note that in the first compilation it's using mpicc instead of mpicxx. Setting both CC and CXX to mpicxx allows it to continue, but it shouln't be using the $CC variable in the first line.

when using gcc/g++ this works without any changes.

What version of instant does this issue relate to? We have recently updated the whole JIT chain in FEniCS to use CMake to address this particular issue.

It looks like your error report relate to an older instant using distutils. Have you tried upgrade to master for all packages?

I have a similar issue on mac. Even though I have compiled with gcc-4.7 I get the clang compilers selected by default when using instant\cmake. A fix is to set both CC and CXX, but I have to do this manually every time I open a terminal so as not to mess with other aspects of my system.

[Johan Hake]

Is it the same error message in the log file? If so that indicates that you are not using CMake. Could you please post the content of the log file when you compile with cmake?

I think 4c9c62c fixed this.
