Regarding the monkeys, I haven't played with this much but I'm wondering: if this is true, should it not also be true that one can only safely compile XS modules using the same compiler and settings that Perl itself was built with on one's machine?	[reply]

It's not that you have to use the same compiler, it's just more likely that you're going to have problems if you don't. Just be sure to have bribes handy for your local C guru and/or sysadmin to get them to lay hands on things when they break.	[reply]

So, are you telling me that if I have two vendors that I get libraries from and both will only give me the .so files and each choose to use a different compilier to build their product that I would not be able to use one installation of Perl to access them because I would have to choose one of those compiliers to build my Perl?

Maybe yes, maybe no. It all depends on the OS, the compiler used, the phase of the moon. You may get lucky and figure out what flags are causing `cc` to choke (`-fpic` is a `gcc`-ism for instance that's causing problems in your output below). It's even worse with C++ though (there's no standard for name mangling, for example, so two different compilers can make completely different symbols in the output object for the same `int foo( char *bar, double& baz )`.

I tried your suggestion and I do get lots of errors.
