Hi,
I have some strange problems with running Blender from merwin-spacenav
branch. When I try to run it, then it prints following message and then
it crashes:
$ ../install/linux2/blender
ndof: dead zone set to 0.10
ndof: using SpaceNavigator
ndof: 2 buttons -> hex:3
found bundled
python:
/home/jirka/Development/Blender/svn/branches/merwin-spacenav/install/linux2/2.58/python
Fatal Python error: Py_Initialize: Unable to get the locale encoding
LookupError: no codec search functions registered: can't find encoding
Neúspěšně ukončen (SIGABRT) (core dumped [obraz paměti uložen])
Core file doesn't include anything useful :-/
When I tried to compile this branch without spnav support (my
user-config.py contains WITH_BF_NDOF = False), then linking of Blender
was ended with following errors:
/home/jirka/Development/Blender/svn/branches/merwin-spacenav/build/linux2/lib/libbf_intern_ghost.a(GHOST_NDOFManagerX11.o):

You forgot to add some #ifdef to source code files. I created patch that
enables to compile Blender without support of spnav at Linux. This patch
can be found in attachment. When I try to run Blender without spnav
support, then it crashes too:
