Hi Developers, Users,
I am trying to use a "typedef" to wrap EigenSystem into TransientSystem:
*typedef TransientSystem<EigenSystem> TransientEigenSystem;*
I will eventually use this in MOOSE. I went to
examples/eigenproblems/eigenproblems_ex1 to add one line to test this:
*TransientEigenSystem & trst_eigen_system3 =
equation_systems.add_system<TransientEigenSystem>
("Transient_Eigen_System");*
There is a link error:
*CXX example_opt-eigenproblems_ex1.o CXXLD example-optUndefined
symbols for architecture x86_64:
"libMesh::TransientSystem<libMesh::EigenSystem>::TransientSystem(libMesh::EquationSystems&,
std::__1::basic_string<char, std::__1::char_traits<char>,
std::__1::allocator<char> > const&, unsigned int)", referenced from:
libMesh::TransientSystem<libMesh::EigenSystem>&
libMesh::EquationSystems::add_system<libMesh::TransientSystem<libMesh::EigenSystem>
>(std::__1::basic_string<char, std::__1::char_traits<char>,
std::__1::allocator<char> > const&) in example_opt-eigenproblems_ex1.old:
symbol(s) not found for architecture x86_64clang-3.7: error: linker command
