Hi, Gregor.

I reply you also on the CLAM mailing list. If you have to solve any other CLAM related issue i suggest you to subscribe to it from the CLAM web page.

The problem is that CLAM still uses fftw2 which is source incompatible with the one you are trying to compile: fftw3.

We are planning to migrate fftw3 some time soon as it is faster and more acurate, but we do not have any schedule for that.

So, the solution to your problem: Install fftw 2 instead. There are some packages available on the standard OpenSuSe package repository. So you should be able install it just by using YaST.


Please, report us any other problem or success.

BTW, the CLAM features shown on the ACM-MM demo and on the development screenshots have been not published yet. So if you are looking for them, please don't get dissapointed ;-) We can publish a development source snapshot if you want to try it.
