Hi, I don't have access to a Solaris box, but here are some suggestions.
There are two issues: ABI conformance and API performance. The intent of disabling macro wrappers is to ensure ABI conformance, so examine the generated OSG .so files to ensure no undesired platform-specific symbols are being referenced. Then there's an assessment of the impact on performance from disabling the wrapper macros. That depends on what GL APIs are affected by the macros (immediate-mode only, or others too?). OSG can select different render algorithms based on GL version/extensions/etc, so need to ensure those APIs are actually being measured. cheers -- mew > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:osg-users- > [EMAIL PROTECTED] On Behalf Of Andy Skinner > Sent: Wednesday, March 26, 2008 7:22 AM > To: OpenSceneGraph Users > Subject: Re: [osg-users] OpenGL API RE: Mac OpenGL integration / > CGLMacro.h > > I've build 2.3.6 on solaris with and without this define that disables > the macros. > > What are suggested examples to compare?
