TARGET undefined in bucomm.c

TARGET undefined in bucomm.c

[Luke]

I'm trying to compile binutils-2.21 on x86_64 .  I configured using:

$ mkdir build
$ cd build
$ ../configure --target=arm-none-eabi --enable-multilib --with-gnu-as
--with-gnu-ld --disable-nls --disable-werror

It gets through the compilation of libiterty, bfd, and opcodes.  Then,
when building binutils, it fails as follows:

gcc -DHAVE_CONFIG_H -I. -I../../binutils  -I. -I../../binutils
-I../bfd -I../../binutils/../bfd -I../../binutils/../include
-DLOCALEDIR="\"/usr/local/share/locale\""
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT bucomm.o
-MD -MP -MF .deps/bucomm.Tpo -c -o bucomm.o ../../binutils/bucomm.c
../../binutils/bucomm.c: In function ‘set_default_bfd_target’:
../../binutils/bucomm.c:160:24: error: ‘TARGET’ undeclared (first use
in this function)
../../binutils/bucomm.c:160:24: note: each undeclared identifier is
reported only once for each function it appears in

I have grepped all the files for TARGET and don't understand why this
would be happening -- am I using configure wrong, or do I need to
define an environment variable?

I have filed a bug report here:
http://sourceware.org/bugzilla/show_bug.cgi?id=12844

Searching the internet has been fruitless, has anybody else seen this behavior?

Let me know if there is other information I should provide to help
figure this out.

Thanks,

~Luke

Please show

# grep TARGET binutils/config.h

I got

[hjl@gnu-6 build-x86_64-linux]$ grep TARGET binutils/config.h
#define TARGET "x86_64-unknown-linux-gnu"
#define TARGET_PREPENDS_UNDERSCORE 0

Re: TARGET undefined in bucomm.c

[Luke]

After unpacking the source tarball, there is only config.in, and it has this:

#undef TARGET
#undef TARGET_PREPENDS_UNDERSCORE

after running configure as I described, it has the same thing, and
config.h has not been generated at this point.

After running make, and failing, config.h is generated and has this:

#define TARGET "arm-none-eabi"
#define TARGET_PREPENDS_UNDERSCORE 0

bucomm.c does not have a line:
#include "config.h"

When I add that line to bucomm.c, bucomm.o is built, but then it fails
again on cxxfilt.c, which also does not #include "config.h".  Here is
the error I get for that:
gcc -DHAVE_CONFIG_H -I.  -I. -I. -I../bfd -I./../bfd -I./../include
-DLOCALEDIR="\"/usr/local/share/locale\""
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Wshadow -g -O2 -MT cxxfilt.o
-MD -MP -MF .deps/cxxfilt.Tpo -c -o cxxfilt.o cxxfilt.c
cxxfilt.c:34:31: error: ‘TARGET_PREPENDS_UNDERSCORE’ undeclared here
(not in a function)
make[4]: *** [cxxfilt.o] Error 1

TARGET_PREPENDS_UNDERSCORE is #defined in config.h.  Adding it to
cxxfilt.c lets it compile, but with a warning:
gcc -DHAVE_CONFIG_H -I.  -I. -I. -I../bfd -I./../bfd -I./../include
-DLOCALEDIR="\"/usr/local/share/locale\""
-Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall

-MD -MP -MF .deps/cxxfilt.Tpo -c -o cxxfilt.o cxxfilt.c
In file included from cxxfilt.c:32:0:
config.h:157:0: warning: "PACKAGE" redefined
../bfd/config.h:245:0: note: this is the location of the previous definition

and finally binutils finishes compiling, but then gas fails, with
similar errors that would seemingly be fixed if the appropriate files
were pound including config.h

Is there some other way I should be compiling so that these define
statements are inserted correctly, or should these .c files actually
be #including config.h?  Or maybe the config.h needs to be included in
just one top level header file and that would fix all of this?

