Question

[potassiumiodide0990]

Hi! I want to work on gromacs on a windows based platform. I am trying to install fftw-3.3.3 using cygwin. But it is giving me an error when i use the configure command.

the commands i used were

$ cd /cygdrive/c/Packages/fftw-3.3.3
$ ./configure --prefix=/cygdrive/c/Packages/fftw-3.3.3 --enable-float

the error it is giving me is

./configure no such file or directory found

.

Please help

Well, it's pretty obvious.. you don't have a configure file in that directory, or it is not readable somehow.

Usually these libraries come with a README or INSTALL file that has detailed info on the installation process. Try checking there. FFTW is pretty straightforward to compile usually.

Also check that the configure script is executable: 'ls -l configure' should show 'x' flags. If not: chmod +x configure.
