.h
should fix that msys specific failure.
