Apk compilation requires host lua5.1

For Developers
1

Will need to be updated to reflect a new lua5.1 prerequisite in order to build apk (as of Dec 7 snapshot), or lua5.1 will need to be added as a host tool and included in the SDK.

Otherwise when building packages with the SDK (at least) a failed apk build will fail the package build, when following the advice here:

At least on Debian 13 (Trixie), as it does not have lua5.1 installed by default.

I hesitate to simply edit the Wiki for something this core (besides the decision may be to make it a host tool and include in the SDK).

2

Or.... there is something else going on that resulted in the failure to find the already existing host tool (at ./staging_dir/target-aarch64_cortex-a76_musl/root-bcm27xx/usr/bin/lua5.1): will investigate further.

EDIT: Hmmm....that's not a host tool. I'll have to create a clean environment and get the exact error message, for further debugging.

Nope. It is a missing host tool:

I never did anything explicit to create the host tools though, it's just there after a full make...

Thanks. It looks like it was missed from being included in the SDK then (for include/version.mk:REVISION:=r32228-a90fb76736).
