[Debichem-devel] Bug#834991: gromacs: please disable SIMD on armhf

[Graham Inggs]

Source: gromacs

Severity: wishlist
Tags: patch

Hi Maintainer

Gromacs FTBFS on the Ubuntu armhf buildds.  The Ubuntu armhf buildds
have NEON extensions, while the ones in Debian do not.  Please
consider including my patch below which simply disables SIMD on armhf,
avoiding the detection of NEON.

This patch should be a no-op with the current Debian buildds, and I
believe it would be the correct behaviour if Debian acquired new
buildds with NEON, as NEON is not a required feature for Debian's
armhf port.

Regards
Graham
