I really > haven't paid any attention to that part. Sorry. > >Glad Hydrogen is working for you. > > Cheers, > Mark > Hi Mark, :) currently the rest of my gentoo system is banging my head... ; :) I did it the hard way: I threw away the installation of python-3.2 in /usr/local which I need to compile blender. Effect: Blender does no longer build. I removed all python installation from my system except of the one emerge uses. I did a revdep-rebuild -pv to see, what applications and libs depends on what version of python. I filtered out all package which looks like libs or things used by other programs and tried to build them against python 3.2: Some failed I reinstalled python all versions of python, which were needed from the dependencies shown by revdep rebuild. With eselect python I set it to python 2.7. I rebuild hydrogen, which wasn't confused by linux3 setting from out space (plan9, I think). Blender now builds and runs. The trick was, that the system wide python 3.2 (which blender needs) uses lib64 while the previously under /usr/local installed one uses lib as the directory where its own python code is store. I build blender by myself. The pure vanilla code, freshly taken from the developpers svn repository. No patch, no tweak. The real thing :) ;))) Unfortunately blender spit out messages, that it is built against libpng-1.2.27 ... and the whole systems only contains libpng-1.5*. Currently I have no clue, what the reasons fro this is. Unfortunately the CUDE renderer fails to do its job. I can start blender...but not really much more. This was a day in deep hack mode. Strace was my friend...as so often. Will see how I can fix the rest of the problems. The main problem of builing hydrogen was the python under /usr/local I think... Will see what hick up next Cheers, Meino

May your life be full of head banging drum riff all day & night long. Now, can you verify that the system wide python setting was in fact what made it build on your system? I know you were doing lots and lots of things. Was switching this back to 2.7 the thing that allowed Hydrogen to build for you? As for Blender I really don't know what to do as I've never run it. Are you building Blender from an overlay or standard portage? If it's standard portage, and if the ebuild maintainer hasn't specifically said that you have to use 3.x then should a bug report be filed? That may make no sense on other information you posted. I really haven't paid any attention to that part. Sorry. Glad Hydrogen is working for you. Cheers, Mark

TADA! ;) That is very nice ! :)) Thank you very much for all your help. Unfortunately the svn-build of blender builds, but the executable only prints: Fatal Python error: Py_Initialize: Unable to get the locale encoding LookupError: no codec search functions registered: can't find encoding [1]20570 abort blender -noaudio Does anyone has built a daily snapshot of the svn blender successfully against the systemwide python 3.2. ? How can I get blender to work? Cheers mcc
