Awesome!. Please also look into Travis. I have not been able to crack it.

Then I will put strict tests in place and logs in new GEMMA features.

At the moment the build is failing with

ld: source/faster_lmm_d/optmatrix.o: undefined reference to symbol 'dsyev_'
/gnu/store/rmkyk4n0m7ycarggdp68938srsd544ap-profile/lib/liblapack.so.3: error adding symbols: DSO missing from command line

These functions are actually part of openblas so we do not need to link in lapack. What I need to do is create a clean Guix environment to build faster_lmm_d so I can isolate the build profile (no libraries can bleed in). We need that to create a reproducible binary. This is a bit of work and requires good internet. More soon.
