Hi,
the support for SuperLU is broken:
#define ARMA_USE_SUPERLU 1
#include <armadillo>
int main()
{
arma::sp_mat A = arma::sprandu<arma::sp_mat>(1000, 1000, 0.1);
arma::vec b = arma::randu<arma::vec>(1000);
arma::vec x = spsolve(A, b, "superlu");
return 0;
}
With "g++ arma.cpp -larmadillo" I get (abbreviated):
In file included from /usr/include/armadillo:114,
from arma.cpp:2:
/usr/include/armadillo_bits/include_superlu.hpp:232:84: note: ‘#pragma
message: WARNING: SuperLU headers not found; using built-in definitions’
232 | #pragma message ("WARNING: SuperLU headers not found; using
built-in definitions")

/usr/bin/ld: /tmp/ccAYEdY9.o: in function
`arma::superlu::init_stat(arma::superlu::SuperLUStat_t*)':

This is probably because Armadillo 14.2 requires SuperLU 5.2 (see
/usr/include/armadillo_bits/include_superlu.hpp:67). Actually, SuperLU 5.3 as
in bookwork seems to work, too. But trixie has SuperLU 7.0.1. Armadillo 14.6
supports SuperLU 7.x.
When this has been fixed it is probably a good idea to re-add a versioned
depends on libsuperlu-dev to bound it from above. Also an autopkgtest for this
feature would be useful.
Best regards,
Joachim
