<p>Ok, thanks for the information. Let's try something simple... can you compile the following program and execute it?</p>
<pre><code>#include <armadillo>
using namespace arma;
int main()
{
mat x = randu<mat>(50, 50);
vec e = eig_sym(x);
cout << "Eigenvalues:\n" << e.t();
}
</code></pre>
<p>You might have to fix silly problems since I didn't actually compile and test that. But you should be able to compile with <code>g++ -std=c++11 test.cpp -larmadillo</code>. If that compiles and you run it, do you again encounter a SIGILL?</p>
