Thanks Scott. Actually I have been following John Keiser's document as well. The code compiles fine and I get the appropriate output. However it doesn't tell me how I can load an so ( shared library ) . Any pointers on that ?
I guess i misunderstood -- are you wanting to load libraries at runtime or at link time?
Loading at link time is just a matter of adding -lfoo to link with libfoo.so.
Loading at runtime is rather more difficult, because code that uses dynamic libraries is not terribly portable. Also, C++ name mangling conventions make it more work to find C++ symbols than C ones, and you still have the problem of marshaling parameters (which compiled XS code does for you). Since perl extensions are already shared objects, you can save some grief by having a compiled XS extension that explicitly links with your target library, and load the extension on the fly with require.
Other gurus may have better info than i. -- elysse (pregnant): are your hands cold? me: uh, i suppose so. elysse: will you put them on me?
