I'm trying to compile FlightGear 0.9.10-pre3 on my PowerBook, but the installation of simgear fails while "make" with following error messages:

if g++ -DHAVE_CONFIG_H -I. -I. -I../../simgear -I../..  -I/FlightGear/include  -g -O2 -D_REENTRANT -MT visual_enviro.o -MD -MP -MF ".deps/visual_enviro.Tpo" -c -o visual_enviro.o visual_enviro.cxx; \

then mv -f ".deps/visual_enviro.Tpo" ".deps/visual_enviro.Po"; else rm -f ".deps/visual_enviro.Tpo"; exit 1; fi

I'm using Mac OS X.4.6 and Xcode 2.2.1. What am I doing wrong? What I need to do to finish building simgear and FlightGear on my machine? I'm a not so experienced programmer, or exactly, it's almost my first try to build a programm from source :-).

Can you please help me?


Ah, this is due to the render-texture code for OS-X code that was patched into SimGear; I had to fix an include to make it build, I'll send the (minor) patch for that to Erik once I get home; basically you need to pull in <OpenGL/CGLTypes.h> at the top of the file. The bigger problem is, the RenderTexture code doesn't work, and worse, is resetting the active GLContext to NULL when it fails, so I was getting errors from PLIB about no context being active during startup. I disabled the RenderTexture code in my local tree by adding an early return to the initialise() method.

If you just want to fly, you can try the binary I posted yesterday, of course (works on PPC Tiger and Panther, but crashes under Rosetta)
