Hi, Simple question, but the answer I cannot find. I have upgraded RH 6.2 to RH 7.0, which has gcc 2.96 but g++ still uses /usr/include/g++-2/ instead of /usr/include/g++-3/ How to use force g++ to use the new STL ? Is is faster than STL2 ? Thanks, -- Mark ==== vrossum@swallow.bio.brandeis.edu =====
