Build not working on MacOSX with brew

[KanedaFr]

I was unable to make it works with -framework SDL2 using raw GCC I don't know if it works with XCode but on CLI, no way to do it

To make it works with brew, i had to

• brew install libpng
• brew install sdl2
• update src/Makefile ifeq ($(name),Darwin) INCPATH = ../include -I/usr/local/include/ LIBS = -lpng -lz -lc BIN = libTilengine.dylib LDFLAGS = -dynamiclib $(shell /usr/local/bin/sdl2-config --libs) LIBPATH = /usr/local/lib/ endif .... CFLAGS += -I$(INCPATH) $(shell /usr/local/bin/sdl2-config --cflags) -std=c99 -O2 -fpic - DLIB_EXPORTS .... $(BIN): $(OBJECTS) $(CC) -shared $(OBJECTS) -o $(BIN) $(LIBS) $(LDFLAGS) -fvisibility=hidden

nothing on samples/makefile because path to user/local/xxx is already there

Hi! I don't know why it doesn't work for you, how your environment is setup. I have little knowledge on apple platform, but AFAIK gcc is not available, everything points to using CLI for XCode, and framework facility is Apple specific, not gcc, that's why it doesn't work. So brew is not required, just use CLI for XCode and SDL2 framework, and it should build. This is how I produce the binaries for itch.io. Let me know.

Hi,

I was unsuccessful at building Tilengine with CLI for XCode and SDL2 Framework. ("SDL2 framework not found" while I installed it from SDL2 package at SDL.org). I already met this problem because of the clang hidden behind CLI for XCode's gcc. Unable to fix it again, I moved to a way I'm using on some others projects : brew.

I saw you did it the same on samples/makefile, so I though it would be easier to use the same method on samples and lib.

If not needed, no problem :)

regards

Cheers for this! I had to make some further changes to my makefile but it worked. These are my differences.

ifeq ($(name),Darwin) INCPATH = ../include -I/usr/local/include/ LIBS = -lpng -lz -lc BIN = Tilengine.dylib #removed the 'lib' prefix as the install script wants to copy this filename. LDFLAGS = -dynamiclib $(shell /usr/local/bin/sdl2-config --libs) LIBPATH = ../lib/darwin_x86_64 endif
