The effort was multi-person, but I did much of the original  
programming for USRP/FUSB and gr-audio-osx interfaces under 10.4 PPC  
in late 2005; the code was integrated with the trunk in spring 2006,  
and bugs have been fixed multiple times over since then.  Others have  
contributed programming / fixes for updating to Intel-Mac, 10.5, and  
10.6, as well as some of the cpu-specific blocks (e.g., FIR) and  
'missing' functionality (e.g., posix_memalign).  Most of GNU Radio's  
programming "just works" under OSX without modification: both Linux  
and OSX provide a POSIX-compliant API, which is generally pretty  
consistent between them.

Not sure what you're asking for here.  Maybe Josh knows better?

I can say that LIBSDL's .pc file is broken when installing under (at  
least) MacPorts (if not OSX in general, and maybe other OSs as well?):  
the "shared libraries" listing includes some static ones, and the  
static listing includes include some dynamic ones.  You might want to  
see if anyone has submitted a bug report to the MacPorts folks on this  
one, or even the LIBSDL folks might have a bug on this issue.  It does  
need to get resolved in order to gr-video-sdl to behave well on OSX --  
but if LIBSDL works on OSX, then it's not difficult to hack the  
Makefile to fix the issue & get something working (that said, I've  
never tried SDL to see if it really works on OSX; all I know is that  
it compiles, installs, and can be linked to properly).

I hope this provides some of the info you were looking for.  If not,  
ask more. - MLD
