I'm trying to build gcc 4.6.3 on a Linux From Scratch i586 system:
http://www.linuxfromscratch.org/lfs/view/development/chapter06/gcc.html
I am using the libiberty.a provided by binutils mod. My current gcc
version is 4.1.2. I am using a separate build directory (gcc-build).
My configure line is:
../gcc-4.6.3/configure --prefix=/usr --libexecdir=/usr/lib --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++,fortran,go,objc,obj-c++ --disable-multilib --disable-bootstrap --with-system-zlib
During the build, I get an error for go:
g++ -c -I ../../gcc-4.6.3/gcc/go -I ../../gcc-4.6.3/gcc/go/gofrontend -I. -Igo -I../../gcc-4.6.3/gcc -I../../gcc-4.6.3/gcc/go -I../../gcc-4.6.3/gcc/../include -I../../gcc-4.6.3/gcc/../libcpp/include -I../../gcc-4.6.3/gcc/../libdecnumber -I../../gcc-4.6.3/gcc/../libdecnumber/bid -I../libdecnumber -fomit-frame-pointer -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -DHAVE_CONFIG_H ../../gcc-4.6.3/gcc/go/gofrontend/dataflow.cc -o go/dataflow.o
In file included from ../../gcc-4.6.3/gcc/go/gofrontend/dataflow.cc:7:
../../gcc-4.6.3/gcc/go/go-system.h:118:3: error: #error "requires hash table type"
../../gcc-4.6.3/gcc/system.h:462: error: declaration of C function 'const char* strsignal(int)' conflicts with

.
.
It seems that gccgo does not see that I HAVE_STRSIGNAL and
HAVE_TR1_UNORDERED_MAP and HAVE_EXT_HASH_MAP although my
gcc-build/gcc/config.log:
| #include <unordered_map>
configure:8572: result: no
configure:8583: checking for tr1/unordered_map
configure:8583: g++ -E conftest.cpp
configure:8583: $? = 0
configure:8583: result: yes
configure:8594: checking for ext/hash_map
configure:8594: g++ -E conftest.cpp
configure:8594: $? = 0
configure:8594: result: yes
.
.
configure:8835: checking for strsignal
configure:8835: gcc -o conftest -g conftest.c >&5
configure:8835: $? = 0
configure:8835: result: yes
and my gcc-build/gcc/auto-host.h:
/* Define to 1 if you have the `strsignal' function. */
#ifndef USED_FOR_TARGET
#define HAVE_STRSIGNAL 1
#endif
/* Define to 1 if you have the <ext/hash_map> header file. */
#ifndef USED_FOR_TARGET
#define HAVE_EXT_HASH_MAP 1
#endif
/* Define to 1 if you have the <tr1/unordered_map> header file. */
#ifndef USED_FOR_TARGET
#define HAVE_TR1_UNORDERED_MAP 1
#endif
indicate that I do in fact have these. It seems gccgo (and only gccgo) is
not properly seeing these configure settings because
gcc-4.63/gcc/go/go-system.h does not seem to see the configure settings
for HAVE_TR1_UNORDERED_MAP or HAVE_EXT_HASH_MAP and neither does
gcc-4.63/gcc/system.h (under gccgo) for HAVE_STRSIGNAL.
A search found this recent post to gcc-help which may be related,
(but was for gcc 4.6.1 and did not involve gccgo):
http://gcc.gnu.org/ml/gcc-help/2011-12/msg00021.html
However, that problem does not seem to have been solved.
Any suggestions or advice?
Thanks in advance,
Mike Shell

I don't know what is going wrong here. I recommend running the failing
command yourself, adding the -H option, and see where auto-host.h is
coming from. Perhaps the compilation is somehow picking up the wrong
auto-host.h.

Ian,
Thank you. OK, I did. The result is below. I don't see (well, at least
a search by my text editor did not find) *any* reference to auto-host.h.
I wonder if *anyone* has tried to build gccgo on 4.6.3 (on an x86
system) yet (or even 4.6.x for that matter). If it is known to work at
all, then I suppose I can test some changes to my initial call to
configure (e.g., try a more "default" setting), but as you might guess,
such test compile runs take hours on my old system. So, I can't hammer
away with fresh test recompilations several times an hour like I could
with a simpler software package (or a much faster system).
Mike

The problem is here:

This needs to be gcc/config.h, not libdecnumber/config.h. It's picking
up libdecnumber/config.h because of the -I../libdecnumber on the command
line. That is odd, because on the command line -I. appears before
-I../libdecnumber. The command should be run in the gcc build
directory. There should be a config.h in that directory. The
-I. should cause that config.h to be used first. Do you in fact have a
config.h in that directory? If so I don't understand why it is not
being used instead of ../libdecnumber/config.h.

