hI, I apologize for late reply. The script you mentioned worked completely fine. I guess I was using different shell. Thanks a lot
You're welcome. Just one remark. When setting any CPPFLAGS or LDFLAGS it is often helpful to put this statements in the same command line before the call of ./configure. Though a properly generated configure script in the correct sense of autoconf, some other scripts seem to make trouble ( for example the MPlayer as I was told ) /Flo

I will be glad if you can help with this.I tried your procedure on my computer and the configure script finished without trouble. Are your sure using fftw**3** ? In case you use fftw2 you have to tell the script. Another problem can be that you set the enviroment variables in another shell window as you execute the configure script, because then CPPFLAGS and LDFLAGS are not present anymore. To be on the safe side put all in one line: ./configure --prefix=$HOME/gmx4 LDFLAGS=-L$HOME/fftw/lib CPPFLAGS=-I$HOME/fftw/include This command line should work for you, in case FFTW3 is located as you mentioned before. So try copy&paste and tell us over the mailing list what happend.

I have installed fftw3 both with double and single precision but I still get the error while configuration of GROMACS for default single precision. I have also included the libraries usinG CPPFLAGS & LDFLAGS.If you have installed the single version of FFTW3 and supply the corresponding CPPFLAGS and LDFLAGS to configure then the script will find the libraries. So two errors are very likely though we do not anything about your installation: * a small typo in the configure line ( if you present it here, everybody can judge this ) * the installation of the single precision fftw3f failed for any reasons FloAny help will be appreciated _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
