Any hints? EDIT: The above comment from LEONIDAS solved this build error :)

dhathaway, did you figure it out ?

I am getting a build error. Any hints on how to resolve?

(Wow, the markdown is remarkably ugly.)

Something has happened to the 3rdparty/ultravnc repository that veyon refers to. I get the following when trying to install.

Version 4.3.5 is out and works fine. Could you please update?

With the recent glibc veyon has to be recompiled, otherwise there will be coredump created! Veyon 4.3.4 has still some compatibility issues: https://github.com/veyon/veyon/issues/626
