by including run_loop_cocoa.m in my own project, the problem has been resolved.

hi. thanks for reporting. Indeed, run_loop_cocoa.m is missing libBTstack.a but 
not in libBTstack.dylib. I'll try to fix that later.

Anyway, most BTstack app links against libBTstack.dylib. Do you use the static 
.a on purpose and can you tell me why? (You may respond in private to 
matthias.ringwald@gmail.com if you like)

funny. I forgot a rule to include any .m files for the static library. fixed in 
r965

Hi, libBtTstack.dylib could be replaced by other's version, I got a "WARNING: 
execute not available for RUN_LOOP_COCOA!" when there is an older version 
installed on the device.

for an POSIX environment, BTstack brings its own run loop. In a Cocoa(Touch) 
environment, it seamlessly integrates with the app's run loop (for UIKit apps). 
In that case, you only register all BTstack stuff and don't (need to) call 
run_loop_execute() - that's why I give a warning. 

In the latest SVN revision, run_loop_execute create another Cocoa run loop to 
keep the semantics.

Please discuss on the BTstack Google Group and not here.. these are for actual 
"Issues" of BTstack, not developer support.

I was not reporting a new issue in comment 4. I was saying why I choose to link 
againt static library.

oh. sorry, I didn't understand your comment. In such a case where you depend on 
a feauture/detail not in Cydia/BigBoss repository, I would suggest to urge me 
to release a newer version and use package dependencies.
