mexmaci64 and dylib issue

Hi,

Thank you always for your help.

I have the following message in using a mexmaci64 file.

--------------------------------------------------------------------------------------------------------------------------------------

Library not loaded: @loader_path/libmex.dylib

Referenced from:

/Users/usr/Documents/MATLAB/SFMedu2/denseMatch/priority_queue_1.0/pq_create.mexmaci64

Reason: image not found.

--------------------------------------------------------------------------------------------------------------------------------------

I cannot see how should I solve this issue.

Thank you in advance.

Help,

I have this problem on a MacBook Pro running with Sierra.

error when running a mex file

@loader_path/libmex.dylib

Reason: image not found

In Walter proposal the depositery usr/lib is protected by Sierra

Thank you for a solution !

You would need to sudo in order to copy the file into /usr/lib

As your executable is not in /Applications you might be able to use setenv to set LD_LIBRARY_PATH. However if this is being run from MATLAB then that environment variable might not work in Sierra and later and you might need to put a copy of libmex into /usr/lib

Thank you very much, Walter Roberson.

I will try it as you suggested :)

Thank you Walter Roberson,

I tried to copy libmex.dylib and the other files as the error message suggested, but I finally cannot find "libSystem.B.dylib" and gave up to run on macOS. I will try it on Linux again.

Thank you very much for your help!

/usr/lib/libSystem.B.dylib should exist on any MacOS

I'm having the samen problem as @metro. Tried copying several files that error suggested, in total 4 files:

libmwlapack.dylib

libmwblas.dylib

libmex.dylib

libmat.dylib

when running I get the following error, this is slightly different from before:

Invalid MEX-file '/Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64': dlopen(/Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64, 6): Symbol not found: _mxAddField Referenced from: /Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64 Expected in: /usr/lib/libSystem.B.dylib in /Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64 Error in 'TDS_3dof_alloc/Allocation, and Tset to nset/Allocate qaudprog' (line 11) [x, err, lm]=qpip(Pmat, qmat, Gmat, hmat, Amat, btmp, [],[],[],[],[]);

For reference firste error:

Invalid MEX-file '/Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64': dlopen(/Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64, 6): Library not loaded: @loader_path/libmat.dylib Referenced from: /Users/quast/Documents/MATLAB/DP footprint local macAQ/3DOF/qpip.mexmaci64 Reason: image not found Error in 'TDS_3dof_alloc/Allocation, and Tset to nset/Allocate qaudprog' (line 11) [x, err, lm]=qpip(Pmat, qmat, Gmat, hmat, Amat, btmp, [],[],[],[],[]);

When looking for file libSystem.B.dylib I can't find it. Anybody know what is going on and how to solve it?
