Re: [Libmesh-users] compilation for complex numbers

Yes, so this is embarrassing: Prior to my first post I configured libmesh _and_ petsc for complex but did not use --with-clanguage=cxx. When recompiling I forgot --enable-complex for libmesh, so you are right. So the conclusion was that --with-clanguage=cxx for petsc did the trick. Why do I ne

Are you sure you've compiled PETSc in complex mode? On Fri, Aug 16, 2013 at 8:54 AM, Jens Lohne Eftang wrote: > I'm using gcc 4.7 > > I tried --with-clanguage=cxx for PETSc, but that did not resolve > everything. > > Now I get another error message during libmesh compilation: > > > CXX src/

Re: [Libmesh-users] compilation for complex numbers

I'm using gcc 4.7 I tried --with-clanguage=cxx for PETSc, but that did not resolve everything. Now I get another error message during libmesh compilation: CXX src/numerics/libmesh_dbg_la-dense_matrix_blas_lapack.lo src/numerics/dense_matrix_blas_lapack.C: In instantiation of 'void libMes

Re: [Libmesh-users] compilation for complex numbers

I use " --with-clanguage=cxx" in the PETSc configuration. Can you try adding that? David On 08/16/2013 03:24 AM, Jens Lohne Eftang wrote: > I want to configure and compile libmesh for complex number support. > > However I get the following error when making libmesh: > > In file included from ./

[Libmesh-users] compilation for complex numbers

I want to configure and compile libmesh for complex number support. However I get the following error when making libmesh: In file included from ./include/libmesh/tensor_tools.h:25:0, from src/numerics/numeric_vector.C:33: ./include/libmesh/compare_types.h:65:37: error: template
