Pei Yang Ching (Feb 19 2024 at 00:17): Pei Yang Ching (Feb 19 2024 at 00:17):Hi! I'm looking at the example platforms in platform-switching, but I don't understand how roc build can magically detect and compile platforms in C, zig etc. as far as I can see there's no build file, are they hard coded?
how can I modify the build step? for example, in a C platform how do I use a shared lib, include a header, etc.
I've seen an example of compiling the platform and then the roc app separately with --no-link, but I'm wondering if there's a standard way to all this
Brendan Hansknecht (Feb 19 2024 at 00:20):The build system is mostly a hack rn in the link.rs file.
Brendan Hansknecht (Feb 19 2024 at 00:21):If you need more control, you have to use --no-link and then have another build system deal with things.
Pei Yang Ching (Feb 19 2024 at 00:22):ah I see, thanks for the quick reply
Brendan Hansknecht (Feb 19 2024 at 00:22):Long term, we plan to have platforms have their own build scripts. They will compile into a special format that enable roc to deal with all the rest of the linking without knowing anything about the language the platform is written in.
