Mex files are not produced upon building (Youtube Video Instructions)

[SamMans]

Hi, in my case only the ezc3d.dll file was generated in the install directory. The mex files were not produced. I followed the same exact steps tho. I copied the resulting .dll file into the MATLAB directory and tried to test the ez3cd read command, but it didn't recognize the command which means the compiling failed.

Dear @SamMans ! Can you provide a screen shot of the CMake and a screenshot/copy-paste of the compiling output? Thanks :)

Cmake screenshots (by Cmake, I believe you mean the Cmake gui hopefully): All_Build build step output:

Can you please change the Matlab_ezc3d_INSTALL_DIR for a folder on which you have written access (or run Visual Studio with adminstrative rights), and send me the output again

[SamMans]

This is the latest Install build (I repeated the whole process after deleting the old files and the previous failure seems to have been mitigated, but still no mex files, just .dll):

C:/Program Files/MATLAB/R2022a/toolbox/ezc3d_matlab/ezc3dRead.mexw64

The mex is at that location

[pariterre]

That said, your CMAKE_INSTALL_PREFIX is wrong (C:\Users\Samer\Documents\ezc3d\install), the "\" should read either "\" or "/" (this is a well-known windows problem)

[SamMans]

Yes, I was about to edit my previous comment (I haven't read the output properly, sorry about that). Should I copy the mex files along with the .dll produced in a user-defined ezc3d directory (In the Youtube video, it was Documents/MATLAB/ezc3d), or should I use them in the directory they were installed at right away and save my breath?

[pariterre]

Since you installed the library in the "toolbox" folder, you can simply use it as is (assuming you've added C:/Program Files/MATLAB/R2022a/toolbox/ezc3d_matlab/ in your search path in matlab)

Enjoy :)

[SamMans]

Oh yeah. I tried that and it worked. Thank you very much for your help!!
