Probably not. I do not know much about linking etc., but now I tried

mkoctfile -l/usr/lib/libgsl.so -l/usr/lib/libgslcblas.so gsl_rand.cc

However, I get the error message

/usr/lib/gcc-lib/i586-suse-linux/3.3.5/../../../../i586-suse-linux/bin/ld:
cannot find -l/usr/lib/libgsl.so
collect2: ld returned 1 exit status

(although the two files exist in /usr/lib).

Any suggestions? Sorry to bother you again,


Michael.
