Several QP solvers not available

User Questions

Hi,

I am using the Python interface to work with acados. Everything I tried works fine except that several QP solvers are not available. For instance, if I set ocp.solver_options.qp_solver to ‘PARTIAL_CONDENSING_QPDUNES’ and run the Python script, I get the error message

error: ocp_qp_xcond_solver_config_initialize_from_plan: unsupported plan->qp_solver
This might happen, if acados was not compiled with the specified QP solver.

When I try ‘FULL_CONDENSING_QPOASES’, I get

cannot find -lqpOASES_e

Did I miss something in the installation of acados?

Hi,

as the error message says, you need to install acados with the corresponding QP solver.
Did you do that?

It is described here: Installation — acados documentation

# add more optional arguments e.g. -DACADOS_WITH_OSQP=OFF/ON -DACADOS_INSTALL_DIR=<path_to_acados_installation_folder> above

Are the libs build successfullly?

Thank you. I will re-install it.
