[Bf-committers] Mac OS X debug symbols with scons

[Richard Berry]

I'm trying to get a Mac build with debug symbols turned on. From the =
SConstruct file it looks as though this is done by changing BUILD_BINARY =
from "release" to "debug".

I had to do this manually by changing BUILD_BINARY in config.opts. It =
looks as though it isn't possible to set this from the command line =
because SConstruct always overwrites this with:
	config.write ("BUILD_BINARY =3D 'release'\n")

Something for the scons people to look at?



In the end, I wasn't able to get a version with symbols in it, although =
the application was larger (8 MB compared to 5.5 MB). It looks as though =
debug symbols are turned on for most of the calls to gcc (using -g) but =
the final invocation of gcc doesn't have -g turned on. Does this matter?

Does gcc require extra flags for debug symbols when using Shark / OpenGL =
Profiler?




Also, does changing BUILD_BINARY to "debug" cause extra debug statements, =
assertions tests etc.? The binary that I was using seemed much slower =
(also crashed a few times but this may be due to poking it with OpenGL =
Profiler). For profiling purposes I think it would be good to have a =
"debugsymbols" option for BUILD_BINARY which would be the same as =
"release" but with debug symbols turned on. Looks as though this wouldn't =
be too hard to do in scons...



Oh, the final call to gcc is:
