Do an OSX port about agsjoy

[vga-256]

Yup. Here's a guide:

testing how to build agsjoy for OSX

Go to:

https://libsdl.org/download-2.0.php

Download the latest stable release. Place in a folder (I placed in my_home/Dev), cd to it and do:

./configure
make
sudo make install

Right now I am having the error:

$ clang++ agsjoy.cpp -Wall -framework SDL2 -dynamiclib -o libagsjoy.dylib

ld: framework not found SDL2
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So I guess I didn’t correctly installed the SDL2 framework (ld: framework not found SDL2).

After downloading the development library of SDL2 (SDL2-2.0.8.dmg), opening it, and copying the SDL2.framework to /Library/Frameworks/ and doing the codesign codesign -f -s - SDL2 on /Library/Frameworks/SDL2.framework/ , it was possible to build using:

clang++ agsjoy.cpp -Wall -framework SDL2 -F /Library/Frameworks/ -dynamiclib -o libagsjoy.dylib 

with this, it was possible to generate the dylib : libagsjoy.dylib.zip

---

Only GetName should work because conflict with SDL_pollevent, see branch ags-sdl2-port-fix for fix.

---

Merged the branch in a default way to check for SDL initialization

[ericoporto]

A new and working libagsjoy.dylib has been added on the releases. I still don't know yet how to properly include the plugin in the MAC OSX port, but at least it should work.

@256colour , can you verify if it's working on MacOS ?
