[osg-users] Please test OpenSceneGraph master in prep for 3.5.6 dev release

[Li Chi]

Hi Osfield,

I make a series of tests, and maybe the cause of the problem is this:

In a c++ program:

#define OSG_GL_FIXED_FUNCTION_AVAILABLE
#if defined(OSG_GL_FIXED_FUNCTION_AVAILABLE)	// <== this line returns true

but if you write like the following lines:

#define OSG_GL_FIXED_FUNCTION_AVAILABLE
#define FIXED_FUNCTION defined(OSG_GL_FIXED_FUNCTION_AVAILABLE)
#if !FIXED_FUNCTION								// <== this line returns true (wrong)

so, I think '#if defined(...)' or ''#if !defined(...)'' must be used in one line (must be used together), as least MSVC++ is doing so.


Thank you!

Cheers,
Li
