Thanks for the response. Concerning the test, don't comment out "make test", because that is not the correct command. Just replace it with "make check".

Here's my suggested PKGBUILD: https://gist.github.com/wesbarnett/6d521b66301ebe9eb786 Then people can follow the wiki article if the want double precsion, MPI, GPU, etc.

Sorry to keep commenting, the license should be LGPL, not GPL. Also "make check" works for me, not "make test".

A GROMACS-enhanced fftw library is now available in AUR as "fftw-bettersimd". Also a few thoughts: GROMACS should detect the appropriate SIMD instructions for your processor, so that flag probably doesn't need to be set. Also, is -DGMX_OPENMP a real flag? I can't find it in the documentation. I also think that a better default would be better to just have it compile for single precision, since most people don't need double precision. I'm currently working on the GROMACS wiki page.

One other thing - you shouldn't have to set SIMD instructions unless you get an error, so that probably should be removed. By default GROMACS chooses the best (http://www.gromacs.org/Documentation/Installation_Instructions_5.0#simd-support).

One suggestion - the current PKGBUILD has both single and double precision enabled by default. I think a more "sane" default would just be single precision since according to the GROMACS site double precision is "slower, and not normally useful." (http://www.gromacs.org/Documentation/Installation_Instructions_5.0#typical-gromacs-installation)

Thanks for the tip. I was always wondering how come none of the gromacs developers where unaware of this problem. Now, I see. The problem was in my side. I will add this tip in the next release.
