Well I decided to take the plunge over the weekend. It was either that or paint a room at home :-) I spent part of the weekend porting PA to OS X and discovered much. PA now compiles on OS X And what a bugger that was! Now don't get your hopes to high and bear in mind I'd never seen PA before friday and I've still never seen it running on anything yet. It just happened to be something of interest as I want a low-latency cross platform rtp server on my mac (I was too lazy to boot my linux box and Darwin Streaming Server was too easy ;-) ) I have some draft instructions for doing a clean install and build as well as several patched/new files. I'll sort them out in a few days. The build should be consistent and repeatable on other systems. I discovered that my superficial aversion to autoconf etc and libtool is somewhat justified but I am getting my head around them after avoiding them for years. I also discovered some new rude words to say in Apple's general direction.... Most of my software development has been on Linux and Solaris. I've never had to write any significant system software on Darwin. So whilst this may be old news to many of you, I've just found out many of Darwin's non-posix/standard quirks. The challenges included: * All the POSIX semaphore functions are supported EXCEPT anonymous semaphores via sem_init(). Guess what PA uses %&*#@#!! So I've added a new sempahore-osx.c to handle that. * Darwin doesn't support the POSIX clock_get*() functions. Guess what PA sues *%$#)* So I've written high resolution clock_get*() equivalent functions. * PA scripts use preload etc to load modules - but Darwin treats shared libs and modules (bundles) as different species, so preload breaks. &%(#**&@#@! * linking in Apple frameworks Anyhow you get the idea :-) I don't claim the result does anything useful, but - hey - at least it runs a bit :-) Because it doesn't load all the modules at startup (for now anyway) here is my command line and some debug.

Probably reads EOF or bad fd. How 3) Yes I can see the modules are listed twice .... :-) cheers Kim
