I wonder if there might be another AXIS function that is within the IDL_PATH. Perhaps, you can try setting the IDL_PATH to the default setting using the following commands, and see if that helps: .f path = pref_get('idl_path') new_path = '' pref_set, 'idl_path', new_path, /commit path_cache, /rebuild Try running the example and see if it works. Then, enter the following command to return to the original path: pref_set, 'idl_path', old_path, /commit path_cache, /rebuild

Many thanks, that was exactly the case. Solar soft has also an axis.pro which was compiled instead. I solved the problem by forcing the compilation of the original axis.pro within a my_startup.pro
