[Install] Linux AppImage: ld.lld fails to start on non-Ubuntu-22.04 hosts (libicui18n.so.70 missing) #150
Description
Before you continue
- I'm on the latest version (latest WheelWizard, or the latest
MarioKartWiiCompiled-Setup.exefrom the Releases page). - I searched the existing issues and nobody has reported this yet.
- I have a legally obtained copy of the game and it works in Dolphin.
Where does it go wrong?
During compilation / translation
How did you install?
Downloaded the setup exe myself (the WiiCompiled-Setup-x86_64.AppImage v0.2.27 from the Releases page, run from a terminal)
What happens?
./WiiCompiled-Setup-x86_64.appimage install --game ./MarioKart.iso gets through disc validation and translation, then dies at "Configuring the compiler" because the bundled linker cannot start:
/tmp/.mount_WiiComccOGHk/usr/toolchain/bin/ld.lld: error while loading shared libraries: libicui18n.so.70: cannot open shared object file: No such file or directory
Root cause. The lld binary in the official llvm.org Linux release tarball that Launcher/prepare-portable-tools.sh prunes is dynamically linked against Ubuntu 22.04's ICU, and neither the tarball nor the AppImage ships those libraries:
$ ldd squashfs-root/usr/toolchain/bin/ld.lld
libicui18n.so.70 => not found
libicuuc.so.70 => not found
libicudata.so.70 => not found
libz.so.1 => /usr/lib/libz.so.1
...
Every other distro has a different ICU major (Arch/CachyOS 78, Fedora and Debian 13 76, Ubuntu 24.04 74) and no icu70 compat package, so the linker cannot start anywhere but on Ubuntu 22.04 and its derivatives. The other bundled binaries (clang-23, llvm-ar, cmake, ninja) only need the glibc baseline and are fine. The smoke test in prepare-portable-tools.sh does not catch this because the package.yml runner is ubuntu-22.04, which has ICU 70 installed. The aarch64 AppImage is built the same way and should be affected identically.
Workaround. Extract libicui18n.so.70, libicuuc.so.70 and libicudata.so.70 from Ubuntu's libicu70 .deb into a directory and run the AppImage with LD_LIBRARY_PATH pointing at it. With that, the full install completes and check-products reports the base game.
Fix. lld already has a $ORIGIN/../lib RUNPATH, so bundling the ICU libraries into toolchain/lib/ is enough: #151.
