Follow-up Comment #1, bug #37031 (project octave):
I have a test program (below) that looks to do the job.
#include "umfpack.h"
int
main ()
{
double stats [2];
umfpack_tic (stats);
umfpack_toc (stats);
return 0;
}
If built without the SuiteSparse lib I get;
$ gcc -o conftest conftest.cc -I/opt/local/include -L/opt/local/lib
-lumfpack
Undefined symbols for architecture x86_64:
"_SuiteSparse_time", referenced from:
_umfpack_tic in libumfpack.a(umfpack_gn_tictoc.o)
_umfpack_toc in libumfpack.a(umfpack_gn_tictoc.o)
ld: symbol(s) not found for architecture x86_64
If built with the SuiteSparse library there is no error.
$gcc -o conftest conftest.cc -I/opt/local/include -L/opt/local/lib -lumfpack
-lSuiteSparse
Looks like this will be easy to use to create a changeset to allow Octave to
link against SuiteSparse 4.0.x. I have a busy schedule and may not get to
this quickly. If anyone is in a hurry, please feel free to take this on.
