Request: libsdl2-framework

[mf2k (Frank Schima)]

I am requesting a new port that installs the Framework build of SDL2. The SDL2 homepage ​briefly mentions it without specifying how to build it that way. I will try to investigate soon. Hopefully it is just a configure switch.

With the exception of the docs, it should not conflict with the existing libsdl2 port. I am thinking that adding a non-default docs variant to libsdl2-framework should allow both to co-exist peacefully.

I am attempting to create a Portfile for ​Mame, which appears to need the Framework version of SDL2.

Cc'ing the maintainer of libsdl2 for possible comment.

Mame appears to have a USE_LIBSDL option which will make it use a non-framework version of SDL.

In general a framework build of SDL2 may not be that useful, since you'll likely have to patch in a -F${frameworks_dir} somewhere to make anything use it, and if you're doing that, you might as well change -framework SDL2 to -L${prefix}/lib -lSDL2 instead.

I have so far not managed to get that to work and use the Macports libsdl2 installation. I have set it to 1 (the default) and 0 but it keeps not finding SDL.H. I have also tried setting:

# SDL_INSTALL_ROOT = /opt/local/include/SDL2

If you set SDL_INSTALL_ROOT then it should be set to ${prefix}. But if you don't set that it's supposed to use pkgconfig to find sdl2. Can you share your Portfile?

There appears to be a bug in their build script: ​https://github.com/mamedev/mame/blob/master/scripts/src/osd/sdl_cfg.lua#L89

That seems to be trying to change e.g. -I/opt/local/include/SDL2 to -I/opt/local/include, but it's only removing /SDL and leaving the 2.

So far, I have only been manually modifying the makefile and building by hand. I have not started an actual Portfile yet.

Here is my mame Portfile attempt. #54699.

This is no longer needed - by me anyway.
