Hi all,

I've been using Eigen + SuperLU3.0 for some time but now I need to upgrade to SuperLU4.0 to avoid multithreading problems in old SuperLU versions.

When linking my code against SuperLU3.0 everything works fine, but when I link against SuperLU4.0 and execute any test, I'm always getting this error message:

** On entry to dgssvx, parameter number 13 had an illegal value

Have anyone seen this kind of error before?

Thanks!

SuperLU 4.0 works fine for me using the development branch of Eigen. What test fails?

First of all, thanks for answering so fast.

My code is:

Code: Select all

[...]

SparseMatrix<double >*  m = new SparseMatrix<double >(n,n);
VectorXd b(n);
VectorXd x(n);

// Fill matrix m and vector b.

SparseLU<SparseMatrix<double>, SuperLU > * sparseLU = new SparseLU<SparseMatrix<double>, SuperLU >(*m);
sparseLU->solve(b, &x);
[...]


And I get the error message in SparseLU<MatrixType,SuperLU>::compute(const MatrixType& a) method, when SuperLU_gssvx(...) method is called.

P.S: I ran this test using Eigen 2.0.11. I'll try with development branch.

yes, support for SuperLU 4 has been done in the devel branch only.

Ok, now it works! The problem was the version of Eigen I picked.

Thanks a lot for your help!
