micro_ros_arduino RP2040 Connect build trouble SPI.h not found?

edit

Hello All, as much as I hate to admit I'm officially stuck. Thanks for any help you can offer.

I have been trying to get micro_ros_arduino to build as per the docs located here: https://github.com/micro-ROS/micro_ro...

However I still cannot build anything. Does this rely on any libraries installed with the Arduino IDE?

My testing main.cpp is just a blink sketch that works fine otherwise with PIO. It has no other code.

My platoformio.ini is setup per the docs but I get build errors that claims it cannot find SPI.h (see below)

What I have tried.

Adding SPI manually in a few different ways.

• putting arduino-libraries/SPI as a lib_dep simply reported that the library was built in and not needed.

• Adding SPI as a lib_dep

• lib_ignore SPI

  Results: Build got past SPI not found error but build then spits out some initial warnings regarding WIFi (captured below) then about 500+ more lines of warnings from libmicroros and then fails with collect2: error: ld returned 1 exit status
