I tried configure and use fftw2.1.5, all success, then I tried fftw3.1.2, with the same configure as I configured fftw2.1.5
./configure CC=“pgcc” CFLAGS="-O3 -fastsse -Mvect=sse -tp k8-64" F77=“pgf90” FFLAG="-O3 -tp k8-64" --prefix=/hptc_cluster/user_libs/fftw3.1.2
make
make install
then I used it with some errors:
$ make

==========
in fftw2.1.5 I can find those symbols defined, but not in fftw3.1.2, I tryed some more configures of fftw3.1.2, such as --enable-float, --enable-long-double…, all met the same errors with the application of turb f90 programs.
Will anybody help me out? Thanks very much!
