I use pv3 with offscreen rendering regularly, but I do not use
Mangled-mesa.<br>
Just set VTK_USE_OFFSCREEN,<br>
VTK_OSMESA_HAS_OFFSCREEN (can't remember the exact names)<br>
and point all the opengl stuff to <br>
/opt/Mesa-6.4.2/...<br>
<br>
using mangled mesa is (AFAIK) only useful if you are linking with both
normal GL and mesa GL at the same time (to avoid name conflicts), if
you only want off screen, then all you are doing is making things harder<br>
<br>
When compiled remember to use<br>
pvserver --use-offscreen-rendering (to avoid the X Display can't find
etc errors)<br>

<br>
I am trying to compile ParaView 3 with support for off-screen
rendering. I use Mesa 6.4.2 and a CVS version of ParaView3 that is
about 3 days old. I have compiled the mangled mesa. In ccmake, I have
set:<br>
<br>
MANGLED_MESA_INCLUDE_DIR /opt/Mesa-6.4.2/include<br>
MANGLED_MESA_LIBRARY /opt/Mesa-6.4.2/lib/libMGL.a<br>
MANGLED_OSMESA_INCLUDE_DIR /opt/Mesa-6.4.2/include<br>
MANGLED_OSMESA_LIBRARY /opt/Mesa-
6.4.2/lib/libMOSMesa.a<br>
VTK_USE_MANGLED_MESA ON<br>
<br>
Some compilation errors arise:<br>

Can somebody please help me? Is it still possible to use offscreen
rendering with ParaView?
<br>
<br>
Many thanks,<br>
