[gmx-users] trouble with -DGMX_BUILD_OWN_FFTW, crashing in m4?

[Mark Abraham]

Yes, this is a known problem. A race condition with parallel make
exists between the gmxfftw build target and the things that depend on
it. AFAIK, a second call to make will Just Work. There are known ways
for GROMACS to solve this by controlling the dependency properly, but
the leading candidates either do not work at all with a specific CMake
minor release, or require more invasive restructuring then we will do
in 4.6 series. A long discussion thread exists on gmx-developers for
those with nothing to do!

Do let us know how you go. I guess we should update the install guide
accordingly.
