Notes

EasyBuild 3.0 roadmap

• https://github.com/hpcugent/easybuild/issues/255

RPATH support

• https://github.com/hpcugent/easybuild-framework/pull/1942
• building GCC 5.4.0 with --rpath enabled fails in a weird way
  • /usr/bin/install: cannot stat '.libs/libcc1.so.0.0.0': No such file or directory
  • libtool command that is supposed to generate that file is skipped somehow
  • no other errors found in the build log, nor in the rpath wrapper logs...

deprecating old/inactive toolchains

• https://github.com/hpcugent/easybuild/wiki/Deprecated-toolchains

Cross compiling

• e.g. with FFTW: configure with --enable-avx2 or not?
