在 Mac 上构建 opencv 2.4.6 - Mavericks
building opencv 2.4.6 on Mac - Mavericks
我下载了适用于mac OSX（Mavericks）的opencv 2.4.6。解压缩 tar 文件并执行以下步骤：
cd opencv-2.4.6.1/
mkdir build
cd build/
cmake -G "Unix Makefiles" ..
make -j8
但是我在构建时遇到错误

我为cmake使用了这个编译选项：
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 ..
奇怪的是，已经报告了该错误！ http://code.opencv.org/issues/3179
并且已经解决了：https://github.com/Itseez/opencv/pull/1244
<小时 />仍然 - 对于快速解决方案：
- 打开
[...]opencv-2.4.6.1/modules/ts/include/opencv2/ts/ts_perf.hpp
- 在第 480 行周围编辑：
与以下内容：
#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__) '
而不是：
#define CV_PERF_TEST_MAIN_INTERNALS(modulename, impls, ...)
while (++argc >= (--argc,-1)) {__VA_ARGS__; break;} /*this ugly construction is needed for VS 2005*/
- 它或多或少在 git 上发生了这种变化：
https://github.com/vkocheganov/opencv/commit/e4b201be25ff92e930b979098e94a89368677313
