Dear Lammps user’s
i have tried to install the new recent lammps version on my cygwin using mpi and fftw however when i have executed the command make cygwin the package compilation start anf after time the run was stoped with error message
the error message was:
mpicxx -O -DLAMMPS_GZIP -DMPICH_SKIP_MPICXX -c …/msm_cg.cpp

cygwin is 32-bit only, right? so you should use -DLAMMPS_SMALLSMALL.
there is no gain (only loss) from even trying to compile in 64-bit
integers.
btw: up-to-date precompiled windows binaries (using mingw cross
compilers) are available from here:
http://git.icms.temple.edu/rpm/windows.html and according to paul
crozier, they are significantly faster than the ones compile with
cygwin. on top of that, mingw fully supports 64-bit.
