Hi, Just to give a sign of life and a bit of background on the cosmoe repository: *master* is the cosmoe-8d35 code drop *cosmoe-0.7.2* is the cosmoe-0.7.2 code drop It looks like the 0.7.2 code drop is much more functional, at least it is able to render a proper UI and such. This is what I got working on last BeGeistert. Please note, it has only seen working on Linux-32-bit (with SDL as output IIRC). The (Cosmoe) code is really messy, and lots of things to fix in there, besides indeed the Haiku code being _very_ old. I've started merging a cleaned up version of the Cosmoe code into a recent Haiku source tree, but this presents a lot of other challenges, so nothing visible yet. The main problem with recent Haiku code is that there is a lot more private sys calls being used, well, generally a lot more BeOS API usage then there was back then. Lots of more "conversion" code to write to get this even to buildable state. As usual RL and payed work is keeping me from moving fast on this :( In all honesty, I still think that starting a recent brach and reusing the Jam build system, maybe even hooking into the *_build target somehow, might be the best way to go.... Our "little" project (Haiku) has become to complex to really sensibly duplicate the whole build system IMHO... Not to mention the maintenance nightmare of keeping that up to date... Ithamar.
