VMS Installation Notes

Bernd Ulmann has graciously created a page containing FFTW installation instructions for OpenVMS, as well as a prepackaged version.

Another patch file for OpenVMS is posted at Jouk J.'s web page, including support for FFTW 3.0.

The following notes were for FFTW 1.2, and are not applicable to later versions of FFTW. We leave them here for historical purposes. (You will probably need to create your own Makefile; see the section of the FFTW manual on installation on non-Unix systems.)

Jouk Jansen sent us his changes to get FFTW 1.2 running under VMS.

To get fftw_test working, he copied GETOPT.C from http://www.openvms.digital.com/cd/UUDECODE/SRC.

He also made the following changes to FFTW files:
