It would be good to know the output of this now: $ ldd /usr/libexec/gcc/x86_64-pc-linux-gnu/4.9.4/cc1 In your previous message it had lines libmpfr.so.4 => /usr/lib/x86_64-linux-gnu/libmpfr.so.4 (0x00007fcb73c96000) libmpfr.so.6 => /usr/lib/x86_64-linux-gnu/libmpfr.so.6 (0x00007fcb72c3e000) which looks like a library conflict (I suppose that's what Francois referred to " the compiler is in a broken state at the system level") Perhaps it got fixed by your call to apt-get (and if not, it's still means a broken gcc toolchain). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
