            Bug ID: 260613
           Summary: graphics/opencv
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: tcberner@freebsd.org

Any use of the opencv C++ library leads to a segfault (as for python3 too):

version.cpp:
#include <opencv2/opencv.hpp>
int main() {
    std::cout << "The current OpenCV version is " << CV_VERSION << "\n";
    return 0;
}

$ g++ -ggdb -o version `pkg-config --cflags --libs opencv4` version.cpp
$ ./version
Segmentation fault (core dumped)

gdb bt shows:
#0  0x00000008119ca938 in vtable for __cxxabiv1::__si_class_type_info () at
/lib/libcxxrt.so.1

I tried to build the port using WITH_DEBUG, but in this case, one cannot
compile anymore:
$ g++ -ggdb -o version `pkg-config --cflags --libs opencv4` version.cpp 
/usr/local/bin/ld: /usr/local/lib/libopencv_sfm.so: undefined reference to
`google::base::CheckOpMessageBuilder::NewString[abi:cxx11]()'
collect2: error: ld returned 1 exit status

Using:
- FreeBSD-13.0-p5
- g++ (FreeBSD Ports Collection) 10.3.0
- opencv: 4.5.3_4

Any clue on this ? Thanks,
