This may be the wrong list for this question (the links to mail archives
are still down, so I also couldn't search for previous messages).
I am compiling OpenSG 1.* from CVS. I haven't done this in a long time,
but we would like to port some software on to the Cal3D plugin. I am
doing this on an up-to-date Prism running Suse, which is relatively up
to date (it has OpenGL2.0 on it).
I get a problem is (truncated in an obvious way, and removing warnings)
g++ -ansi -use_readonly_const -ftemplate-depth-100 -fPIC -O2 -fPIC
-DOSG_WITH_GLUT -DOSG_WITH_JPG -DOSG_WITH_TIF -DOSG_WITH_PNG
-DOSG_WITH_GIF -D_GNU_SOURCE -D_OSG_HAVE_CONFIGURED_H_ -DOSG_BUILD_DLL

Source/System/Window/OSGFBOViewport.cpp: In member function `bool
osg::FBOViewport::checkFrameBufferStatus(osg::Window*)':
Source/System/Window/OSGFBOViewport.cpp:1215: error: `
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT' undeclared (first use this
function)
Source/System/Window/OSGFBOViewport.cpp:1215: error: (Each undeclared
identifier is reported only once for each function it appears in.)
scons: *** [Build/linux-gcc/Source/System/opt/OSGFBOViewport.os] Error 1
scons: building terminated because of errors.
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT is actually undefined on this
machine in glext.h (where GL_GLEXT_VERSION is 27).
The define guard around the statement is just:
#ifndef
GL_EXT_framebuffer_object
there must be a few more refinements that are needed there. This is
something I can easily hack around for testing purposes, but someone who
knows more about opengl extensions might be able to suggest the correct
factoring to go back in to CVS.
