我爲mac OSX（Mavericks）下載了opencv 2.4.6。 Untared tar文件，並提出以下steps：在Mac上建立opencv 2.4.6 - 小牛

cd opencv-2.4.6.1/ 
mkdir build 
cd build/ 
cmake -G "Unix Makefiles" .. 
make -j8

但我得到一個錯誤在構建

與'make'，而不是'讓-j8'嘗試。我以前見過這會導致OpenCV出現問題。我知道，這很奇怪。 – karlphillip

我用cmake的這個編譯選項：

cmake -G "Unix Makefiles" -D CMAKE_INSTALL_PREFIX=/Users/produit/Library/Developer/opencv/ -D CMAKE_OSX_ARCHITECTURES=x86_64 -D BUILD_PERF_TESTS=OFF -D BUILD_opencv_legacy=NO ..

我有同樣的問題，像OP，這確實做了詭計，謝謝 – JonEasy

謝謝皮埃爾的這個提示。 – tuscland

很奇怪，該錯誤已經被報道！ http://code.opencv.org/issues/3179

，並已得到了解決： https://github.com/Itseez/opencv/pull/1244

還有 - 一個快速的解決方案：

開拓

[...]的OpenCV -2.4.6.1/modules/ts/include/opencv2/ts/ts_perf.hpp

圍繞線480編輯：

與以下內容：

#if defined(_MSC_VER) && (_MSC_VER <= 1400) 
#define CV_PERF_TEST_MAIN_INTERNALS_ARGS(...) \ 
    while (++argc >= (--argc,-1)) {__VA_ARGS__; break;} /*this ugly construction is needed for VS 2005*/ 
#else 
#define CV_PERF_TEST_MAIN_INTERNALS_ARGS(...) \ 
    __VA_ARGS__; 
#endif 
#define CV_PERF_TEST_MAIN_INTERNALS(modulename, impls, ...) \ 
    CV_PERF_TEST_MAIN_INTERNALS_ARGS(__VA_ARGS__) \'

代替：

#define CV_PERF_TEST_MAIN_INTERNALS(modulename, impls, ...) \ 
    while (++argc >= (--argc,-1)) {__VA_ARGS__; break;} /*this ugly construction is needed for VS 2005*/\

它或多或少這種變化對混帳：

爲我工作:-)
