Trying to compile Mednafen

Hello. I’m trying to compile a recent version of Mednafen (1.21). The configure script ends without issue, but when compile the source, I get this error:

There is an issue with POSIX compatibility?

I also tried the mednafen recipe from HaikuPorts, but that is an old one, and anyways appears to be broken too.

Both Haiku and Mednafen try to define a type called int32 (which is not in POSIX, it’s in BeOS. Posix and modern C use int32_t).

Adding a #ifndef __HAIKU__ around the typedef uint32_t uint32; in include/mednafen/types.h line 73 should fix this (then it will use the already existing int32 definition).

There is already a mednafen recipe that does all this, right?

Hi. I check the patches at HaikuPorts, but apparently don’t include the Pulkomandy fix:
https://github.com/haikuports/haikuports/tree/master/app-emulation/mednafen/patches

I guess is because the recipe is for an older version of Mednafen.

Haikuports devs already working on the new PR for Mednafen 1.22.1
See: https://github.com/haikuports/haikuports/pull/3765
