Dear all, I am a new user of GROMACS and suffering from severe problem about fftw-3.2.2 installation. Actually I have installed cygwin on windows XP with gcc, gdb, and make packages rest all are leaved default. Now when I have used configure command then it would give last line as config.status: executing libtool commands then returned back to my current working directory, after that when used make command it gives an error i.e. ../libtool: line 111: CDPATH: command not found libtool: Version mismatch error. This is libtool 2.2.6 Debian-2.2.6a-4 but the > libtool: definition of this LT_INIT comes from an older release. > libtool: You should recreate aclocal.m4 with macros from libtool 2.2.6 > libtool: and run autoconf again. > make[2]: *** [align.lo] Error 63 > make[2]: Leaving directory `/cygdrive/c/fftw-3.2.2/kernel > make[1]: *** [all-recursive] Error 1 > make[1]: Leaving directory `/cygdrive/c/fftw-3.2.2/' > make: *** [all] Error 2 So friends I will be very thankful if anybody help me. with regards -- Pawan Kumar Raghav ___ gmx-users mailing listgmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
