That’s a great place to start looking, thanks. I think what I’ll first attempt to do is just brute-force my way into that, just to see what happens, and get it at least trying to use the cross-compiler given, ‘arm-(device)-linux-gnueabi-’ and see what happens. There is a bitbake layer to build clang to cross compile for the device, though we aren’t currently using it, and not sure if it works. We’ll at least suss out some potential gcc issues.
Ultimately, I’d probably want to add a new piece to the ToolChain support in UBT, and contribute that if there’s no issues from the customer with contributing back.
