Description
I installed using macport gcc48 and opencv. I tried to compile a simple opencv example with the compiler and I get:
Undefined symbols for architecture x86_64:
"cv::namedWindow(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)", referenced from:
_main in ccot2eJS.o
"cv::VideoCapture::VideoCapture(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)", referenced from:
_main in ccot2eJS.o
"cv::imshow(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, cv::_InputArray const&)", referenced from:
_main in ccot2eJS.o
ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status
If i use the gcc provided by apple or clang the program compiles. I also tried to recompile opencv by myself and i still get the same error. I tested all this also on a second machine having the same results. It seems that there is some incompatibility between gcc48 and opencv.
