Getting help

If you need help, please ask a question on the JuMP community forum.

If you have a reproducible example of a bug, please open a GitHub issue.


Install DSDP as follows:

import Pkg

In addition to installing the DSDP.jl package, this will also download and install the DSDP binaries. You do not need to install DSDP separately.

To use a custom binary, read the Custom solver binaries section of the JuMP documentation.

Use with JuMP

To use DSDP with JuMP, use DSDP.Optimizer:

using JuMP, DSDP
model = Model(DSDP.Optimizer)

MathOptInterface API

The DSDP optimizer supports the following constraints and attributes.

Compile your own binaries

In order to compile your own libdsdp.so to be used of DSDP.jl, use the following

OB_DIR=$(julia --project=. -e 'import OpenBLAS32_jll; println(OpenBLAS32_jll.OpenBLAS32_jll.artifact_dir)')
OB="-L${LIBOB_DIR}/lib -lopenblas"
make DSDPCFLAGS="-g -Wall -fPIC -DPIC" LAPACKBLAS="$OB" dsdplibrary
make DSDPCFLAGS="-g -Wall -fPIC -DPIC" LAPACKBLAS="$OB" SH_LD="${CC} ${CFLAGS} -Wall -fPIC -DPIC -shared $OB" oshared
