--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Thanks for filing this, and sorry for the breakage. Is there a cfarm machine that I ought to be able to reproduce this on? I'm trying with cfarm111, but get this configure error: $ ../src/configure --with-gmp=/opt/cfarm/gmp-latest --with-mpfr=/opt/cfarm/mpfr-latest --with-mpc=/opt/cfarm/mpc-latest --disable-bootstrap --enable-languages=c,c++,fortran [...snip...] checking for the correct version of gmp.h... no configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+. $ file /opt/cfarm/gmp-latest /opt/cfarm/gmp-latest: symbolic link to /home/iulius/autobuild/bin/gmp-6.1.2. $ ls /home/iulius/autobuild/bin/ [no output]
