[webmacaque]

The same here; doesn't compile with same errors

[idlewan]

Try with passL = "-lui" in examples/nim.cfg. That solved it for me (on Archlinux).

[freevryheid]

also on arch:
yaourt libui or libui-git
nim -d:useLibUiDll c test.nim

[Peter2121]

I have the same problem on Mac OS X, ui installed by nimble - cannot build examples, linker does not find _ui* functions.

[dom96]

Works for me. Can you show us what commands you've tried?

[jamesb93]

I am also (basically) on a fresh install and cannot compile the UI examples. I installed libgtk3+ via brew and this is my errors in compilation.

@jamesb93 did you ever found a solution on this? I am also on macos. 10.15 I did brew install.
