dyld: Library not loaded in automatically generated shell script.

My problem is the "dyld: Library not loaded:" error that has been discussed several times in this forum. However the proposed solutions do not work for me. I wonder if its because MacOS has changed. The shell file seems to get the path right, and the file libmwlaunchermain.dylib is present in the target folder (/Applications/MATLAB/MATLAB_Runtime/v98/bin/maci64). So this does not seem to be the previously disccused error of not getting the path to the MCR correct. I also tried without the MCR, just using the installed Matlab (export MCR_ROOT=/Applications/MATLAB_R2020a.app) but this gave the same result.

In terminal, I run ./run_MainCalib.sh $MCR_ROOT SolverInputs.mat

This generates

MCRROOT is /Applications/MATLAB/MATLAB_Runtime/v98

DYLD_LIBRARY_PATH is ./Applications/MATLAB/MATLAB_Runtime/v98/runtime/maci64:/Applications/MATLAB/MATLAB_Runtime/v98/bin/maci64:/Applications/MATLAB/MATLAB_Runtime/v98/sys/os/maci64

I read https://www.mathworks.com/matlabcentral/answers/473971-how-do-i-configure-the-ld_library_path-on-linux-and-dyld_library_path-on-mac-os-x-to-point-to-mcr, which seems to suggest the problem is that MacOS has changed the way environment variables propagate within nested shells, but the solution proposed there does not apply directly to running a standalone from a shell file, as the shell script creates the DYLD_LIBRARY_PATH and the shell script is automatically generated by matlab.

any response/support from MathWorks?

I have an almost identical problem. MathWorks?

If I recall correctly, the solution was to give up trying to compile in Terminal and instead use the compile facilities from within the Matlab prompt. I have been away from this project for a few years, so I cannot remember the details. Here is the code from the .m file I wrote around that time to compile from within Matlab,

%MacMexFile.m

%creates SS_Solve

%define macro variables;

startdir = pwd; %remember where we were

HomeDir = getenv('HOME') ;

CompVar = computer;

if strcmp(CompVar,'MACI64'), %mac

NRfolder = [HomeDir '/Dropbox/Libraries/clibs/NumRec/NR3Code']; %I prefer not to create extra copies of the NR code

ProgDir = [HomeDir '/Dropbox/Papers/EducMatch']; %where the code is stashed

else %linux

ProgDir = [HomeDir '/EducMatch']; %where the code is stashed

NRfolder = ProgDir; %where the numerical recipe .h files are stored

end

CPPDir = [ProgDir '/CPPCode'];

CPPstr = 'SS_Solve.cpp EquilObjects.cpp Erf_JK.cpp StaticConditions.cpp SteadyStateStruct.cpp';

Product = [ProgDir '/Matlab/SolveMatch/SS_Solve'];

cmdstr=['mex ' CPPstr ' -I' CPPDir ' -I' ProgDir ' -I' NRfolder ' -output ' Product];

addpath(genpath('ProgDir')) %put all the .m files on the path;

eval(['cd ' CPPDir]) %so that matlab knows where these files are

eval(cmdstr) %main event: compile the mex file

eval(['cd ' startdir]) %return us to initial folder

Thank you for your response. However, I am in fact using Matlab Compiler.
