[gmx-users] install gromacs 4.6.1 on 64bit Windows 7 cygwin

[Hua Lu]

Hi!
I got the following error message while compiling gromacs using a complete installation of Cygwin on 64bit windows 7. Any idea what the problem is?
This is what I have used to install as detailed on the gromacs website:

cd gromacs-4.6.1
mkdir build
cd build, cmake .. -DGMX_BUILD_OWN_FFTW=ON
make

the error occur at the last step 'make'


Thanks, Hua
