i have two separate installations of aolserver:
- one on macosx with the stuff from the first post and openacs (which is now up and running)
- the second is redhat 7.3, postgresql 7.2.3, aolserver 4beta10, nspostgres4beta1 (no openacs)
i was able to compile nspostgres4 on linux with no problems. on os x, however, i had to add the modlib flag russel mentioned.
i don't know if it would compile on one versus the other because of something operating system-specific, or because of the different versions of postgresql...?
