Re: [Pingus-Devel] OSX Lion build help

[Andy Milne]

Yes, that change does work. It appears that it doesn't matter if Cocoa is added before or after  OpenGL.

And yes the 64bit build did work for me - thanks again for publishing it. I just thought it would be fun to see if I could build it myself on a Mac.

I had lots of problems building SDL 1.2 on Lion, and SDL 1.3 worked first try. That led me to porting pingus to SDL 1.3 - hmm, that's probably why I needed to link to Cocoa. So, you probably don't need that change - yet.

Don't get too excited about my port to SDL 1.3, my build doesn't run: I get a Segmentation fault: 11. The 1.3 changes are quite minor: surface objects need to call a method to get their alpha/color and the keyboard scan code stuff changed.

Meanwhile I found a fix for building SDL 1.2, I needed to add another parameter to ./configure:

--disable-assembly

I'm attempting to rebuild pingus with SDL 1.2, and my current problem is that scons is not seeing SDL_mixer. I was impressed to see that  scons generates a "c" program and attempts to build it to test for the presence of SDL_mixer. So, I'd have to agree that the scones build environment can't see SDL_mixer - even though I can see it. It's weird that I didn't have this issue before with SDL 1.3, but I'm sure I'll track it down and sort it out. 

Regards,

Andy.

I'll let Grumble fix this, but for a temp fix, I think you can edit the SConscript file

change line 152: self.conf.env.Append(LINKFLAGS = [ '-framework', 'OpenGL' ])

to self.conf.env.Append(LINKFLAGS = [ '-framework', 'OpenGL', '-framework', 'Cocoa'  ])

PS- tell me if this works

PS2-- doesn't the 64-bit build work for you?

Hi,

I followed the recipe Josh has on the Wiki to build pingus 0.7.6, except I'm using OSX 10.7.2. Thanks for the recipe - it really helped.

I'm at the linker stage and I can see that the following line:

g++ -o build/pingus -framework OpenGL build/src/main.o build/libpingus.a -L/usr/local/lib -lboost_signals -lpng15 -lSDL -lSDL_image -lSDL_mixer -liconv

really should be:

++ -o build/pingus -framework Cocoa -framework OpenGL build/src/main.o build/libpingus.a -L/usr/local/lib -lboost_signals -lpng15 -lSDL -lSDL_image -lSDL_mixer -liconv

Cocoa is required to pick up the missing symbols like CFBundleGetMainBundle() etc.. see error at the bottom if you're interested.

I'm not used to the tool chain for building pingus, and I figure you might be able to quickly point me in the right direction?

Thanks,

Andy.
