Previous message should read : As for gmp & mpc, they were present in my gcc src folder. The bug I described only occurs when using MPFR v3.0 instead of v2.4.2. Version of MPC was 0.8.2 and GMP 5.0.1. GCC compilation will fail even WITH the gmp/mpc/mpfr sources present in gcc source folder when make tries to run mpfr-configure. Copying the two missing GMP source files into /gcc-build/gmp will fix this. Best regards, Thibaud F.
