PortAudio not initialized

[mc]

Wow, very interesting concept to run two similar languages in parallel, one untyped, one typed!

Yet, while trying to get xtempore installed and running on a mac 10.8.2,
i got stuck with initialising the audio device (see 'logs' below).

I had downloaded the xtempore executable from github as described lately in the blog
and used homebrew to get protaudio which installed version 19.20111121 just fine.

I also tried to compile xtempore from source, but ran in the expected problem building llvm 3.0.

Thanx for help or ideas about what might have gone wrong here,
mc


./extempore --print-devices

Could not open runtime/code.irPortAudio not initialized

[Andrew Sorensen]

The PortAudio not initialized message is a bit misleading here ;)  Portaudio looks like it's working fine.

The problem is actually with the "could not open runtime/code.ir" (that needs a line break ;-)

The extempore executable expects to find a runtime directory (which you can find as a toplevel src directory on github) in the current working directory.  This directory contains a bunch of runtime scm and xtm files that are loaded by extempore on startup.

If necessary you can override the location of runtime (i.e. put it somewhere other than the CWD) with the command line arg --runtime="pathtoruntime"

This is something we should have a more obvious/useful error message for - we'll get onto that.

Cheers,

Andrew.

Great, the arg '--runtime' lifted my break and did the trick!

Thanx for the quick response,
