I have tried building different versions of Qt from 5.11 to 5.13, both with static and dynamic linking, yet result is always the same: whenever I try to run cross-compiled app I am only getting Could not initialize egl display error.
What i have tried so far:
- building different versions of Qt <- no effect
- running app with -platform eglfs args <- no effect
- export DISPLAY=:0 before running application <- no effect
- running examples from /opt/vc/hello_pi/ <- they all work just fine
- enabling/disabling Full KMS OpenGL driver <- no effect
- running with sudo <- adds QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' before error

Note: Using static linking will disable the use of dynamically
loaded plugins. Make sure to import all needed static plugins,
or compile needed modules into the library.
WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.
Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.
