Re: [Glsdk-devel] [GLM] development roadmap

[Branan R. <br...@gm...>]

Since error tolerance should be standard across all of GLSDK, I'm
explaining a way to do that. Ideally we should have a config.h that
has these sorts of things, but that's more involved. I'll add a
config.h template and instructins on how to add things to over the
weekend.

Add these lines to trunk/CMakeLists.txt, just above the chunk that sets -Wall:
SET(GLSDK_ERROR_TOLERANCE <default value> CACHE STRING "The error
tolerance for floating-point operations")
ADD_DEFINITIONS(-DGLSDK_ERROR_TOLERANCE=${GLSDK_ERROR_TOLERANCE})

In your glm header file, you should have a construct like this, just
in case it's used outside of our build system:
#ifdef GLSDK_ERROR_TOLERANCE
#define GLM_ERROR_TOLERANCE GLSDK_ERROR_TOLERANCE
#else
#define GLM_ERROR_TOLERANCE <default value>
#endif
