Linking issue with Matlab Coder....

Hi, I am trying to link to some existing precompiled libraries using Matlab Coder. Within my code I have the following.....
libPriority = '';
libPreCompiled = true;
libLinkOnly = true;
linkPath = '/home/arwel/Documents/coding/multinestEdits/eggboxOnly/MultiNest_v3.10_eggboxOnly/multinest_eggboxOnly/lib';
coder.updateBuildInfo('addLinkObjects','libmultinest.so',linkPath,libPriority,libPreCompiled,libLinkOnly);
coder.updateBuildInfo('addLinkObjects','libmultinest.so.3.10',linkPath,libPriority,libPreCompiled,libLinkOnly);
coder.ceval('mainRoutine',0,[]);
When i try to make the mex in Coder, it fails during the testing of the generated mex. However it will still make the mex.
If I try to run it I get the following error message...
>> multinestCaller_mex() Invalid MEX-file '<.......>/multinestTests/multinestCaller_mex.mexa64': libmultinest.so.3.10: cannot open shared object file: No such file or directory.
I have verified that both 'libmultinest.so' and 'libmultinest.so.3.10' are in the same directory. Why is it that it seems to find one library and not the other, given that they are both in the same place?

You may try using ldd on the mex file to figure out what .so file libmultinest.so is being resolved to. Once you verify that, you can try to put libmultinest.so.3.10 in the same path or put a symlink to libmultinest.so.3.10.

Hi Arwel,
Can you check whether '/home/arwel/Documents/coding/multinestEdits/eggboxOnly/MultiNest_v3.10_eggboxOnly/multinest_eggboxOnly/lib' is on your LD_LIBRARY_PATH?
