Error installing qpOASES_e MATLAB interface

[eliasp525]

Hi,

I am having trouble installing qpOASES_e for MATLAB. I am trying to do a benchmark of different QP solvers for MPC and I want them all to be implemented in C.

I get the following output after I run make in qpOASES-qpOASES_e\releases\3.1.2\interfaces\matlab:

>> make

Error in make (line 115)
            eval( cmd );

Any ideas on how to fix this?
I have already installed the standard C++ interface and it works fine.
