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

Hello,
I use the current version of numeric bindings to use ublas with umfpack. I tried the example umfpack_simple from the test folder:
..
umf::symbolic (A, Symbolic);
  umf::numeric (A, Symbolic, Numeric);
  umf::solve (A, X, B, Numeric);
…
But I got the error:
error: no matching function for call to 'symbolic(sparsematrix_t&, boost::numeric::bindings::umfpack::symbolic_type<double>&)'
it seems there is no function symbolic,numeric and solve. There is one in the namespace detail with different arguments.
Can someone help me please with this example.
Thank you in advance
Niklas
