I'm creating a shared object library that uses Xerces-C++. I'd prefer to link my code to the static library (libxerces-c.a). However, when I try to do that, I get a link error: "relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC". (I've encountered this on Linux so far, but this is actually cross-platform code that will also run on Windows and Mac, so if there would be a similar problem on those platforms, please consider this bug to include them.) It appears that it is impossible to statically link a shared object against 64-bit code that is position dependent, since the shared object must contain only position-independent code. The static libraries can only be linked directly into an executable.
To fix this, I suggest that you please compile the static libraries for 64-bit Intel binary distributions such that they have position-independent code (the -fPIC option on gcc, as mentioned in the error above). Then it will be possible to link them either into an executable or into a shared object library. Thanks!
