Greetings,
I'm having trouble compiling a simple test application using Eigen with the MKL backend:

test.cpp:

Code: Select all

#define EIGEN_USE_MKL_ALL
#include "Eigen/Dense"
int main()
{
    return 0;
}


Running OS X 10.7 with MKL included in the latest Intel Parallel Composer XE (MKL 10.3 Update 11) and Eigen 3.1.1. I've tried various compilers, each yields different errors:

They all seem to be complaining about more or less the same thing but I have no idea what I'm doing wrong.

should be fixed in the repo.

Confirmed, thanks!

However, now receiving the following error at runtime:

Code: Select all

MKL ERROR: Parameter 13 was incorrect on entry to SGEMM

I cannot reproduce. Could you paste the backtrace, thanks.
