Package: coinor-libipopt0
Version: 3.8.3-1
Severity: important
Hi,
the Ipopt package uses "ma27" as a default solver. Setting option
"print_options_documentation" reveals this:
---cut---
### Linear Solver ###
linear_solver ("ma27")
Linear solver used for step computations.
[...]
---cut---
The default solver should be MUMPS.
Setting option "linear_solver" to "mumps" fails:
---cut---
Exception of type: OPTION_INVALID in file "IpAlgBuilder.cpp" at line 381:
Exception message: Selected linear solver MUMPS not available.
---cut---
Looking into IpAlgBuilder.cpp reveals that MUMPS is disabled by macro
COIN_HAS_MUMPS (probably because it wasn't available at "configure"-time):
---cut---
else if (linear_solver=="mumps") {
#ifdef COIN_HAS_MUMPS
SolverInterface = new MumpsSolverInterface();
#else
THROW_EXCEPTION(OPTION_INVALID,
"Selected linear solver MUMPS not available.");
#endif
}
---cut---
Many thanks for packaging Ipopt for Debian! :-)
Cheers, Michael
