copied!<p>I had a problem compiling on Snow Leopard too, but was able to get it to work by following the instructions at: <a href="http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port" rel="nofollow noreferrer">http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port</a></p> <p>The only modification I had to make was also to disable ffmpeg inside of ccmake</p> <blockquote> <p>The GNU autotools methods (make && make install) are being outdated. Volunteers to edit this section?</p> <p>mkdir opencv/build cd opencv/build cmake .. ccmake .</p> <p>If you are on Snow Leopard, hit 't' to toggle advanced mode. Set CMAKE_CXX_COMPILER="/usr/bin/g++-4.0" and CMAKE_C_COMPILER="/usr/bin/gcc-4.0" and then continue with the following steps.</p> <p>Hit 'c' to configure. Hit 'g' to generate the config file and exit ccmake.</p> <p>make -j8 sudo make install</p> <p>If you hit the following build error:</p> <p>/Users/awagner/Developer/opencv2/src/highgui/grfmt_tiff.cpp:292: error: ‘fmtSignTiffII’ was not declared in this scope make[2]: <strong>* [src/highgui/CMakeFiles/highgui.dir/grfmt_tiff.o] Error 1 make<a href="http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port" rel="nofollow noreferrer">1</a>: *</strong> [src/highgui/CMakeFiles/highgui.dir/all] Error 2</p> <p>you can get the build to complete by commenting out line 292 of src/highgui/grfmt_tiff.cpp and running make again. (This probably breaks something in TIFF export, but the build at least completes)</p> </blockquote>
