hi, when I compile the mexopencv v3.0.0 with opencv_contrib, there is the issue as below:

 /tmp/mex_111712642399060_26970/LSVMDetector_.o: In function `mexFunction':

check if there is a "LSVMDetector()" in your src code?

chenfsjz commented 5 years ago

@Dzhange there is a "LSVMDetector_.cpp" in the folder ,

mexopencv/opencv_contrib/src/+cv/private

and if I delete this file, the rest modules in opencv_contrib can be compiled successfully

make sure you are using matching versions, v3.0.0, of opencv, opencv_contrib, and mexopencv

If you are still having problem, please include more info (OS, matlab, how you build/install opencv, build commands and options, versions, etc.)

Also refer to the wiki which contains detailed build instructions.
