can't get code generator to work on my machine #744

Closed thomas725 closed 1 year ago

thomas725 commented 1 year ago

I've got a clone of this repository (https://github.com/fzyzcjy/flutter_rust_bridge) checked out & up to date @129cafa261c1377ed36685e41ccb7e9330e7614a.

When I run flutter run -d linux in the frb_example/with_flutter/ subfolder, it works fine.

But after I run the code generator (in the repositories root folder) it stops working.

Output of code generator:

Error I get with the locally generated code:

More verbose error printed when trying to run with CLI:

Can you help me? Are those warnings about missing modules web & io at fault? I've got very similar problems with https://github.com/Desdaemon/flutter_rust_bridge_template

Ah sorry I've been missing the export CPATH="$(clang -v 2>&1 | grep "Selected GCC installation: " | cut -d' ' -f4-)/include" in the terminal session I've used, with that the example included here works fine again. My problem with the template seems to have a different cause: https://github.com/Desdaemon/flutter_rust_bridge_template/issues/16
