Hi,

I'm using:

#include <Eigen/Sparse>
#include <unsupported/Eigen/UmfPackSupport>

If I use the compile flag -std=c++0x I get multiple errors like:

eigen/unsupported/Eigen/src/SparseExtra/UmfPackSupport.h: In function ‘int Eigen::umfpack_symbolic(int, int, const int*, const int*, const std::complex<double>*, void**, const double*, double*)’:
/eigen/unsupported/Eigen/src/SparseExtra/UmfPackSupport.h:55: error: lvalue required as unary ‘&’ operand

I'm using g++ (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5, libumfpack5.4.0, eigen-3.0-beta2

I've got no clue on how to solve this. Can anyone help me fix this problem?

Cheers,
traubi

Hi,

I switched to Super LU which solves my problem for now.

I added parenthesis around Ax[0].real(), this should fix the issue.

Thanks, I will try it as soon as possible.
