I'm trying to build a gcc cross-compiler.
The configure script was passed the following arguments: --prefix=${tools}/usr
--build=${host} --host=${host} --target=${target} --with-sysroot=${sysroot}
--with-newlib --enable-languages=c --with-gmp=${tools}/usr
--with-mpfr=${tools}/usr --disable-decimal-float --disable-threads
--disable-shared --disable-libmudflap --disable-libssp --disable-libgomp
--disable-multilib
Where: tools=/media/data/linux/tools host=x86_64-cross-linux-gnu
target=x86_64-unknown-linux-gnu sysroot=/media/data/linux/sysroot
I got the following error:

make[1]: *** [configure-target-libgcc] Error 1

make: *** [all] Error 2
The relevant config.log in the build directory contains the following error
message:
/media/data/linux/sources/gcc-4.4.4-build/./gcc/cc1: error while loading shared
libraries: libgmp.so.10: cannot open shared object file: No such file or
directory
The fact is that libgmp.so.10 is present in the place where gcc should look
for, that is /media/data/linux/tools/usr/lib64.
The problem occurs only with gmp-5.0.1; if I use gmp-4.3.2, instead, I obtain
no build failures.
