All required dependencies are installed

Same here, Fedora 41, astal 0.1.0, ags 2.2.2.

I grepped the whole astal and ags projects, the errror is not found in one of these projects, maybe in a dependancy ? No idea how to debug that.

[jascii]

I was able to solve this problem by installing the dependencies of package.json with npm install and then adding the -p flag to the ags bundle command in meson.build.

Now everything runs fine. @ctaque hope this will help you too. If so you can close this issue

[ctaque]

Well,

Althrough I installed astal, I have no directory /usr/share/astal as pointed out by the astal dependency in package.json.

Any idea how to solve that ?

Thanks in advance

Since you are using Fedora, I assume you are compiling astal from source code. If /usr/share/astal/gjs is not present, you seem to have forgotten to install the libraries.

https://aylur.github.io/astal/guide/getting-started/installation#building-from-source

I had to execute for all the libraries individually

cd /tmp/astal/lib/astal/$library
meson setup --prefix /usr build
meson install -C build

I have installed gtk3, gtk4 and io :

Seems that lib64 is the 64bit library directory in fedora.

Nethertheless I still don't have the /usr/lib64/astal/ directory

[jascii]

Ok

cd astal/lang/gjs
meson setup --prefix /usr build
meson install -C build

installs for me astal to /usr/share/astal/gjs. What is it doing for you?
