Subject: [Bug other/45760]  New: GCC build fails: can't find MPC
Date: Thu, 23 Sep 2010 13:07:00 -0000	[thread overview]
Message-ID: <bug-45760-19725@http.gcc.gnu.org/bugzilla/> (raw)

I believe this is a bug in GCC 4.5.1 build system related to the introduction
of MPC.

I'm compiling GCC 4.5.1 and all its dependencies in my home directory and
installing all (make install) at $HOME/OpenFOAM/ROOT

At some GCC build stage it fails with this messages:

---------------------------------------

Side note: /bgpusr3/avibrz == $HOME
Having a look at
/bgpusr3/avibrz/OpenFOAM/gcc-build/powerpc64-unknown-linux-gnu/libgcc/config.log
I find this:

---------------------------------------

/bgpusr3/avibrz/OpenFOAM/gcc-build/./gcc/cc1: error while loading shared
libraries: libmpc.so.2: cannot open shared object file: No such file or
directory
configure:3237: $? = 1
---------------------------------------

But libmpc.so.2 is there. I even took care of creating artificial symbolic
links to satisfy this bizarre 'powerpc64-unknown-linux-gnu' under ROOT.

This is how I'm configuring GCC as I took care of passing correct directories
for MPC installation:

---------------------------------------
gcc-build$ ../gcc-4.5.1/configure --prefix=$HOME/OpenFOAM/ROOT
--with-stage1-ldflags="-L$HOME/OpenFOAM/ROOT/lib"
--with-gmp="$HOME/OpenFOAM/ROOT" --with-mpfr="$HOME/OpenFOAM/ROOT"
--with-ppl="$HOME/OpenFOAM/ROOT" --with-mpc="$HOME/OpenFOAM/ROOT"
--enable-languages=c++,fortran
---------------------------------------

Any tip ?
