Are you saying that code compiled with -fPIC is invalid? That sounds like a bug, but I couldn't see it in your e-mail. If that is the problem, please show us a small example with the generated assembly code. And don't forget to tell us which version of gcc you are using. Or are you saying that the code was not compiled with -fPIC, and therefore you can not use it in a shared library? If that is the problem, then the only option is to recompile it with -fPIC. There is no way to convert non-PIC into PIC after it has been compiled. Ian
