</div>
<div>Has anyone successfully run Ipopt with the MUMPS solver using the packages provided on Ubuntu?</div>

<div>I am able to successfully run the Cpp_example.cpp when I compile Ipopt and Mumps from source.</div>
<div>However, when I use the Ipopt and Mumps packages provided by the package manager I get the following runtime error:</div>
