I have been building my own updates for some time but have not hit a snag with Cycles being added to the trunk.
I created a new download repository according to the wiki for linux scons which includes the precompiled packages for boost and openimage. http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Linux/Ubuntu/Scons
I am now, however, getting the errors on building
/usr/bin/ld: cannot find -lboost_filesystem-mt
/usr/bin/ld: cannot find -lboost_regex-mt
/usr/bin/ld: cannot find -lboost_system-mt
/usr/bin/ld: cannot find -lboost_thread-mt
collect2: ld returned 1 exit status
I am lost!!!
