I found a solution by means of symbolic links (ln -s) between
directories "/usr/lib" where the lapack and blas libraries should be and
"/usr/lib64" where they are:

ln -s /usr/lib64/liblapack.so.3 /usr/lib/liblapack.so
ln -s /usr/lib64/libblas.so.3 /usr/lib/libblas.so

ln -s /usr/lib/liblapackpp.so.14 /usr/lib64/liblapackpp.so.14

and also by adding "-llapack -lblas" in my build command.


Thank you four your answer.

Guilhem.
