Set Instant compiler

Asked by Paul Constantine

How can I set the compiler in Instant? Right now it's using gcc, but I'd like it to use icc.

Here's a recent error in compile.log:

$ cat compile.log
running build_ext

Try setting the CC and CXX environment variables.

By setting CC and CXX like Johannes suggests will make distutils to use
that. We are, however, working on getting instant to use CMake instead
of distutils. Then we can use all the configuration variables acquired
during configuration of UFC and DOLFIN, like compiler type, in the
generation of the JIT compiled extension modules. This will get merged
into trunk soon.
