[warning] module cffi/niri-taskbar: Disabling module "cffi/niri-taskbar", Failed to initialize C ABI module #18
Description
I've built & installed waybar from source, straight from git.
I've built and installed the niri-taskbar with the following recipe:
# Description: niri module for waybar
# URL: https://github.com/lawngnome/niri-taskbar.git
# Dependencies: waybar gtk3+-devel
name=niri-taskbar
version=git
release=1
source=(
https://github.com/lawngnome/niri-taskbar.git
)
build()
{
cd $name
command -v cargo >& /dev/null || export PATH=$PATH:$HOME/.cargo/bin
cargo clean
cargo build --release
install -m 555 -D target/release/libniri_taskbar.so $PKG/usr/local/lib64/libniri_taskbar.so
}
Configured waybar like so:
head /home/han/.config/waybar/niri
{
"cffi/niri-taskbar": {
"module_path": "/usr/local/lib64/libniri_taskbar.so",
"notifications": true,
"show_all_outputs": true,
},
"layer": "top",
"position": "top",
"height": 17,
"modules-left": ["cffi/niri-taskbar"],
...
And running waybar goes like this:
% <main> /usr/local/bin/waybar -c /home/han/.config/waybar/niri
