Attempting to compile on OSX fails as follows:

Ah, i didn't even realize it didn't find nproc at the top. I tried just make, make -j2, and make -j$(sysctl -n hw.physicalcpu). All fail in a similar manner and dont complete the build.

gingerbeardman commented 4 years ago

I believe it fails because this code uses modern C++ features

So, changing: https://github.com/Jakz/retro8/blob/96e26e7b7052e23e04682661b6ad7760e72966dc/Makefile#L140-L141

To:

 CFLAGS   += -Wall -D__LIBRETRO__ $(fpic) $(INCFLAGS) -stdlib=libc++ -std=gnu++11
 CXXFLAGS += -Wall -D__LIBRETRO__ $(fpic) $(INCFLAGS) -stdlib=libc++ -std=gnu++11

...gets us down to only 3 errors:

src/vm/lua_bridge.cpp:677:36: error: unexpected type name 'data_t': expected expression
    lua_pushnumber(L, std::bit_not<data_t>()(a));
                                   ^
src/vm/lua_bridge.cpp:677:28: error: no member named 'bit_not' in namespace 'std'
    lua_pushnumber(L, std::bit_not<data_t>()(a));
                      ~~~~~^
src/vm/lua_bridge.cpp:677:44: error: expected expression
    lua_pushnumber(L, std::bit_not<data_t>()(a));
                                           ^

Almost there!

And it compiles!

Though there appear to be some issues, compare these to this repo readme:

Jakz commented 4 years ago

I added a Xcode project that you can try with SDL back-end standalone to check if it's an issue with RetroArch core or with emulation in general.

gingerbeardman commented 4 years ago

I do not have libSDL2.abut rather SDL2.framework and building against that I cannot get it to launch:

$ ./retro8 api.p8 
Using renderer pixel format: SDL_PIXELFORMAT_ARGB8888
Error on lua_pcall on init
attempt to get length of a nil value

and no screen appears.

Jakz commented 4 years ago

yes I'm using the brew supplied SDL2 to use standard paths instead of shipping the repository with the framework.

gingerbeardman commented 4 years ago

I have brew SDL2 installed but Xcode couldn't find libSDL2.a

leolobato commented 4 years ago

@Jakz I've create a pull request that fixes linking to SDL2. It was pointing to a specific relative path on your machine before.

I was able to build and run it using my fork.

Jakz commented 4 years ago

👍 I close the issue then, thanks for fixes!
