Hi,
I eventually abandoned my tries to use GL3. As I stated before, at the time I
tried to use it (under Windows) my conclusion was that the file osg/GL needs
some fixing to work under Windows. I don't know what the state is now (I was
using 2.9.9).
Cheers,
Florian

Hi,
I am getting compile errors with VS 2008, e.g. a define min conflicts with
the line:
Code:
if (fabs(length2) = std::numeric_limitsdouble::min())
in Matrix_implemenation.cpp.
The define comes from Windows SDK 7.1 WinDef.h that looks like this:
Code:
#ifndef NOMINMAX
#ifndef max
Hi,
I just figured there's more problems because of gl3.h including windows.h, well
at least the one I am trying to use, which is
http://www.opengl.org/registry/api/gl3.h
It includes windows.h if APIENTRY is not defined.
The relevant portion of (my) gl3.h reads:
Code:
#if defined(_WIN32)
Hi Peter,
As Paul mentions, as you've found out the hard way, right now you have
to set the flags all manually to disable/enable the appropriate parts
of the OSG to build against the different GL targets.
My plan has been to test out the ports as flexible as possible -
trying out GLES paths on

It'd be nice if selecting the OSG_GL3_AVAILABLE CMake variable would

Just for the search function :)
If you get errors like this:
error C2039: 'glBegin' : is not a member of '`global namespace''
error C3861: 'glBegin': identifier not found
error C2039: 'glEnd' : is not a member of '`global namespace''
error C3861: 'glEnd': identifier not found
turn off

Hi Robert and Paul,
Thank you both for your replies. Your answers affirmed my own investigations
into gl3.
For Paul - my OSG project is being developed for Win32 x64. I have just moved
it to Windows 7 x64. It is tied to Windows because it is designed to work in
concert with other Windows
Hi John,
I haven't tried GL3 yet - this work was done by Paul Martz, but I did
the GLES work which served as ground work for the GL3 support so I'll

Hi Robert,
Thank you again for taking the time to reply. Your assumptions were correct, I
had not turned off the other GL options.
I am planning to play with gl3 a little, there must be some advantages to using
it. But it also seems at first glance that one might be giving up some
Hi,
My nVidia graphics driver supports GL 3.2. So I enabled OSG_GL3_AVAILABLE and
got hundreds of errors about gl3.h. I downloaded gl3.h from OpenGL.org and
placed it where it would be found, and got hundreds of new errors.
I know I am doing something wrong and was wondering if someone would
