Hi,
While installing Platformio on my Raspberry Pi, I ran into problems with the ESP32 toolchain.
The error message referred a missing CXXABI 1.3.9 entry in libstdc++.
It appears that Raspbian 8 (Jessie) is incompatible with the ESP32 environment because the highest level of CXXABI supported is version 1.3.8.
Raspbian 9 (Stretch) appears to be working.
This may be due to Raspbian Jessie supports up to gcc 4.9 while Raspbian Stretch supports gcc 6.3
What exact PIO command did you run and what exact error message did you receive?
pi@RPi3B7:~ $ pio init --board lolin32;pio run -e lolin32
