[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.

[KrishManohar]

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

[jamesb93]

@KrishManohar No. I gave up on it as a result.

[cheponis]

I get

sh build.sh /usr/local/nim/nim-1.2.6

OS: netbsd

CPU: arm

gcc -o bin/nim -lm
ld: /usr/lib/crt0.o: in function ___start': (.text+0x190): undefined reference to main'
(.text+0x190): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `main'

This has been true for at least 6 months. I have now given up. If they care enough to get the build to work, it does not harken well for the language or its design.

[Araq]

Well you didn't care enough to report it on the correct issue tracker so there is that. Plus it's netbsd which our CIs don't cover. I also don't understand what "programming language design" has to do with "portability", dunno, maybe read a book or something.

[cheponis]

Here's the deal. You want to attract folks into the 'community'. I have the Nim book (was one of the earliest waiting for its publication, got the early MEAPs) and was truly excited to try nim out on various projects; and I have spoken highly about nim at several conferences, based on earlier versions. But, if you can't provide a build that doesn't break (and, I have been writing software for over 40 years), then it's not me who's deficient. This breakage has been true for at least 3 months now, possibly longer. Downloading directly and trying to compile it also fails. I think the snark in your answer proves you do not wish to enlarge the community. Here I am, a real booster, trying to get the damn thing to just compile, and I get shade like this. This proves to me, beyond the shadow of a doubt, that as long as this is the way newcomers who are really trying to become community members, Nim will fail as a community. And how can I know what the correct issue tracker is? This is so sad. Nim had a chance (and still does if Mr. Rumpf adjusts his attitude to be more welcoming, and less scolding). The proper response is: "Darn, sorry about that. Thanks for letting us know. I'll add it to our Issue Tracker, which is where we track bugs. In the meantime, we fully support <X> platform, so if you have <X> available, maybe you can try that until the issue is resolved. Thanks for reporting this!" Something like that. If you don't welcome newcomers, and bend over backward to welcome newcomers, you'll wonder why the nim community is growing so slowly. GL.

The snark in reply is entirely appropriate considering your original post. I don't have to bend over your impertinences.

And yeah, providing bulids that "just work" on 20 different OSes and CPU architectures is hard. Especially if the OS in question I don't use and no CI was setup for it. I bet your 40 year old software doesn't work everywhere either.
