Problem compiling for zephyr platform

[naichenzhao]

I am trying to compile the code for zephyr on 0.5.2-SNAPSHOT and it seems to be looking for a file (CompileDefinitions.txt) that doesn't seem to exist.

(base) naichenzhao@Naichens-MacBook-Pro application % west lf-build src/Blinky.lf -w "-b nucleo_f446re -p always"
Executing lfc command: `lfc -c -n src/Blinky.lf`

Thanks a lot for reporting this @naichenzhao. I had forgotten to update the lf-west-template. Please check out the most recent commit, and the documentation-update here: lf-lang/lf-lang.github.io#174

In short, you should pull the most recent commit from lf-west-template replace your command with:

west lfc src/Blinky.lf --build "-b nucleo_f446re -p always"

And it should work. Please let me know if you run into other problems.

[erlingrj]

Could you try building the examples again with the up-dated docs and lf-west-template repo @naichenzhao ?

[naichenzhao]

I re-downloaded the nightly version of lfc. Im not sure if its an issue on my end, but it seems I am getting a different error.

[erlingrj]

I have changed the layout of lf-west-template now. So the example apps should be located in:
apps/HelloWorld/ and apps/NrfBlinky. It looks like you have the old structure? Could you try pulling the latest version of lf-west-template and use the newest project layout. The command to run, from the root of the repo would be:
west lfc apps/HelloWorld/src/HelloWorld.lf --build "-b nucleo_f446re -p always"

See here for the most up-to-date docs. Please let me know if anything is unclear in them.

[naichenzhao]

Yeah, that's my bad. It works now, thank you very much.

Thanks for the fixes, @erlingrj, and thanks for confirming, @naichenzhao.
