MATLAB: Am I not able to open the SimMechanics library on the 64-bit Linux machine in MATLAB 7.6 (R2008a)

Simscape Multibody

I receive the following error messages when I try to open my SimMechanics model with a 32-bit version of MATLAB on a 64-bit Linux machine:
 Warning: Error evaluating 'LoadFcn' callback of Spherical block (mask)
 'mblibv1/Joints/Spherical'. Unable to load 'mechanical' due to the following

Best Answer

As the error messages suggest, the SimMechanics shared libraries were not loaded correctly, which caused an issue with the symbols defined in these libraries. Using 32-bit SimMechanics libraries on a 64-bit machine is not supported. Ensure that you are using a 64-bit installation of MATLAB to use SimMechanics on a 64-bit machine.
