cvanaret / Uno

A next-gen solver for nonconvex optimization. Uno is a Lagrange-Newton solver that unifies barrier and SQP methods in a modern and generic way, and implements different globalization flavors (line search/trust region and merit function/filter method/funnel method). Competitive against filterSQP, IPOPT, SNOPT, MINOS and CONOPT.

Building without BQPD #9

Closed mapgccv closed 1 month ago

mapgccv commented 7 months ago

Hello, I'm trying to build the AMPL driver for this interesting solver, but there is probably something I am missing; i'm trying to build without bqpd - as per instructions the library seems to be optional - but I get:

Preprocessing.cpp:(.text+0x1245): undefined reference to `BQPDSolver::BQPDSolver(unsigned long, unsigned long, unsigned long, BQPDProblemType, Options const&)'
/usr/bin/ld: Preprocessing.cpp:(.text+0x132e): undefined reference to `BQPDSolver::solve_QP(unsigned long, unsigned long, std::vector<Interval, std::allocator<Interval> > const&, std::vector<Interval, std::allocator<Interval> > const&, SparseVector<double> const&, std::vector<SparseVector<double>, std::allocator<SparseVector<double> > > const&, SymmetricMatrix<double> const&, std::vector<double, std::allocator<double> > const&, WarmstartInformation const&)'

Cleary if I then add BQPDSolver.cpp to the sources, I get:

/usr/bin/ld: BQPDSolver.cpp:(.text+0x1871): undefined reference to `bqpd_'

which is to be expected, as I don't link with bqpd.

Is there any way to use Uno without it? Thank you!

Hi Christian, Thanks for trying out Uno and for spotting the bug! It should be fixed with commit cdec312e978450f0c73edcf32361f57f46e8af57. Can you give it a try? Best,

Charlie
