Hello all,
I'm trying to run a build Simulink file that uses the UDP receive block. I know that this block requires additional .dll library files (.so since I'm using Ubuntu) so I use the PackNGo function to create a zip. I place the extracted zip on another pc (using ssh commands) and try to run the executable as super user. The following error occurs:
"could not open library: libmwnetworkdevice.so"
Notice that the PC on which I try to run the executable does not have a MATLAB installation. I want to run the file without it.
The permissions for this file seems correct, I tried to copy the file to the folder where the executable is located but this does not change anything.
When I try to run the same file without the UDP Receive block it works properly. What could cause this and is there a solution to this problem?
thanks in advance

Hi Joris,
Please first ensure that the file "libmwnetworkdevice.so" is on your computer. You should be able to find a copy of the file within your MATLAB root directory (e.g., <matlabroot>/bin/glnx86). The path of the MATLAB root directory can be obtained by typing
>> matlabroot
in the MATLAB Command Window. Once you have located the file, ensure that the path of this file is included as part of the LD_LIBRARY_PATH system environment variable. You should now be able to run the executable file.

Jeremy,
Did you locate the "libmwnetworkdevice.so" in the folder location <matlabroot>/bin/glnx64? If so, I cannot seem to find it in this location. I am tackling the exact same issue with cross compilation and really do need to obtain the .so file.
