Thanks Max. Those were good write ups. I'm pleased to report that I've got
GHC hooked into Perl as a shared library (i.e., can call my GHC code from
Perl). I'm working on trying to get a reasonable build system solution now.
So far I've been trying to build a single shared library, but I thinking the
easiest/intended way might be to just get GHC to just build its own library
and then specify it as a required shared library to the Perl stub library.
This way I wouldn't have to mix flags from the build systems in the final link.
(although a shared library of stubs to a shared library seems a bit strange)
PS: Thanks to everyone responsible for getting shared libraries working.
