LS, After successful compilation (using g++ -o testgsl testgsl.cc `/usr/bin/gsl-config --cflags --libs`), I get the following runtime error: ./testgsl: symbol lookup error: /usr/lib/libgsl.so.0: undefined symbol: cblas_daxpy
Using ldd -r /usr/lib/libgsl.so, I see that all cblas related symbols are undefined. Any help is appreciated! many thanks, Ernst-Jan PS. I'm using Ubuntu 11.10 on Linux 3.0.0-29-generic x86_64
