Topic: removed --prebuilt-platform

view this post on Zulip Anton (Nov 13 2024 at 18:12):

As of today's nightly the flag --prebuilt-platform got removed. This is only relevant if you are using a platform locally, so not with a url like https://github.com/roc-lang/basic-cli/releases/download/0.16.0/[...].tar.br.

The behavior previously enabled by --prebuilt-platform is now the default. To rebuild the platform (previous default behavior), use the flag --build-host or the flags --build-host --suppress-build-host-warning. Full example:

$ roc --build-host --suppress-build-host-warning examples/platform-switching/rocLovesZig.roc
