--- Comment #6 from Martin Losch <mlo...@uni-bremen.de> 2011-02-02 09:00:10 UTC --- (In reply to comment #4) As far as I can see (from the header files that came with pre-compiled binaries) this was used: #define MPFR_VERSION_STRING "2.4.1" #define MPC_VERSION_STRING "0.8.1" #define __GNU_MP_VERSION 4 #define __GNU_MP_VERSION_MINOR 3 #define __GNU_MP_VERSION_PATCHLEVEL 1 I have used gdb for minimally, but what is its use here? I cannot create an executable if I do not reduce the optimization level. What do you suggest?
