Hi Daniel,
I was able to sort this issue out. What I did was removed everything
related to armadillo in the cmakelists.txt and just linked armadillo to my
target using the following line in the end of the file
TARGET_LINK_LIBRARIES(${TARGET} armadillo)
I am able to run small programs using armadillo within dealii.
I have another question which might not be in the scope of this forum.
However, since you and Jean have worked with armadillo (by looking at the
Ceres code gallery program), I was wondering if any of you can help.
My question is, I want to use the eigenvalue problem solving capability of
armadillo in my code. However, my matrix type is of BlockSparseMatrix in
dealii. How do I go about using my BlockSparseMatrix with the available
armadillo functions that use sp_mat type matrices
<http://arma.sourceforge.net/docs.html#SpMat>? One idea that I thought was
to print my block_sparse_matrix using the function block_write()
<https://www.dealii.org/current/doxygen/deal.II/classSparseMatrix.html#a8b32b99a054482f06fc026248c27bb74>
that prints the dealii Sparse_matrix in a binary format. However, I am not
able to read that file using armadillo's functionality to load binary files
<http://arma.sourceforge.net/docs.html#save_load_mat>.
Thanks!
