8 years ago @hughhugh If you are using old version of OpenCV, use the corresponding release. mexopencv for v2.4 is here. Or, v2.3 is available via branch (git checkout v2.3 before build).

8 years ago @kyamagu I use opencv2.4.13, and in the directory of mexopencv, I use "git checkout v2.4" , and make command works. However , theres are still some errors when using 'make test'. What is the solution to the problem? Thank you .
The log as follows:

8 years ago @hughhugh see #212 or #123
Basically there are conflicting libraries (http://kyamagu.github.io/mexopencv/#linux), especially if you also have the "Computer Vision System Toolbox" from MathWorks (which also includes it's own opencv 2.4 libs).

Now in order to find conflicting libraries, you must run ldd both in the MATLAB command prompt and in the system shell, and look for differences in loaded libraries.
You didn't really need to uninstall CVST toolbox (that would be a last resort). You could have either temporarily moved the libopencv_*.so.2.4 libs inside the MATLAB bin directory, replace symlinks, or used the LD_PRELOAD preloading trick explained in the previous links I posted...
Alternatively you could switch to the latest OpenCV 3.1.0, avoiding conflict with MATLAB's included OpenCV 2.4.x. That way you can keep using both mexopencv and CVST at the same time (although there still might be conflicts in other indirect dependencies, just use ldd to sort it out)

8 years ago Did you clean the previous build artifacts? i.e., make clean
if that doesn't solve the issue, checkout the old tag.
Hi, I met this problem when make . What can I do to solve this issue? Thank you.
