I *need* to use shared libs (SDL & openGl libs) and I guess it's -shared switch which set that 'linking option'. Every time I use it (-shared) ANY program I'm trying to run gives 'Segmentation fault'...
you may need to use shared libs, but surely not _execute_ them. you will get undefined behaviour on most platforms if you try to execute a shared library. AFAIK, for shared lib compiled with "-shared", the linker defines a bogus entry point and hence execve() results in a segmentation fault. You'd have a problem, if you are getting segmentation fault for the executable which link your shared libraries. Is that the case ?

Actually, I have a problem :) I *need* to use shared libs (SDL & openGl libs) and I guess it's -shared switch which set that 'linking option'.
