building opencv 2.4.6 on Mac - Mavericks - c++

Question

I downloaded opencv 2.4.6 for mac OSX (Mavericks). Untared the tar file and made the following steps:
cd opencv-2.4.6.1/
mkdir build
cd build/
cmake -G "Unix Makefiles" ..
make -j8
But I get an error on the build

Answer 1

I used this compilation options for cmake:
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 ..

Answer 2

It's strange, the bug hase already been reported! http://code.opencv.org/issues/3179
And have already been solved:
https://github.com/Itseez/opencv/pull/1244
Still - for a quick solution:
Open up the
[...]opencv-2.4.6.1/modules/ts/include/opencv2/ts/ts_perf.hpp
Edit around line 480:
with the following:
#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__) \'
instead of:
#define CV_PERF_TEST_MAIN_INTERNALS(modulename, impls, ...) \
while (++argc >= (--argc,-1)) {__VA_ARGS__; break;} /*this ugly construction is needed for VS 2005*/\
Its more or less this change on git:
https://github.com/vkocheganov/opencv/commit/e4b201be25ff92e930b979098e94a89368677313
Worked for me :-)
