Re^3: Problem running FIREFLY on a 64-bit MPICH2 environment

Alex Granovsky


actually, most Linux distros uses /lib and /usr/lib for 32-bit stuff,
while /lib64 and /usr/lib64 for 64-bit ones. Debian is a little bit
specific here as it uses /lib and /usr/lib for 64-bit libs while
/lib32 and /usr/lib32 for 32-bit ones.
