Re: [Monetdb-developers] why open() before dlopen()?

Also portability over all platforms is point of concern, there is some old old out there, e.g. HP-UX.
Ok, then I'll make the patch specific to OpenBSD unless someone here has a preferred solution. Thanks, m

Well, you haven't shown us your patch, but in general dlopen is a very smart function, that does things like adding the right extension for the platform at hand, so in general one should try hard to benefit from it's -- sometimes really just black -- "magic".

The issue isn't with dlopen(). It's with MSP_locate_file() in mal_linker.c. MSP_locate_file() throws a runtime error if open() fails, and the call to open() assumes a .so with no version suffix. This logic assumes a certain setting of the libtool variable library_names_spec, which can vary by platform. In fact, there's already an #ifdef _AIX in that function that ignores the open() error, so this has come up before for another platform. Thanks, m
