Re: [ESPResSo-users] installation problem on FFTW

[Tristan Bereau]

Hi Edward,

You might have to set some environment variables to let 'configure' know
where the FFTW libraries are. See the command "./configure --help" at
the bottom of the help message: variables "LDFLAGS", "LIBS", "CPPFLAGS."
(You probably only need to set one of them, but I can't remember which
one it is.) So first locate your fftw libraries on your computer and try
to add them to one of the variables. A bit of googling around might help.

Best,
Tristan
