             Bug #: 52226
           Summary: Trunk fails to bootstrap on Mac OS X.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: manphiz@gmail.com


Trunk (last tested with revision 184145) has been failing to bootstrap for some
time (last checked last Tuesday) on my macbook with Snow Leopard. The configure
options are:

${SOURCE_PATH}/configure \
    --prefix=${PREFIX} \
    --with-gmp=${PREFIX} \
    --with-mpfr=${PREFIX} \
    --with-mpc=${PREFIX} \
    --with-ppl=${PREFIX} \

    --enable-cloog-backend=isl \
    --program-suffix=-${VERSION} \

IS this a copy & paste error?  It must be "fully" not "full"

Indeed that was an error. I fixed that and added "--enable-stage1-checking" and
"--enable-lto", but it still failed with the same error. New configure options:

${SOURCE_PATH}/configure \
    --prefix=${PREFIX} \
    --with-gmp=${PREFIX} \
    --with-mpfr=${PREFIX} \
    --with-mpc=${PREFIX} \

And new build log will be uploaded to supersede the previous one.

You probably don't want this, some of the concept checks are incompatible with
C++11, you shouldn't enable them at configure time, you can still use them
later with -D_GLIBCXX_CONCEPT_CHECKS

>     --enable-decimal-float \
>     --enable-fully-dynamic-string \
>     --enable-libstdcxx-debug \
>     --enable-libstdcxx-time \

This implies you want to use C++11, so you probably don't want to permanently
enable concept checks.

If your build fails it's usually a good idea to try *removing* options to find
the smallest set that can reproduce the bug, instead you're adding more
options.

>     --enable-static \
>     --enable-shared \
>     --enable-threads \

These are redundant, you're explicitly setting default behaviour.

>     --enable-version-specific-runtime-libs

This is broken on x86_64 multilib

I don't think these are the cause of your problem, I just think you'll find it
easier to identify the real problem if you keep it simple instead of adding
loads of unnecessary complication.

Thanks for the detailed explanation for these options. I'll tweak with them and
report back.

Could the problem be that you don't have an assembler that supports 64-bit?

It's a Mid-2009 macbook pro (MacBookPro5,5) that preinstalled with Snow
Leopard. The only difference is that it used to boot with 32-bit kernel and now
I enabled 64-bit kernel by hand. I'm not sure but I guess it should support
64-bit stuff.

What does return '/usr/libexec/gcc/darwin/x86_64/as -v' (after it you need to
interupt as with ctrl-C)? For me it gives

Apple Inc version cctools-795~45, GNU assembler version 1.38

I configure with

Configured with: ../work/configure --prefix=/opt/gcc/gcc4.7w
--enable-languages=c,c++,fortran,objc,obj-c++,java,ada,lto --with-gmp=/opt/mp
--with-system-zlib --with-cloog=/opt/mp --enable-cloog-backend=isl --enable-lto

and it works!-)

The assembler here reports the same:

$ /usr/libexec/gcc/darwin/x86_64/as -v
Apple Inc version cctools-795~45, GNU assembler version 1.38
^CInterrupted by signal 2

And after some checking I found that by disabling "--enable-libstdcxx-debug"
the compile process passed the current error, but failed later right after
comparing stage 2 and 3:

I guess this may be related to "--enable-fully-dynamic-string". But it looks
like a difference issue[1][2].

[1] http://trac.macports.org/ticket/27237
[2] http://trac.macports.org/ticket/31171

Anyway, "--enable-libstdcxx-debug" causing bootstrap failure should be a
problem.

--- Comment #13 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I've just checked: current trunk bootstraps fine with --enable-libstdcxx-debug,
so this probably got fixed at some point. If you still see it, with a currently
supported version of GCC, please feel free to reopen the bug report and give
the necessary details.
