Re: linking tool to use a framework : obj_send_msg error

[Thomas Kupper]

There is probably some 'optimisation' in the framework calling the Apple runtime message send function directly (the quotes because anything doing I/O like this is likely to gain an imperceptible performance increase from calling the runtime functions directly rather than using -methodForSelector:). Try grepping the source code for objc_msgSend() and, in files that contain it, add this macro:

#define objc_msgSend(theReceiver, theSelector, ...) \

objc_msg_lookup(theReceiver, theSelector)(theReceiver, theSelector, ## __VA_LIST__)

Perfect! That's exactly what causes the error. In one file there are three calls to objc_msgSend. Now I tried to define the macro you mentioned. Unfortunately the # __VA_LIST__ part is not recognized and Google wasn't any help, and neither was a find ... -exec fgrep ....

On the other hand, if there are only three calls to objc_msgSend in only one file I could maybe just replace these three calls. But the objc_msg_lookup calls seems to be quite unusal.

Would you mind helping my again? I tried to compile it under Ubuntu 8.10/Debian 5.0.

Thanks for excellent help!
