Matlab Runtime correct version installed on Linux environment but getting error message could not find the correct version.

I had installed Matlab Runtime environment version v911 and can see folders and libraries inside the default installation path on a linux pc ("/usr/local/MATLAB/MATLAB_Runtime"), Also added library_path correctly , when tried to run one code which uses the compiled libraries i am seeing an error like this any help

Error: Could not find version 9.11 of the MATLAB Runtime.

Attempting to load libmwmclmcrrt.so.9.11.

Please install the correct version of the MATLAB Runtime.

Contact your vendor if you do not have an installer for the MATLAB Runtime

Hi @nikhil koyyodan,

The issue may stem from an incorrect configuration of the LD_LIBRARY_PATH environment variable when executing the binary. This variable defines the directories where the system looks for runtime libraries.

Further information can be found in the following MATLAB Answer:

https://www.mathworks.com/matlabcentral/answers/1806740-why-do-i-receive-error-while-loading-shared-libraries-libmwmclmcrrt-so-x-x-when-i-run-my-compiled

It is possible that incompatible or unintended library versions are listed earlier in the LD_LIBRARY_PATH than the version required by the binary. Placing the correct library paths at the beginning of the variable may help ensure that the appropriate versions are used.

I hope this helps resolve the issue and enables the binary to run as expected.

hi , i am still facing same error message ,LD_LIBRARY path i added i checked any unintended version is there by checking $LD_LIBRARY_PATH but it was blank, later i added the path using export LD_LIBRARY_PATH=/usr/local/MATLAB/Matlab_Runtime/v911/runtime/glnxa64: /usr/local/MATLAB/Matlab_Runtime/v911/bin/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/sys/os/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/sys/opengl/lib/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/extern/bin/glnxa64:$LD_LIBRARY_PATH then i tried to run the code but getting error like ("error while loading shared libraries:libmwlaunchermain.so cannot find shared object file no such files or directory , i understood its a path issue and added the lib path in /etc/ld.so.conf file and then its atleast taking libraries it seems but getting another error like this Error: Could not find version 9.11 of the MATLAB Runtime.

Attempting to load libmwmclmcrrt.so.9.11.

Please install the correct version of the MATLAB Runtime.

which i mentioned above.

Hi @nikhil koyyodan,

Since LD_LIBRARY_PATH is not set, the export statement would resolve to only the new path you specified, resulting in a trailing colon at the end. This trailing colon may be causing the issue.

In your case, the path resolves to:

/usr/local/MATLAB/Matlab_Runtime/v911/runtime/glnxa64: /usr/local/MATLAB/Matlab_Runtime/v911/bin/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/sys/os/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/sys/opengl/lib/glnxa64:/usr/local/MATLAB/Matlab_Runtime/v911/extern/bin/glnxa64:

Please note the trailing colon at the end of the path. This can lead to unexpected behavior. Kindly remove the $LD_LIBRARY_PATH reference along with the trailing colon from your export statement, and then try running the binary again.

Additionally, I noticed a space after the first colon in your original path. If this was not intentional, please ensure that there are no spaces between the path components separated by colons.

Following is the official MathWorks Documentation to setup MCR to run with applications:

[nikhil koyyodan]

i had removed the end colon and $LD_LIBRARY_PATH but still seeing the same error, now when i do echo $LD_LIBRARY_PATH i am getting like this

/tool# echo $LD_LIBRARY_PATH

/usr/local/MATLAB/MATLAB_Runtime/v911/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/sys/opengl/lib/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/extern/bin/glnxa64

error message

Error: Could not find version 9.11 of the MATLAB Runtime.

Please install the correct version of the MATLAB Runtime.

Contact your vendor if you do not have an installer for the MATLAB Runtime.

Also i want to export LD_PRELOAD i added like this is this fine

export LD_PRELOAD=/usr/local/MATLAB/MATLAB_Runtime/v911/bin/glnxa64/glibc-2.17_shim.so

[Swastik Sarkar]

Could you please share the compiled application by attaching it here? This would help us reproduce the issue and assist more effectively.

[nikhil koyyodan]

ok, pls try to run by giving sudo ./file and see if you are also getting the error in linux system.

[Swastik Sarkar]

If you are using sudo, please try changing the command to the following and let us know of the results:

sudo -E ./file

The argument -E preserves environment variables while executing the program

[nikhil koyyodan]

Hi @Swastik Sarkar tried running with sudo -E ./file , still seeing the same error

/tool# echo $LD_LIBRARY_PATH

/usr/local/MATLAB/MATLAB_Runtime/v911/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/sys/opengl/lib/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v911/extern/bin/glnxa64

/tool# sudo -E ./file

Error: Could not find version 9.11 of the MATLAB Runtime.

Attempting to load libmwmclmcrrt.so.9.11.

Please install the correct version of the MATLAB Runtime.

if i try without sudo append eg (./file) its checking some libfiles in my present working directory and giving another error message,as no lib files are in my PWD.

libmat.so: cannot open shared object file: No such file or directory

Error: mclmcr initialization failed

[nikhil koyyodan]

Hi @Swastik Sarkar ,is this path issue when trying to load libmwmclmcrrt.so.9.11 its seeing this issue right..also when i tried command line (ldd ./file) it showed the paths correctly from my PWD

Hi @Swastik Sarkar, i am able to run now some path related issue only. thanks

[Swastik Sarkar]

Hi @nikhil koyyodan,

That's awesome !

If you can, please do let us know what different you have done apart from the above steps.
