AppImages are portable software that do not require root permission to be run. They can be run without root permission:
chmod +x ExamplePackage.AppImage
Most AppImages require sys-fs/fuse on slot 0:
dlopen(): error loading libfuse.so.2 AppImages require FUSE to run. You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option. See https://github.com/AppImage/AppImageKit/wiki/FUSE for more information
This error can be solved by installing sys-fs/fuse in slot 0. Slot 0 has version 2 of fuse required by most AppImages. Whereas sys-fs/fuse in slot 3 which has version 3 of fuse. The highest version available is installed by default, currently in slot 3, if no slot is specified and doesn't solve the dependency problem.
emerge --ask sys-fs/fuse:0
This guide provides instructions for creating an AppImage of ripgrep, a line-oriented search tool that recursively searches directories for a specified pattern. The AppImage allows you to run ripgrep on compatible Linux systems without the need for installation.
Usage: Follow the steps below to create the ripgrep AppImage:
Step 1: Set up your build environment
Make sure you have the necessary tools and dependencies installed on your system, including gcc, cmake, pkg-config, and appimagetool.
Step 2: Clone the ripgrep repository
git clone https://github.com/BurntSushi/ripgrep.git
Step 3: Navigate to the ripgrep directory
Step 4: Build ripgrep
cargo build --release
Step 5: Install the AppStream CLI (optional)
If you want to include AppStream metadata in your AppImage, you can install the appstreamcli tool. This step is optional but recommended.
Step 6: Create the AppDir
Create the AppDir using appimagetool with the following command:
Step 7: Copy ripgrep files
Copy the ripgrep binary and any necessary files to the appropriate locations within the AppDir. Use the following commands:
cp target/release/rg squashfs-root/usr/bin/rg
Step 8: Create an AppRun file
Create a file named AppRun within the AppDir and make it executable. Add the following content to the file:
#!/bin/sh exec "$(dirname "$0")"/squashfs-root/usr/bin/rg "$@"
Step 9: Set permissions
Ensure that the AppRun file is executable by running the following command:
chmod +x squashfs-root/AppRun
Step 10: Generate the AppImage
Finally, generate the AppImage using appimagetool with the following command:
After following these steps, you will have an AppImage file named something like ripgrep-x.x.x-x86_64.AppImage, where x.x.x represents the version number of ripgrep.
This AppImage can be distributed and run on compatible Linux systems without the need for installation.
