gcc111 uses gcc-4.8.1 so as an experiment I performed the following test:
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.1/gcc-4.8.1.tar.gz gunzip gcc-4.8.1.tar.gz tar -xf gcc-4.8.1.tar cd gcc-4.8.1 ./configure --prefix="${HOME}/testarea" make -j2 >logfile 2>errlog make install configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+. Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify [..] Gcc recommends that the local libraries libgmp, libmpfr and libmpc be installed on the development machine, which they are, but they do not coordinate with gcc-4.8.1. https://gcc.gnu.org/wiki/InstallingGCC "The difficult way, which is not recommended, is to download the sources for GMP, MPFR and MPC, then configure and install each of them in non-standard locations, then configure GCC with --with-gmp=/some/silly/path/gmp [...]" I have no problem with both techniques of installing gcc, however many modern guides, scripts and cross build systems assume the presence of working gmp, mpfr and mpc as per the gcc documentation provided above. One option might be to update the gcc version, another to update the mpc/mpfr/gmp versions. Either way the canonical test of compiler + standard C library + gmp/mpfr/mpc efficacy is that it can rebuild itself. -bash-4.3$ gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/opt/freeware/libexec/gcc/powerpc-ibm-aix7.1.0.0/4.8.1/lto-wrapper Target: powerpc-ibm-aix7.1.0.0 Configured with: ../gcc-4.8.1/configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --enable-languages=c,c++,fortran --prefix=/opt/freeware --mandir=/opt/freeware/man --infodir=/opt/freeware/info --enable-version-specific-runtime-libs --disable-nls --enable-decimal-float=dpd --host=powerpc-ibm-aix7.1.0.0 Thread model: aix gcc version 4.8.1 (GCC) No such problems were encountered when performing a control test with gcc75 which has gcc-4.9.2. If I am not mistaken, the development headers in /opt/freeware were installed independently and likely never coordinated with the original build of gcc-4.8.1.
