[Cs-dev] error from libpd csoundapi~ library files after moving CsoundLib.framework

Subject[Cs-dev] error from libpd csoundapi~ library files after moving CsoundLib.framework
AttachmentsNone  None  
In the process of building an app on Mac OS 10.8 with csoundapi~ (v5.2) embedded in libpd in a c++ project.

Everything works fine when the CsoundLib.framework is in the /Library/Frameworks folder.

But I wanted to package the framework with the app contents. We set xCode to copy the framework into the app contents - and set the new path in the framework using install_name_tool. That all worked fine.

Initially had an error from Pd (csoundap~) that it couldn't find the plugin directory, but we set the OPCODEDIR environment variable and that went away.

Now we're getting a string of error messages for each .dylib file in the Framework - even though these files exist in the OPCODEDIR path - and can be seen by the c++ program. And sadly no sound is being produced.  

Would be grateful for any suggestions. Thanks.

Tom

The error messages indicate Csound tried to load the plugins and could not, but this does not necessarily have to stop csound from working, what other messages are you getting?

I wonder if the plugins have a dependency that is not being found (libsndfile maybe?). If you run 

otool -L  

you can check for dependencies.

Hi Victor,

Yes that is what is going on. otool revealed that the internal .dylib files
for the plugins in the framework are still trying to run from
/Library/Frameworks - (which I had temporarily disabled for testing).  So
that probably means that we'll need to do more configuration. 

Or I'm wondering if you would suggest running it from a static lib? And if
there are any already compiled for Mac Os?  (Always looking for the lazy
solution)

thanks,

Tom
