Unable to statically link `OpenCV` without `OpenCL` support on windows.
i have been experimenting with the crate, and found that if i disable OpenCL
when compiling the static lib files of OpenCV
, i am unable to link it correctly to my app.
I get the following link error:
libopencv-3b3b70e538e42495.rlib(8cdb024d75981777-core.o) : error LNK2019: unresolved external symbol "public: bool __cdecl cv::ocl::Kernel::run_(int,unsigned __int64 * const,unsigned __int64 * const,bool,class cv::ocl::Queue const &)" (?run_@Kernel@ocl@cv@@QEAA_NHQEA_K0_NAEBVQueue@23@@Z) referenced in function cv_ocl_Kernel_run__int_size_tX_size_tX_bool_const_QueueR

I am not sure why OpenCL
symbols are being generated in the first place, since i set the WITH_OPENCL
flag to OFF, when compiling OpenCV
? Any clues what might be happening here?
I am not sure, if the output of cargo b -vv
would be helpful here, but i am more than happy to provide it, if need be.
Do you still have this issue? If so cargo build -vv
is always useful to provide the insight into what's happening during binding generation. Please also be sure to use the latest crate version (0.90.0 at the moment of writing)
