Mario -- you just staticly build-in GLEW, don't you? so I could just drop dependency on libglew altogether for that matlab- package, or I have forgotten smth?
Yes, statically linked, so dropping the dependency for the Matlab mex files from me should work.
Although i wonder why the same problem doesn't happen with your octave mex files? Dependency on different glew version - probably whatever is the system default one? My Ubuntu 14.04 has libglew1.10 as current one. I have an old libglew1.9, but that seems to be a leftover from a 13.04 installation and the package manager says it comes from: 1.9.0-3~bnd1~nd13.04+1
So at some point it was part of NeuroDebian, apparently for 13.04.
freenect -- would you mind rebuilding your extensions against freenect 0.2? for some reason I have only uploaded 0.2 to Debian proper but not to NeuroDebian, and now users on bleeding edge Ubuntu releases with neuroDebian end up "bleeding". Ella -- I will push a build of 0.1 version of libfreenect for trusty tomorrow to NeuroDebian so we would have a quick resolution for that one at least...
Not sure about that. Old distros which we still support won't have freenect 0.2, no? My old Matlab build system definitely doesn't have it.
I'd do such a switch for the next beta, when the 3.0.12 series starts, so we can have one transition with changed dependencies/system requirements. I'd like to avoid touching 3.0.11 as much as possible, i really want to get rid of its maintenance, given that it is declared eol since April.
But iirc one can simply set a soft-link from freenect 0.1 to 0.2, and the mex files will work with it and gain some new functionality, e.g., XBOX for Window support.
