It appears the built library contains hardcoded absolute file paths and will not run if the directory contents are no longer in the same absolute path they had when they were compiled.

I tested with
https://github.com/rsnemmen/OpenCL-examples/tree/master/add_numbers

after copying the build artifacts from a pc with rocm and a rx 6700xt (rdna 2 architecture) to a steam deck (also rdna 2 architecture) and I get the following error, presumably from the .so file:

LD_LIBRARY_PATH=. ./add_numbers
sh: line 1: /home/USERNAME/Documents/SteamDeck/clvk/build/clspv: No such file or directory

whereas on my steam deck the correct path is /home/steamuser/devkit-game/testing/add_numbers/clspv

Simple_test also fails:

LD_LIBRARY_PATH=. ./simple_test

/home/dk/Documents/SteamDeck/clvk/tests/simple/simple.cpp:76 error after CL call: -11
