Revery: esy build fails on Ubuntu 18.04.1 LTS

[sslotsky]

Amazing project, very excited to build some apps with it! Sadly, build fails with the error below. I've installed all packages listed in the README. I searched for the error and saw a suggestion to install libgtk2.0-dev or libgtk-3-dev. Neither of these resolve the error but perhaps I'm missing something from my $PATH?

@sslotsky thanks for reporting this :+1: , I recently added the initial bits for using gtk (#294)for native widgets which has gtk as a dependency. I assumed that most linux distros bundled gtk especially ubuntu which uses gnome by default :thinking:

Can I ask what happens when you run pkg-config --cflags gtk+-x11-3.0 if it prints out a list of directories do those exist if so the build should be working :face_with_head_bandage:, also installing gtk-3 didn't work?

[sslotsky]

Thanks for the reply! Looks like I get a list of directories indeed

sam@sam-ThinkPad-T480s:~/revery$ pkg-config --cflags gtk+-x11-3.0

I didn't check every folder but the first few I try certainly do

I had the same build error on Ubuntu 19.04 (also had to install libgtk-3-dev). Removing the _esy folder and then running esy install and esy build got me further.

I then got the following build error:

which was fixed by removing ~/.esy and running esy install and esy build. Now the project builds correctly.

@sslotsky did you have a chance to try out @expe's solution of clearing the _esy directory and rerunning the esy command?

[sslotsky]

Ahhh, sorry for the delay on this! I just now tried it and yes, it worked! :fire: :fire: :fire:

Thanks so much for finding and sharing this workaround @expe !!

[akinsho]

Nice :+1: closing this as there's a solution and the issue was resolved

[kifirkin]

@Akin909 I think this solution https://github.com/revery-ui/revery/issues/316#issuecomment-462505096 should be documented, also libgtk-3-dev added to Debian/Ubuntu dependencies

[JasoonS]

https://github.com/revery-ui/revery/pull/345 <- this is also an issue for ubuntu <=18.04.

I'll document it in the readme.
