If you want to help the port of Wine to OS/2, send me a message at <krynos@clic.net> I currently don't want beta testers. It must work before we can test it.
Here is what you need to (try to) compile Wine for OS/2:
EMX 0.9c (fix 2)
XFree86 3.2 OS/2 (with development libraries)
bash, gnu make, grep, tar, bison, flex
sed (a working copy of)
diff and patch are recommended
Lots of disk space (about 40-50 megs after EMX and XFree installed)
To compile:
$ sh
$ tools/make_os2.sh
$ make depend
$ make
$ emxbind wine
|
Currently:
configure and make depend work...
make compiles (with a modified Linux mman.h), but doesn't link.
signal handling is horrible... (if any)
EMX doesn't support mmap (and related), SysV IPC and stafs()
XFree86/OS2 3.2 doesn't support XShmQueryExtension() and XShmPixmapFormat() due to the same lack in EMX...
What needs to be redone:
LDT (using DosAllocSeg in memory/ldt.c) *
Implement mmap() and SysV IPC in EMX *
File functions,
I/O access (do it!),
Communication (modem),
Interrupt (if int unknown, call current RealMode one...),
Verify that everything is thread safe (how does Win95/NT handle multi-thread?),
Move X functions in some files (and make a wrapper, to use PM instead latter),
Return right CPU type,
Make winsock work
The good things:
OS/2 have DOS interrupts
OS/2 have I/O port access
OS/2 have multi-thread
Merlin have Open32 (to be used later...)
