I tried to look up the error, and came across the following link. I don't know if this helps or not.

Should be now fixed in branch 1.7.1

I didn't see a release for 1.7.1, so I did git clone https://github.com/jvirkki/dupd and make compiled without error.

I hope I did it correctly. Thank you

I hadn't tagged 1.7.1 as a release yet, it is now done.

If you clone the master branch, that's the ongoing development code. It should likely work, but it is not a released version.

If you need a stable version, best to build from a release tag instead.
