[PD] problems compiling pix_opencv in OSX (Was Re: pdp_opencv & pix_opencv new development)

[Jack]

Hello PD users,
When i compile opencv, i get this error on macos X.4.11, G4 powerbook :
../../../otherlibs/highgui/cvcap_qt.cpp: In function `int  
icvWriteFrame_QT(CvVideoWriter*, const IplImage*)':
../../../otherlibs/highgui/cvcap_qt.cpp:1183: warning: unused  
variable 'status'
../../../otherlibs/highgui/cvcap_qt.cpp: In function `CvVideoWriter*

make[3]: *** [cvcap_qt.lo] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Any idea ?
I followed the instructions from :
http://opencvlibrary.sourceforge.net/Mac_OS_X_OpenCV_Port
Thanx.
