linear solver option if Ipopt compiled without linear solver
|Reported by:||stefan||Owned by:||ipopt-team|
if I compile Ipopt/trunk without any linear solver available, then the linear_solver option does not work correct. Here is what print_options_documentation gives me:
linear_solver ("ma27") Linear solver used for step computations. Possible values: - use the Harwell routine MA27 [ma57] - use the Harwell routine MA57 [pardiso] - use the Pardiso package [wsmp] - use WSMP package [taucs] - use TAUCS package (not yet working) [mumps] - use MUMPS package [custom] - use custom linear solver [Determines which linear algebra package is to be used for the solution of the augmented linear system (for obtaining the search directions). Note, the code must have been compiled with the linear solver you want to choose. Depending on your Ipopt installation, not all options are available.]
Please, please, please, have a look at IpAlgBuilder.cpp:120 and, e.g., add some #else branch for the #ifdef COIN_HAS_MUMPS.