Re: TARGET undefined in bucomm.c

[Luke]

Upon further inspection, it looks like:
-- in libiberty nearly every .c file has #include "config.h"  or
#include <config.h>
-- in bfd nearly every .c file has #include sysdep.h, which in turn
has #include "config.h"
-- in gas, nearly every .c file has #include "as.h", which in turn
#includes "config.h"

In contrast, in binutils, only these three files #include "config.h":
elfedit.c
readelf.c
syslex.c

In my build case, at least bucomm.c and cxxfilt.c needed some things
that were defined in config.h.  I don't think me just throwing #define
"config.h" statements into other peoples source constitutes a proper
bugfix, but I don't see how else this can be fixed.  How is target
getting defined in bucomm.c when other people build it?  I tried
configure with no options, and this still gives the same error, so it
seems there is something about my system that is maybe causing
configure to generate a makefile which doesn't properly define TARGET
in bucomm.c and TARGET_PREPENDS_UNDERSCORE in cxxfilt.c.

It really seems like that this needs to be taken care of, either by
adjusting the source to correctly #include things, or adjusting the
build to properly #define things in the compiler flags.

I'm not a computer scientist, nor do I really have any clue of how
binutils is designed, organized or built, but I can see that there is
a problem here.

What is the right approach to fixing this?

In the binutils sysdep.h includes alloca-conf.h which includes config.h.

Why is that not working for you?

Re: TARGET undefined in bucomm.c

[Luke]

Ian,
  I don't know why it isn't working.  What you state is correct, but
for some reason, TARGET is not defined in bucomm.c when it attempts to
compile it.  Again, here is the error message:

make[4]: Entering directory
`/home/luke/repos/summon-arm-toolchain/binutils-2.21/build/binutils'

in this function)
../../binutils/bucomm.c:160:24: note: each undeclared identifier is
reported only once for each function it appears in

I tried putting a #warning into build/binutils/config.h, and the
warning is printed when compiling other files in binutils,
specifically syslex.c.  However, no warning is echoed when bucomm.c is
compiled, indicating to me that this config.h is not being included,
but perhaps another one is?  I put this into build/binutils/config.h:
#warning "build/binutils/config.h is included"

this warning is echoed when building syslex:

but not when building bucomm.c.  So config.h *isn't* being included,
for some reason.  I don't know which config.h is being included by
alloca-conf.h, but it isn't the generated binutils/config.h.  The only
major difference I can see is the -I flags.  Could this have something
to do with it?

Run something like

make CFLAGS="-g -O2 --save-temps" bucomm.o

That will create, besides bucomm.o, a file bucomm.i.  In the first 20
lines of bucomm.i you should see an entry for config.h.  Where is
config.h being found?

When I try it, I see the appended, which shows config.h being included
from the binutils build directory, as expected.

Here are the first lines of bucomm.i:

# 1 "<built-in>"

So, for some reason, it is finding config.h in the bfd folder.

What should I do to fix this?

Don't put build directory inside binutils source tree.

Second, I tried a build in the source tree:

Finally, if I make a build folder inside of the source tree, I get the
same exact result, which is what I reported previously.

So this doesn't seem to be the source of the problem.

Re: TARGET undefined in bucomm.c

Yes.  In the build folder (next to the source folder) there are these:
$ find build -name "config.h"
./binutils/config.h
./opcodes/config.h
./libiberty/config.h
./intl/config.h
./bfd/config.h

the bucomm.o target is including finding bfg/config.h, instead of
binutils/config.h:
# 1 "../../binutils-2.21/binutils/bucomm.c"
# 1 "/home/luke/repos/summon-arm-toolchain/build/binutils//"

I don't know why that is, but I think it must be the reason TARGETS is
undefined.

Re: TARGET undefined in bucomm.c

I think all the config.h files are generated, so the source folder
doesn't have any:
luke@ThinkPad-W510:summon-arm-toolchain(master)$ find binutils-2.21/
-name "config.h"
luke@ThinkPad-W510:summon-arm-toolchain(master)$ find binutils-2.21/
-name "config.*"
binutils-2.21/config.sub
binutils-2.21/binutils/config.in
binutils-2.21/config.rpath
binutils-2.21/opcodes/config.in
binutils-2.21/gas/config.in
binutils-2.21/libiberty/config.h-vms
binutils-2.21/libiberty/config.in
binutils-2.21/intl/config.intl.in

binutils-2.21/bfd/config.in
binutils-2.21/gprof/config.texi

Is that what you meant?

