This error will occur if the provided libraries or the Network License Manager binaries are not present in their default location. When you download just the Network License Manager binaries and libraries from https://www.mathworks.com/support/install/license_manager_files.html they are packaged in a particular way that allows them to utilize each other. If these directories are moved around then the Network License Manager binaries will not be able to automatically locate the necessary libraries.
To resolve this issue, please create the following environment variable: LD_LIBRARY_PATH
This environment variable will contain the location of the libraries that the MATLAB vendor daemon is required to use. After doing so, you can start the Network License Manager in reference to that environment variable:
setenv LD_LIBRARY_PATH {path_to_libraries};{flex path}/lmgrd -c license.dat -l logfile
Example:
setenv LD_LIBRARY_PATH /Libraries/MathWorks;/usr/local/MATLAB/R2014a/etc/glnxa64/lmgrd -c ./license.dat -l ./logfile.txt
You will have to use the above command to start license manager every time.
