When I try -static with g++ on a hello, world program on GNU/Linux, the resulting program does work, in that it prints hello, world. I haven't tried running valgrind on it. If you find that -static gives you a completely unusable executable--one that doesn't work at all--then something may be wrong. I tried gcc 4.3.2 on Fedora Core 10 using glibc 2.9.3. Given that -static does work with simple executables, and given that the gcc driver does hardly anything with -static other than pass it to the linker, I think that gcc is behaving reasonably. It would be annoying for it to give an error. Ian
