compile question: mingw64 gcc 8.1.0 windows libretro #111

Closed ghost closed 5 years ago

ghost commented 6 years ago

Hi, when I compile 32/64-bit, everything works except one spot. ../build/obj/../Core/gb_libretro.c.o:gb.c:(.text+0xcb2): undefined reference to `random'

I did this in gb.c which isn't perchance a smooth idea, but I do get a 88.0 KB dll now and core works great.

ifndef random

define random rand

endif

For future self-compiling, what'd be a better way of avoiding that dangling undefinied reference?

LIJI32 commented 6 years ago

I'll probably just replace random with rand entirely, since it causes problems for some other libretro targets as well.

ghost commented 6 years ago

Maybe this could work since it only affects libretro?

#ifdef __LIBRETRO__
#define random rand
#endif

Something else I've wondered about is libretro/Makefile. Instead of relying on od and hexdump, would it be more portable/simpler to compile and run your own libretro/hexdump.c that does a plain fopen,fread,printf loop?

cremno commented 6 years ago

srandom() is never called except in Hexfiend's code. Is not seeding the PRNG intended?

LIJI32 commented 6 years ago

I didn't really think it mattered if it was deterministic for the first instance, but I guess I should add a __attribute__((constructor)) function to seed it.

I'm not sure how libretro's build system works for all different platforms it supports. Since it's more often than not cross-compiling, the build system should be able to build to both the target and the host at once, and I'm not sure the build system actually supports that. rgbds is a far heavier dependency anyway.

ofry commented 5 years ago

This still happens in latest master.

For libretro we build from the libretro fork, buildbot branch with the makefile inside the libretro folder.

ofry commented 5 years ago

But if there is libretro makefile, I think it should work? ^^
