The compiler cannot find the required C compiler to build the underlying graphics and OS code.
Did you follow the getting started to ensure the dependencies were all installed? https://docs.fyne.io/

Hello, I have installed the detection software and all the tests have passed, but I still can't run the demo

This is the error message

[andydotxyz]

It cannot find the compiler wherever you executed the build. The environment must not be the same as the system environment. Try a different shell/terminal - it looks like either it has been customised or that one isn't picking up the system config.

fyne-cross uses docker or podman to run containers - if neither are installed it cannot proceed.

If you are manually specifying OS instead of using our packaging helpers you must specify CC as well and point to the C toolchain, as well as CGO_ENABLED=1 - see docs at https://docs.fyne.io/started/cross-compiling.
