Steam Runtime debugging (SDK) environment

SDK container

The default scout/ directory is a version of com.valvesoftware.SteamRuntime.Platform-amd64,i386-scout-runtime.tar.gz from http://repo.steampowered.com/steamrt-images-scout/snapshots/ (see the build ID in its metadata file to find out which one).

To get a debug version of the Steam Runtime container, download the corresponding com.valvesoftware.SteamRuntime.Sdk-amd64,i386-scout-runtime.tar.gz and unpack it into this directory, so that you have this layout:

pressure-vessel/
    ...
scout/
    ...
scout_sdk/
    README.md (this file)
    metadata
    files/
        bin/
            ...
        lib/
            ...
        ...

Then use the developer mode to select the SDK runtime instead of the default Platform runtime.

Older and newer containers

To test beta versions or debug regressions, you can download any recent version of com.valvesoftware.SteamRuntime.Platform-amd64,i386-scout-runtime.tar.gz or com.valvesoftware.SteamRuntime.Sdk-amd64,i386-scout-runtime.tar.gz from http://repo.steampowered.com/steamrt-images-scout/snapshots/ and unpack it into a similar layout, for example:

pressure-vessel/
    ...
scout/
    ...
scout_sdk/
    ...
scout_platform_0.20190926.0/
    metadata
    files/
        bin/
            ...
        lib/
            ...
        ...
scout_sdk_0.20190927.0/
    metadata
    files/
        bin/
            ...
        lib/
            ...
        ...

Steam Runtime schroot

For a fully modifiable version, which requires sudo privileges on a host operating system with the schroot tool:

• Download one of the com.valvesoftware.SteamRuntime.Sdk-amd64,i386-scout-sysroot.tar.gz files from http://repo.steampowered.com/steamrt-images-scout/snapshots/

• Clone https://github.com/ValveSoftware/steam-runtime somewhere convenient

• Import the sysroot tarball as a chroot:

  cd steam-runtime
  ./setup_chroot.sh --amd64 --tarball ../com.valvesoftware...-sysroot.tar.gz
  

• Use sudo schroot -c steamrt_scout_amd64 -- apt-get install ... to install any additional software you need

• Create a scout_schroot directory next to scout and pressure-vessel:

  mkdir scout_schroot
  

• Create a symbolic link to the chroot and name it scout_schroot/files:

  ln -s /var/chroots/steamrt_scout_amd64 scout_schroot/files
  

• The scout_schroot directory should now be available in developer mode
