Hello
First of all, sorry if my english its not very goods since its not my native languaje. I need to modify some GCompris activies and install them on a xo-1 with
Build number:852       Sugar: 0.84.16     Firmware : Q2E45
because the teachers dont like all the activities as they are, there are some activities that are easy to modify because i can do the changes with gcompris administration, like GCompris MissingLetter, but for the others i need to recompile them.  I made changes on several, like MemoryEnumerate, AlgebraGuesscount, Babymatch and others, then i run gcompris, and all the changes are there, the activities work as intended but when i try to install them on the xo, they dont start, i dont even get the

Cannot find cached 0sugar-launch implementation. or another error  (i know a workaround for the 0sugar-launch imlmentation error, i get this error with version 13 of activities mostly, all version 12 activities run perfect in the xo

the icon appears then afther a while the activitie close, i tried using the  ./bundleit.sh and  using setup.py, tried using GCompris 9.5 then Gcompris 9.3 (modifying the source files from the activities that come in that GCompris version)
So my question is, someone knows how to compile and install a modified GCompris activity in this xo?, really need help plz, im suposed to have them installed and working on the xo next week.
sorry for the inconvenience
thx, bye
