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.
With "quite unsual" I mean how can I pass the va_list since the
objc_msg_lookup only takes two arguments.

Subject: Re: linking tool to use a framework : obj_send_msg error
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!
