thanks knudfi, it works :-)
about stlplus3, i have found out that the directory containers does not compile. Doing a little research i found (ggogle) that containers is a only-include library, so it is not necesary to compile it, but another link talks about libcontainers.a, so i am confused. In fact, i compiled stlplus3 in resealed mode, but i did found makefiles to do it as a monolitic library. Comments , advices :-) ????
