MangoHud does not work across stratums

[Cervoxx]

Summary

If you try to use mangohud on an application in a different stratum, it will throw this error

ERROR: ld.so: object 'libMangoHud.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

This does not occur if both programs are in the same stratum.

Details

• To reproduce (and how I have my setup working): Fetch arch, enable multilib, install yay, install mangohud via yay, then prepend mangohud to any program from another stratum you want a hud for, such as vkcube or glxgears. Ex: mangohud glxgears However, you can also reproduce the issue with the binary from the releases page of mangohud.

• Mangohud github page: https://github.com/flightlessmango/MangoHud

• If you look at the page, you can see an env var option to setup logging output_file, this is for fps logging. Not debug logs.

Was not aware that this type of issue was caused as a result of unsupported cross-stratum libraries. Closing.
