Build on Ubuntu 22.04 failed

[petr-fischer]

I have no idea what's going on - an incompatible version of webkit? Do you need another debug output? Send me the commands.

If I try to compile this:

require "webview"

wv = Webview.window(640, 480, Webview::SizeHints::NONE, "Hello WebView", "http://crystal-lang.org")
wv.run
wv.destroy

following error occurs:

Seems you have missing dependencies. Can you please check your system if you have libgtk-3-dev installed?

sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev

[petr-fischer]

Yes, I had both already installed.

[naqvis]

Can you run below command to ensure pkg-config is able to find these dependencies?

pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0

[naqvis]

I don't have access to Ubuntu 22 box, so unable to reproduce. You can try to install original library https://github.com/webview/webview or any of its bindings to validate if its dependencies issue or anything specific to this binding.

[sourceweaver]

@petr-fischer I've had the same issue with Debian 11, the suggested fix in #4 has worked for me. After you download the library with shards install, edit the local copy of lib.cr and find the lines:

https://github.com/naqvis/webview/blob/d302ffaf84b51e31a3eced48e188cbc5faafe6e3/src/lib.cr#L6-L7

And re-order these annotations to be:

@[Link(ldflags: "`command -v pkg-config > /dev/null && pkg-config --cflags --libs gtk+-3.0 webkit2gtk-4.0`")]
@[Link(ldflags: "#{__DIR__}/../ext/libwebview.a -lstdc++")]

After this tweak, you should be able to compile your program.

For @naqvis:

It looks like #4 and #11 are connected, and the fix seems to have helped others. Do you think this change should be made upstream?

[petr-fischer]

After this tweak, you should be able to compile your program.

Yes! That works - thanks.

[naqvis]

@sourceweaver appreciate if you can push a PR with above fix.
