@andrewtbarker Could you please take a look at the issue reported in 2021 ?

[andrewtbarker]

@vrpascuzzi @aelizaro Is this easy to fix or should we just document that we do not support this combination?

[vrpascuzzi]

@andrewtbarker It's been a few years since I worked on this, but IMO the combination should be supported.

Can the libraries be linked and used together in an application? (Are the tests faulty?)
