GFourier has only been tested under Linux 2.2, GTK+ 1.2 and Gimp 1.2; reports of tests and patches for other systems will be welcomed.
First of all, uncompress GFourier using tar:
Then, compile and install GFourier using:
The configure script provided has several options that are specific to GFourier:
--enable-debug: If GFourier is compiled with this option, it will produce debugging messages.
--enable-admin_install: Use this option if you want to install GFourier in a system-wide directory, and it will be automatically available to all the users in the system. You must be root to use this option.
--enable-fftw: This and other FFTW-related options are explained in the GFourier and FFTW page.
Now, you should be able to see a Fourier entry under the /Filters/Enhance/ menu (remember to restart GIMP, if it was already running). Go to the Instructions page to learn about how to use GFourier.
If the configure script fails, change to the src directory
and try the Makefile.orig file provided. You may need to edit it,
if you want to change the default options. Then rename it to Makefile
and do make install.
