Hi, I have difficulties compiling and using mexopencv. I seek inform

Problems compiling and using mexopencv,about kyamagu/mexopencv

Hmm, the compilation error seems to be due to the API change in cv::Param struct in OpenCV v2.4.x. It compiles in version 2.4.3, whereas it doesn't compile in the latest beta or in earlier v2.4.x. I'd remove erroneous cv::Param mapping in this file.

It doesn't look like the runtime error is related to this, though. Can you check the output of ldd tool from inside and outside of matlab? That is,

In shell:

$ ldd +cv/anyfunction.mexa64

In Matlab:

>> !ldd +cv/anyfunction.mexa64

from mexopencv.

Inserted below are output from 'ldd'. Can you tell me what you are looking for? I see, that there are some 'not found'. I'll try and fix those.

I'll try to install OpenCV v.2.4.3 in a moment and give it a try.

Thank you

I wanted to see if there is a different shared object between what the system sees and what is actually loaded. It seems that probably you need to preload libgcc_s.so in addition to libstdc++.so. There might be others.

As for the opencv version, please pull the latest mexopencv commit. The issue should be gone now.

Pulled lastest mexopencv and now everything compiles fine. Great.

Installed OpenCV 2.4.3.

Working through preloading, but MATLAB is still crashing. Is there a strategy for picking which to preload?

Suspicious shared objects in your case are prefixed with matlab path: /usr/local/MATLAB/R2012b/sys/os/glnxa64/ . Maybe you can use grep to filter out the ldd output. Other than that, you might want to use gdb to see what is giving a crash. You can start matlab with -Dgdb option:

$ LD_PRELOAD=/usr/lib64/libstdc++.so.6:/lib64/libgcc_s.so.1 matlab -Dgdb
(gdb) run -nodisplay
>> im = cv.imread('test/cat.jpg');
…
(gdb) bt

I have a long list of preloads, and it is working now. I will clean up the preloads and test later. I'll post my findings.

Shamelessly long preload:

LD_PRELOAD='/lib64/libgcc_s.so.1 /usr/lib64/libtiff.so.5 /usr/lib64/libQtOpenGL.so.4 /usr/lib64/libQtGui.so.4 /usr/lib64/libQtCore.so.4 /usr/lib64/libfreetype.so.6 /usr/lib64/libstdc++.so.6' matlab

Thank you very much for your help on both preloads and fixing the source. I think it is a really useful toolbox for my image analysis prototyping. Thank you for that addition.

Just a note, maybe you can alias matlab in your shell. Good luck!

axjensen commented on July 18, 2024

Yes, aliasing is a good idea. I'm using an application launcher instead. The following works fine for me:

LD_PRELOAD='/lib64/libgcc_s.so.1 /usr/lib64/libQtOpenGL.so.4 /usr/lib64/libQtGui.so.4 /usr/lib64/libQtCore.so.4 /usr/lib64/libstdc++.so.6' matlab
