how to add Arduino as component using esp32-arduino-lib-builder?

[gdanov]

using the manual https://docs.espressif.com/projects/ard ... onent.html I get Arduino as component working and that's great. However I don't want to checkout the arduino git repo in each project or build it every time I touch the sdkconfig.

The manual says "For a simplified method, see lib-builder.", but I can't figure out how to use the results once I build this project.

I guess that section https://docs.espressif.com/projects/esp ... components applies, but my cmake and C knowledge is not enough to figure it out.

For the 'checkout per dir', you could check out the Arduino stuff in one directory, and then for each project that uses it, add

Code: Select all

set(EXTRA_COMPONENT_DIRS /home/me/whereever/the/arduino/component/dir/is)

to CMakeLists.txt.

Thanks, I'll give that a try.

What are my options to minimize re-compilations of the Arduino component? I'd like to re-build the arduino component only when I touch something relevant in the sdkconfig. I'm pretty fine with a manual process (e.g. configure, build, copy something somewhere)

I don't think you can get around an entire rebuild when you touch the sdkconfig. If you leave the sdkconfig alone, the Arduino code should not be recompiled though.

I could use it as pre-compiled lib. But still can't figure out where's the arduino.a or how to include it.

Using ccache btw and the speed-up is impressive.
