on how to compile gcc-4.6 correctly?

on how to compile gcc-4.6 correctly?

[Dennis]

Hi, all,
  I'm using gentoo distribution (including gmp/mpfr/mpc) that could compile
gcc-4.5.0, 4.5.1, and many snapshots correctly, including the recent one gcc-4.5-20100902,
but when I tried to compile gcc-4.6, any snapshot version, even recent gcc-4.6-20100904,
it always failed, the recent one failure compiling is:

../../gcc-4.6-20100904/gcc/c-decl.c: In function 'grokdeclarator':
../../gcc-4.6-20100904/gcc/c-decl.c:5533: warning: format not a string literal and no format arguments

I don't know what happened with that? When I search the 'ggc_alloc_cleared_lang_type' macro,
it really doesn't exist in the gcc-4.6-20100904 source, nor under /usr/include, so what is
that macro real dependency? the prerequisites page seems not help me,
http://gcc.gnu.org/install/prerequisites.html

Who have successfully build gcc-4.6 please help me, or have any clue, I have searched that ggc_alloc_cleared_lang_type
through google, but didn't find out any meaningful results,

please make sure have my email address on cc-list that I can receive your email, because I didn't subscribe such
high volume mailing list,

Thank you very much,

hm... an obvious question would be if you have your toolchain correct?
(but you probably do..(I used this to build 
4.6.0..:http://cross-lfs.org/view/svn/x86_64-64/))

in your case I see something with lang... maybe your CFLAGS are set 
wrong to the wrong machine?! over here my CFLAGS look like this:
CFLAGS="-m64 -mtune=core2 -march=core2 -O2 -pipe -fomit-frame-pointer 
-fstack-protector -w" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}"

keep in mind this is for a intel iMac... your system could be diff..

Yes, I think the binutils/gmp/mpfr/mpc all dependencies are correct, otherwise why I can compile all gcc-4.5.x version correctly?
On the same system, gcc-4.5.x (4.5.0 and 4.5.1 and 4.5-20100902/... multiple snapshots) all can compile correctly, I install them into separate directories, and have verified those compilers can compile many source packages correctly;

> (but you probably do..(I used this to build

but this still didn't explain what's the "ggc_alloc_cleared_lang_type" macro? all through gcc source it's only used by gcc/c-decl.c file, but it has no definition under gcc source header files, nor under /usr/include;

I didn't use any special CFLAGS, when I try to compile gcc-4.5.x or this gcc-4.6 snapshot, I just use "../gcc-4.6-20100905/configure --with-arch-64=athlon64 --with-arch-32=i386", I tried to get a multilib compiler that could generate default athlon64 optimized code for 64bit and i386 code for 32bit;

The same "--with-arch-64=athlon64 --with-arch-32=i386" works well during compiling gcc-4.5.x but why not work on gcc-4.6 ???

ah... if gcc 4.5.0 builds right, but 4.6.0 does not then everything is
good(toolchain).. sounds like your going to have to file a bug with
gcc since 4.6.0 is so new..
(keep in mind it's late here so I might have left a few things out..).

This seems to be defined in a header generated during the build
into the $BUILD/gcc :

[root@localhost gcc]# grep ggc_alloc_cleared_lang_type *.h
gtype-desc.h:#define ggc_alloc_cleared_lang_type_u() ((union lang_type_u 
*)(ggc_internal_cleared_alloc_stat (sizeof (union lang_type_u) 
MEM_STAT_INFO)))

On CentOS 5.5/ia32 the build seemed to succeed for the
'x86_64-linux-gnu' target, using gcc-4.1.2 as the host
and build compiler.  Must check the Fedora 13/x86_64
host with its gcc-4.4.4 too but I wouldn't expect any
change with it...

So maybe the Gentoo distro has some problem...

