I managed to compile gmpublisher and I'd like to share this feat with you!

So far I had no crashes and my mouse input is fine (#102).

Much better than that: "My workshop", "Installed addons", "Downloader" and "Addon size analyzer" work as expected :)

So right below are my installation steps, but be warned that some may be wrong or unnecessary as everything here is new to me!

# Install Tauri requirements (Rust + linux packages)
# https://tauri.app/v1/guides/getting-started/prerequisites

# Install nodejs https://nodejs.org/en/download/package-manager

# Download steam sdk version 151 https://partner.steamgames.com/doc/sdk
# unzip it into your Downloads folder

sudo apt install libgtksourceview-3.0-dev clang

sudo npm i -g corepack

sudo corepack prepare yarn@stable --activate

git clone https://github.com/WilliamVenner/gmpublisher.git

cd gmpublisher

git checkout tags/2.9.2 # Don't execute this command if you want to use the latest version, but this guide only covers 2.9.2

npm i -f # Force to install fsevents

yarn install

npm run build

cd src-tauri/

# in Cargo.toml add this line after [dependencies]:
openssl = { version = "0.10", features = ["vendored"] }

STEAM_SDK_LOCATION=~/Downloads/sdk cargo build --release

cd target/release

# Install gmpublisher in your system:
sudo cp gmpublisher /usr/bin
sudo cp libsteam_api.so /usr/lib

# Execute it:
gmpublisher

Extra 1 - My binary (64 bits) & how to run it

I'm not sure if my compiled files can be used by you, but here they are:
gmpublisher.zip
(test the links with the ldd command)

To run my compiled gmpublisher you need to unzip the files to ~/Applications/gmpublisher and execute this command:

cd ~/Applications/gmpublisher
LD_LIBRARY_PATH=~/Applications/gmpublisher ./gmpublisher

Or add gmpubliser to the system like I did after compiling it:

cd ~/Applications/gmpublisher
sudo cp gmpublisher /usr/bin
sudo cp libsteam_api.so /usr/lib
gmpublisher

Extra 2 - Create a system shortcut

Save this icon

as ~/.local/share/icons/hicolor/256x256/apps/gmpublisher.png

If you're using a distro link Linux Mint, you can create the shortcut with a tool like this one:

Or just go ahead and create the file manually:

Copy this text (change the YOURUSERNAME value) (I'm assuming you installed gmpublisher in the system):

[Desktop Entry]
Type=Application
Name=gmpublisher
Exec=/user/bin/gmpublisher
Icon=/home/YOURUSERNAME/.local/share/icons/hicolor/256x256/apps/gmpublisher.png
TryExec=gmpublisher
Comment=A powerful and feature-packed Workshop publisher for Garry's Mod!

And paste it into ~/.local/share/applications/gmpublisher.desktop (create this file)

Now just run this command:

sudo chmod +x ~/.local/share/applications/gmpublisher.desktop

Ta-da!

(restart your session if the icon doesn't appear)

I feel like Linux is better covered now.