Sure, many people have, including me just before I sent the previous
reply. It worked fine for me on x86_64 GNU/Linux.

Ian,
Yes, there is a gcc-build/gcc/config.h which pulls in auto-host.h and I
don't see any file permission problems. The compile command was run in
gcc-build/gcc My g++ version is 4.1.2. Perhaps there is an include bug with
4.1.2. What about potential problems with environment variables that
could do this? Perhaps I should try building using bootstrapping.
I bet this is the very same problem that went wrong with Pablo Barrio
back in December 2011:
http://gcc.gnu.org/ml/gcc-help/2011-12/msg00021.html
But he was using 4.6.1 to compile 4.6.1. If this is the same problem,
then it is not caused by any 4.1.2 bug, but rather something
else that is causing both compilers to fail to pull in gcc/config.h
I guess the question becomes: What possible circumstances could cause
g++ -c -H -I ../../gcc-4.6.3/gcc/go -I ../../gcc-4.6.3/gcc/go/gofrontend
-I. -Igo -I../../gcc-4.6.3/gcc ......
running in gcc-build/gcc to fail to pull in gcc-build/gcc/config.h ?
Cheers,
Mike

Possible but unlikely.

Possible but unlikely. E.g., you could have set C_INCLUDE_PATH to
../../gcc-4.6.3/libdecnumber, but I assume that you didn't.
> Perhaps I should try building using bootstrapping.
I would expect that to work, but I have no idea why it would be
required. You could also try configuring using an absolute path to
configure rather than a relative path.

I really can't think of anything. Sorry. It would be great if you
could debug this problem, although in the end it will probably turn out
to be something dumb.

I got it! The file that calls for the include of "config.h" is
gcc-4.6.3/gcc/go/go-system.h
OK, now the rule for -I states:
http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html
"If a standard system include directory, or a directory specified with
-isystem, is also specified with -I, the -I option will be ignored."
Here we have a mechanism whereby an -I can be ignored. So, the question
becomes, what determines, or can alter, the definition of the list of
standard system include directories?
Here we see:
http://gcc.gnu.org/onlinedocs/gcc/Environment-Variables.html#Environment-Variables
"Some additional environments variables affect the behavior of the
preprocessor.
CPATH
C_INCLUDE_PATH
CPLUS_INCLUDE_PATH
OBJC_INCLUDE_PATH
Each variable's value is a list of directories separated by a special
character, much like PATH, in which to look for header files. The
special character, PATH_SEPARATOR, is target-dependent and determined at
GCC build time. For Microsoft Windows-based targets it is a semicolon,
and for almost all other targets it is a colon.
CPATH specifies a list of directories to be searched as if specified with
-I, but after any paths given with -I options on the command line. This
environment variable is used regardless of which language is being
preprocessed.
The remaining environment variables apply only when preprocessing the
particular language indicated. Each specifies a list of directories to be
searched as if specified with -isystem, but after any paths given with
-isystem options on the command line.
In all these variables, an empty element instructs the compiler to search
its current working directory. Empty elements can appear at the beginning
or end of a path. For instance, if the value of CPATH is :/special/include,
that has the same effect as `-I. -I/special/include'.
"
Un huh, and what, pray tell, was in my CPLUS_INCLUDE_PATH?
echo $CPLUS_INCLUDE_PATH
/opt/qt/include:
Ouch! That pesky : without a following directory told it to treat -I. as
a system include directory and thus an -I. on the g++ command line will
be ignored. Clearing CPLUS_INCLUDE_PATH resulted in expected behavior.
Oh, what a tangled web we weave.
Cheers and thank you,
Mike

Very nice. I'll have to remember that one.

And what turned out to be cause of my CPLUS_INCLUDE_PATH typo?
I first thought I just had forgot to delete a :. But, no, this mistake
is even easier to make than that. My /etc/profile had:
export CPLUS_INCLUDE_PATH="$QTDIR/include:$CPLUS_INCLUDE_PATH"
where $CPLUS_INCLUDE_PATH had not been set before. So, taking care
to append rather than to set introduced the problem. FWIW, I have
complied a lot of packages on this system and did not encounter an
unexplained problem related to CPLUS_INCLUDE_PATH until gcc. So,
people might tend to "trust" their system and blame gcc when this
one bites.
Cheers,
Mike
