Thoughts about building: (not yet anything about running) Not sure is this wiki updated for Lightspark 0.5.1: http://sourceforge.net/apps/trac/lig.../wiki/Building But Maemo5 doesn't yet have packages llvm-2.7-dev and xulrunner-dev. So port/package them first. (At least llvm is checked by cmake, not sure is xulrunner only for optional features) And Maemo has gcc4.2, but Lightspark needs GCC 4.4: https://github.com/lightspark/lights...eLists.txt#L53 I'm working on this to the extras-devel. EDIT llvm-2.7 (and llvm-2.9) needs newer gcc than 4.2. EDIT2 As posted in thread: http://talk.maemo.org/showthread.php?p=1102157 also libxml++ needs updating, Fremantle has 2.26.1-0, but 2.33.1 is needed. It seems that Ubuntu Natty's version is trivial to package to Fremantle.
