[gmx-developers] GCC Versions

[Erik Lindahl]

Hi,

I'm considering switching the build system to CMake (in the short  
perspective we'd support both this and autoconf), so in that case we  
could do it through CTest and CDash. This way any user can do  
automated testing on their pet platform and report the results to the  
test dashboard, where it will show up in red if some tests break.

The original 4.1.x warning was due to a prerelease compiler shipping  
with Ubuntu, IIRC.

Cheers,

Erik
