Esp32 mongoose-os-modbus-example. mos build errors

#1

Hi.
I’d like to flash my esp32 with modbus-example-master, but when I start building the error appears:

$ mos build --platform esp32

What’s wrong???

Since that example does not belong to the mOS distribution, you sould contact the author.
As far as I can tell, the build log is pretty informative

There is no mongoose-os-modbus directory in your build path; or it does not have the mos.yml file in it
Perhaps you are trying to compile an example without a library referenced by it ?
If you check the mos.yml file in your example, you’ll see it references a local directory for build purposes:

- origin: ../mongoose-os-modbus

and my bet is that you don’t have it or at least it is not where the example expects it to be.

Thanks, for your help!
I changed

origin: …/mongoose-os-modbus

to

origin: https://github.com/mongoose-os-libs/modbus

and the building ended successfully.
