<br>
Any feedback on that issue ? <br>
Is there something I need to change in my code to get OpenGL >

Hi all,<br>
<br>
I am trying to port my GNU/Linux project (with OSG 3.4.0) to OS X.
<br>
I first installed OSG with Macports. <br>
<br>
However the glsl shaders do not compile with anything above
version 110, whereas i need at least version 3 and when available
4.2 (for image load store features).<br>
<br>
I saw this post, which relates to the same issue (choosing OpenGL
Core Profile instead of Compatibility profile): <br>

href="http://forum.openscenegraph.org/viewtopic.php?t=9992&highlight=osx">http://forum.openscenegraph.org/viewtopic.php?t=9992&highlight=osx</a><br>
<br>
It would seem that the issue has been fixed, but looking at the
source code of OSG 3.4.0, 3.5.0 and 3.5.1, it does not seem that
the correct calls have been added. <br>
I tried adding them before recompiling OSG but then i get a bunch
of errors.<br>
<br>
If i change the shaders syntax and use version 110, in order to
match compatibility profile on OSX, they compile but the
application then crashes.<br>
Here is backtrace of the crash :<br>

<br>
Is there something specific I need to do in my code in order to
activate the OpenGL Core Profile ?<br>
<br>
<br>
Thanks in advance,<br>
