Which esp-idf version to compile with?

[tommytamsen]

I've tried to compile under WSL2 (Windows Subsystem for Linux 2) using different esp-idf versions going down from version 3.x.x all the way back to esp-idf v0.9.
Every time I get errors. This is the output from compiling with esp-idf v0.9

Do you by any chance remember which esp-idf is the best for this project?

Finally figured it out! Just ignore this...