No, I've tried compiling gcc-4.6-20100911 on ubuntu 10.04, the same
problem also happened;

and I also found that macro was defined in a generated header file, in
the gcc build directory;

renquan@flyer-1-1:~/src/gcc-4.6-build$ grep -RsInw
ggc_alloc_cleared_lang_type gcc/
gcc/gtype-desc.h:2451:#define ggc_alloc_cleared_lang_type() ((struct
lang_type *)(ggc_internal_cleared_alloc_stat (sizeof (struct
lang_type) MEM_STAT_INFO)))

this definition just doesn't accept any arguments, but inside
gcc/c-decl.c:7028 and 7311:

        space = ggc_alloc_cleared_lang_type (sizeof (struct lang_type));

  lt = ggc_alloc_cleared_lang_type (sizeof (struct lang_type));

both passes 1 argument, so the compiler report error, so the problem
is how can you succeed compiling that?

In all stages during the native bootstrap this define was :

gtype-desc.h:#define ggc_alloc_cleared_lang_type(SIZE) ((struct 
lang_type *)(ggc_internal_cleared_alloc_stat (SIZE MEM_STAT_INFO)))

in Fedora 13 with the earlier gcc-4.6-20100904 snapshot...

My RedHat-based systems (CentOS, Fedora) will generate a different
'#define' for this. Why the Gentoo and Ubuntu are working differently
is hard to say... Ok, I can try also Ubuntu 10.04 so let's see what
it does...

I am the author of how these macros are generated, but somehow I have
missed this thread initially. Could you send me off-list that
gtype-desc.h file?

The problematic gtype-desc.h has been sent to Laurynas separately, I
was compiling only the gcc-core-4.6-20100911.tar.bz2 tarball, because
I only want a c compiler; I searched the macro
ggc_alloc_cleared_lang_type through out the source and build
directory, only one definition and two usage, with conflict arguments
passing:

../path/to/gcc-build$ grep -RsInw ggc_alloc_cleared_lang_type
../gcc-4.6-20100911/ gcc/
../gcc-4.6-20100911/gcc/c-decl.c:7027:  space =
ggc_alloc_cleared_lang_type (sizeof (struct lang_type));
../gcc-4.6-20100911/gcc/c-decl.c:7310:  lt =
ggc_alloc_cleared_lang_type (sizeof (struct lang_type));
gcc/gtype-desc.h:2451:#define ggc_alloc_cleared_lang_type() ((struct
lang_type *)(ggc_internal_cleared_alloc_stat (sizeof (struct
lang_type) MEM_STAT_INFO)))

and in fact, I'm interested why this Kai Ruottu got a
ggc_alloc_cleared_lang_type_u macro with 0 arguments in gtype-desc.h
while my gtype-desc.h doesn't have that macro? I'm not sure he could
get ggc_alloc_cleared_lang_type macro or not, so how can he succeed
his compilation;

Thanks. I assume that you pass --enable-languages=c to configure?

I will investigate this tomorrow and will get back to you.

No, just a very simple configure and make command:

../path/to/gcc-4.6-build$ time { ../gcc-4.6-20100911/configure
--prefix=/usr --disable-nls --with-system-zlib && make --debug=b; } |&
tee build-log

Because the source code is uncompressed from gcc-core-4.6-..., it only
includes the c compiler, I leave the configure to figure out there is
only c compiler source code;

Re: on how to compile gcc-4.6 correctly?

[Dennis, CHENG Renquan]

For anyone could succeed compiling gcc-4.6, could you paste a correct
ggc_alloc_cleared_lang_type macro ?

just run this grep command under your build directory,

gcc-4.6-build$ grep -RsInw ggc_alloc_cleared_lang_type gcc/
gcc/gtype-desc.h:2451:#define ggc_alloc_cleared_lang_type() ((struct
lang_type *)(ggc_internal_cleared_alloc_stat (sizeof (struct
lang_type) MEM_STAT_INFO)))

thanks,

[root@hp-pavilion build]# grep -RsInw ggc_alloc_cleared_lang_type gcc/
