[Opensim-dev] libgdiplus and OS X

[Diva Canto]

Yeah, I was having problems with libgdiplus on Mac OSX. After chasing 
the dependencies, this seems to be the story: libgdiplus has a 
dependency on X11's libXrender, which, in turn has dependencies on lots 
of other X11 libraries, namely: libXSM, libICE, libX11 and 
libfontconfig. On my defatult installation of X11, the .dylib's were not 
there. So I downloaded and compiled X11 to obtain those libraries (I 
didn't think of the CD! :-)

I was able to get rid of the errors on missing .dylib's, but in the 
process of doing this and trying things randomly, mono is complaining of 
missing .so's which completely confused me -- and result in uncaught 
exceptions, for which I had to patch the code. Since I have other 
servers running both Windows and Linux, and I don't love Mac OS enough, 
I sort of gave up on Mac. My Mac OpenSim is up and running at 
tagus.ics.uci.edu (authentication off, everyone welcome), but I won't be 
doing much more there. I've moved to Windows and Linux.
