Hi, I found the problem. HP linker default linkinge ist dynamic and it try to link main.o with libstdc++.sl. However the installed shared version of libstdc++ does not go with the installed gcc version. (latest installed gcc was configured with "--disable-shared") After forcing a static linking (with -aarchive,-lstdc++) all was fine.
