[gmx-users] compile problem gromacs 3.3

[Erik Lindahl]

Hi,

The last two errors are typos that gcc didn't complain about - they  
are now fixed in the release-3-3-patches branch.

The floating-point detection is a bit strange, though, since you're  
certainly on a IEEE754 system. Gromacs should compile anyway, but you  
won't be able to use e.g. the software square root. It's not enabled  
on Alpha by default, though, since the hardware one is faster.

Anyway - please send me a compressed version of the config.log file  
outside the list and I'll see if we can fix that detection for the  
future.

Cheers,

Erik