Unless you have been editing include/alloca-conf.h, I'd say you have a
broken gcc.  The first line of alloca-conf.h is
#include "config.h"

There isn't a config.h in source_path/include/, so gcc should start
looking in the -I paths you showed on your gcc command line.  The
first one was "." and you're in build_path/binutils/ when compiling
bucomm.c, so gcc should pick up the config.h in that dir.  (Adding -v
to the gcc command line will verify the search paths.)  config.h is
readable isn't it?

I just did a clean install of Ubuntu 11.04 on a virtual machine and it
compiled just fine out of the box.  My host machine is Kubuntu 11.04
and gcc is the same version and seems to be built with the same flags,
so it would be weird if those two things were the same yet gcc was
somehow to blame.  Maybe something else with my build environment is
messing things up?

You didn't show the command here.  Did it have -I. first, as it should?
If so, I don't see how that #include search path is possible.  And what
is /home/luke/usr/include doing on the search path?  Do you have CPATH
or C_INCLUDE_PATH set in the environment?

Re: TARGET undefined in bucomm.c

The same compiler, complied with the same configure flags, builds
binutils on the same version of Ubuntu (11.04) installed on a virtual
machine without these errors.

CPATH is not defined as an environment variable.

C_INCLUDE_PATH is and has one directory entry:
/home/luke/usr/include.  Unsetting C_INCLUDE_PATH fixed the problem.
That folder did not have much in it, I don't think any of the headers
in there would have been included, but I could be wrong.  Here are the
contents of that folder:

luke@ThinkPad-W510:include$ pwd
/home/luke/usr/include
luke@ThinkPad-W510:include$ ls
ecpg_config.h    libpq-events.h      pgtypes_error.h      sqlca.h
ecpgerrno.h      libpq-fe.h          pgtypes_interval.h   sqlda-compat.h
ecpg_informix.h  libusb-1.0          pgtypes_numeric.h    sqlda.h
ecpglib.h        pg_config.h         pgtypes_timestamp.h  sqlda-native.h
ecpgtype.h       pg_config_manual.h  postgres_ext.h       vtk-5.9
libftdi          pg_config_os.h      postgresql
libpq            pgtypes_date.h      sql3types.h
luke@ThinkPad-W510:include$

As a quick test, I moved the contents of that directory elsewhere, so
it was empty, and then reconfigured and ran make.  The same build
error comes back.  So it seems that the contents of that folder are
not the problem, but rather the way the environment variable is
defined.  Here is my relevant .bashrc:

# Path to search for C include files
export C_INCLUDE_PATH=$HOME/usr/include:$C_INCLUDE_PATH

and this is what it is set to immediately prior to the configure and make steps:
$ echo $C_INCLUDE_PATH
/home/luke/usr/include:

The colon at the end of C_INCLUDE_PATH seemed fishy to me, so I
redefined it without the colon:
$ export $C_INCLUDE_PATH=/home/luke/usr/include

And this fixes everything, even when /home/luke/usr/include has all of
the headers that I had installed there.

So, am I correct in understanding that C_INCLUDE_PATH should not have
a trailing colon, and if it does, it may wreak havoc on things in
non-obvious ways?  Might this be a bug in how gcc (or some other part
of the build process) parses the environment variables?

It would be nice understand why this happened, because even though I
am able to get binutils to build, I have no idea why, and the errors I
got were far from informative.

In any PATH variable, a trailing (or leading) colon means the current
directory (i.e., ".").  In this case it was breaking things because it
meant that the explicit -I. command line option was being discarded as a
duplicate, and so "." was being searched at the wrong point in the
search path.

Ok this makes sense now.  Thank you for helping me figure this out.
