             Bug #: 54260
           Summary: GCC 4.7.1 fails to build.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: Fetrovsky@gmail.com


I don't know where to report this problem --- apologies if this is the wrong
place.  GCC 4.7.1 is not building for me.  I ran configure without any
arguments and this is what I get when I do make:

Can you attach x86_64-unknown-linux-gnu/libgcc/config.log ?

Hi,

Thanks for the response.  I've looked at the corresponding config.log, and
looked into the problems there, but I can't seem to make sense of what's going
on.  I get:

So I tried compiling the test file (conftest.c) like so:

/home/Feto/sw/gcc/build/./gcc/xgcc -B/home/Feto/sw/gcc/build/./gcc/
-B/usr/local/x86_64-unknown-linux-gnu/bin/
-B/usr/local/x86_64-unknown-linux-gnu/lib/ -isystem
/usr/local/x86_64-unknown-linux-gnu/include -isystem
/usr/local/x86_64-unknown-linux-gnu/sys-include    -o conftest -g -O2  
conftest.c

I made sure libmpc is properly installed, the proper location is passed to
configure, and so on.  I'm not sure what else to try.

[Feto@fet libgcc]$ ll /usr/local/lib/libmpc*
-rw-r--r-- 1 root root 211870 Aug 14 15:27 /usr/local/lib/libmpc.a

[Feto@fet libgcc]$ ld -lmpc

Thank you,

You failed to inform the dynamic linker where to find libmpc.so.  Set
LD_LIBRARY_PATH to something like "/usr/local/lib:".

These links explain that the support libraries must be in the dynamic linker's
search path:

If you follow those instructions it will work. That's why I provided the links.
