I've submitted this as a bug report in the bug tracker system on the Gna! relax site. Attached to the bug report is an archive containing all the files necessary for testing the relaxation curve-fitting C module. Between the 1.2.2 and 1.2.3 releases, I specifically removed the -fPIC option in the Sconstruct script (which is only added as an option when the gcc compiler is used). The reason was that when using the -fPIC compilation option, the shared object relax/maths_functions/relax_fit.so would compile but would segfault during execution. My system is Mandriva 2006 and, hence, the problem may only arise in that distro. Chris, if you have time, would you be able to run relax on the files I've attached to the bug tracker? It would be much appreciated. If you use the 1.2.2 release or the 1.2.3 release with the option 'SHCCFLAGS' removed from the 'sconstruct' script, the information of whether the module segfaults on SUSE 10 would be useful in fixing the problem. Another useful test would be to compile the module by hand by typing:
$ gcc -I/usr/include/python2.4 -c -o maths_fns/c_chi2.os maths_fns/c_chi2.c $ gcc -I/usr/include/python2.4 -c -o maths_fns/exponential.os maths_fns/exponential.c $ gcc -I/usr/include/python2.4 -c -o maths_fns/relax_fit.os maths_fns/relax_fit.c $ gcc -shared -o maths_fns/relax_fit.so maths_fns/c_chi2.os maths_fns/exponential.os maths_fns/relax_fit.os then running the test files, re-typing these commands with the -fPIC option, and re-running the test files.
