Hi Thomas,
Sorry the sparsematrix_t is a definition from me:
typedef uBlas::compressed_matrix<double, uBlas::column_major, 0, uBlas::unbounded_array<int>, uBlas::unbounded_array<double> > sparsematrix_t;
It compiles now, I think the problem was that the include 
#include <Core/Utils/numeric/bindings/ublas.hpp>
was missing.
Best regards and thank you for your help
Niklas

This is strange. I cannot find "sparsematrix_t" anywhere, neither in the source code of the examples, nor in the source code of the bindings.

those functions can be found in bindings/umfpack/umfpack,hpp also in the umfpack namespace. Maybe some lookup rules prevent the compiler to consider them. 
Do you have any idea why the compiler talks about "sparsematrix_t"? Can you tell me the compiler you are using, including its version and maybe relevant compile flags (like -c++11 ...)? Maybe tell me also the version of boost, so that I can try to exactly reproduce this myself. 
The compiler and the boost version on the computer I used for testing are quite old, but at least they were able to compile and execute the test successfully. 
Regards, 
Thomas
