OSX/X11 (i.e. ppc support)

I'm trying to get 0.4 working on OS X (again). I'm okay using the X11/gtk environment, but I'm having some problems running it. Here's what I've done to get it to compile:

- modify the SDL test and makefiles to use `sdl-config --cflags` and `sdl-config --libs` as apopriate
- remove #include <malloc.h> in a bunch of places
- comment out the x86 asm in r4300/x86/rjump.c - this is probably the cause of my problems, or the next one removing random code is not generally a good idea, I know, but I wanted to get it to compile
- copy a bunch of signal defines from some page on the internet into main/gui_gtk/main_gtk.c - OS X was missing a few, so I copied the whole lot from another OS, I think BSD... again, probably not a good idea, but I wanted it to compile

Well, the interface runs, and can load a ROM, but it crashes when I try to run it (yes, I expected that to happen!!! it actually got farther than I thought it would). Here's a transcript of me loading Mario 64 and trying to run it:

Code:

Couldn't read config file '/Users/josh/Desktop/emu64/.//gui_gtk.conf': No such file or directory

Signal number 4 caught:
	errno = 0 (Unknown error: 0)

My problems now:
- fixing the 3 lines of x86 asm in the whole project! They're all in r4300/x86/rjump.c
- finding the right header/defines for main/gui_gtk/main_gtk.c
- since the ROM loads sucessfully, I assume there are no endian issues... Flea got them fixed?

(To OS X users: there's really very little hope of this working, but I figured it was worth a shot.)

Thanks for any help or insight... and I apologize for any incoherentness in the above post... it's late.

Hey all,

I've been trying my hand on porting mupen64 to Mac OS X, and here are my results so far (thanks to information on this board, others, and other websites):

Completed:
- actually compile (Makefile changes, #includes and such)
- rjump.c from the old 0.3 Mac port
- GTK gui (I thought it much easier to use it than code my own)
- porting of the input plugin

Partially completed:
- Plugin loading support. I've figured out how to load symbols from other files with OSX "bundles" (because shared objects are not supported), but it does not work perfectly well: mupen64 gets the name of the plugin, but calls don't seem to work (nothing happens when the about button is clicked with the input plugin, which should bring up a GTK dialog box).

Still to do:
- glN64 plugin. I'll probably end up taking the code from the old Mac port.
- RSP plugin. same here.
- sound plugin. should be really easy; it's just a couple of SDL calls.

So the biggest barrier I see in getting this to work now is just figuring out what's not working with the plugin loading (and any endianness issues that are sure to come up). I'd love to collaborate with anybody else on this, if they want. I'll also post a patch of what I've done so far if there's interest.

Oh, and attached is a screenshot of the current behaviour.

Cheers!
