Dear Victor, When you run the configure command by hand you should also have set the environment variables that are used by the ConfigureMake easyblock. One way to see what these are is with: eb -x OpenMPI-2.1.1-ClangGCC-2017b.eb the config.log should then help you diagnose the problem.

I've made some custom easyconfigs, they're in the attachment. I get an error that the c compiler is not working, when I run the configure command by hand using the same options and with the same modules loaded it configure just fine. Any thoughts on this?
