Thanks Lenard,
I have it compiling and linking and everything. However, the windows and the
linux versions require very different library linking. So right now I've got
two separate lines in Setup.in, one that is for windows, and one that is for
Linux. Just comment or decomment them. The problem, however, is, is there a
way to have the ./configure selectively use one line or the other?
I also ran into a problem executing my module, once compiled and linked
together correctly:
0 [main] us 0 open_stackdumpfile: Dumping stack trace to us.stackdump
Traceback (most recent call last):
File "movie_test.py", line 7, in <module>
import pygame._movie as movie
ImportError: DLL load failed: Invalid access to memory location.
I'm going to do a bunch of documentation updates, and then turn back to the
windows functionality. I don't think I'll get it(windows port) in time for
the pencils down deadline on monday. At the very least, it will be an alpha
release.
Sorry guys, I overestimated the difficulty of the project. I will do what I
can over the next school semester to get it to a much more capable and
stable state.
