我在OS X 10.10.3 Yosemite上遇到g ++編譯器錯誤(編譯OpenCV 3.0 beta)。無法識別的命令行選項'-stdlib = libstdC++'
g++ -v
Using built-in specs.

改爲使用Clang:'export CC = clang'。 – jww
$ CC = clang CXX = clang ++ cmake -DCMAKE_INSTALL_PREFIX =/usr/local -Wno-dev -DNVCC_FLAGS_EXTRA =「 - Xcompiler -stdlib = libstdC++; -Xlinker -stdlib = libstdC++」-DOPENCV_EXTRA_CXX_FLAGS =「 - stdlib = libstdC++」-DOPENCV_EXTRA_EXE_LINKER_FLAGS = 「-stdlib = libstdC++」.. – dbl001
仍然不正確... - C/C++: - 構建爲動態庫?:是 - C++編譯器:/ opt/local/bin/C++(ver 4.8.4 ) - C++ flags(Release):-stdlib = libstdC++ -O3 -DNDEBUG -DNDEBUG - C++ flags(Debug):-stdlib = libstdC++ -g -O0 -DDEBUG -D_DEBUG - C編譯器:/ opt /本地/ bin/gcc - C標誌(發佈):-fsigned-char -W -Wall -Werror =返回類型 - – dbl001
