I'm obviously doing something daft, as it's failing to build with those options for me. Here's my full configure command: ../gcc-4.5.0/configure \ --target=$LFS_TGT --prefix=/tools \ --disable-nls --disable-shared --disable-multilib \ --disable-decimal-float --disable-threads \ --disable-libmudflap --disable-libssp \ --disable-libgomp --enable-languages=c \ --with-gmp-include=/mnt/lfs/sources/gcc-build/gmp \ --with-gmp-lib=/mnt/lfs/sources/gcc-build/gmp Here's some gmp-related bits that results: checking for gmp.h... yes ... checking for recent GMP... yes checking for __gmpz_init in -lgmp... no configure: error: libgmp not found or uses a different ABI. And here's what's in /mnt/lfs/sources/gcc-build/mpfr/config.log: configure:13376: checking for __gmpz_init in -lgmp configure:13401: gcc -o conftest -g -O2 -ffloat-store -I/mnt/lfs/sources/gcc-build/gmp -L/mnt/lfs/sources/gcc-build/gmp conftest.c -lgmp >&5 /usr/bin/ld: cannot find -lgmp collect2: ld returned 1 exit status What parameters, exactly, did you pass to get a successful build of GCC with MPFR-3.0.0 in-tree?
