kit-libs-osx

Statically-build libraries for games (OSX version).

Includes:

• SDL (a rather stripped-down build)
• glm
• libpng + zlib

All built using build.py.

Using

Clone this directory as a subdirectory of whatever you are building. Then add compiler/linker arguments as follows:

KIT_LIBS = kit-libs-osx

#for zlib:
C++FLAGS += -I$(KIT_LIBS)/zlib/include
LINKLIBS += -L$(KIT_LIBS)/zlib/lib -lz

#for libpng: (note: requires zlib LINKLIBS)
C++FLAGS += -I$(KIT_LIBS)/libpng/include
LINKLIBS += -L$(KIT_LIBS)/libpng/lib -lpng

#for SDL2:
C++FLAGS += `$(KIT_LIBS)/SDL2/bin/sdl2-config --cflags`
LINKLIBS += `$(KIT_LIBS)/SDL2/bin/sdl2-config --static-libs` -framework OpenGL

#for glm:
C++FLAGS += -I$(KIT_LIBS)/glm/include

(Note: this is Jam-like syntax; for Make, the variables are CXXFLAGS and LDLIBS.)

Notes/Caveats

The build.py script hardcodes all library versions except glm, for which it fetches the latest version from git.

If you are maintaining a project that you want to build against local libraries only if they exist, you can simply place the -I and -L paths for kit-libs before the paths for the system libraries.

For SDL you can modify the PATH environment variable in your back-quoted config calls:

`PATH=$(KIT_LIBS)/SDL2/bin:$PATH sdl2-config --cflags`

Alternatively, you can use shell tests on all options:

`if [ -d kit-libs-osx ]; then echo '-Ikit-libs-osx/...'; else echo '-I/usr/local/...'; fi`

This can avoid some warnings about non-existent paths from the linker.
