Not compiling with arduino-esp32.git#2.0.1

Final linking fails when using framework arduino-esp32.git#2.0.1

Here are the warnings:

The warnings should not be the cause for not linking. Is there any linking error ?

For the deprecation warning: This has been fixed by e6ee8b2 in the esp-idf. See #7890 for reference

Okay, the linker error is

c:/users/anthony/.platformio/packages/toolchain-xtensa32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: final link failed: bad value collect2.exe: error: ld returned 1 exit status

The large (and only) warning message just made me suspect this library, but it’s a big project so I’ll try commenting out this library (and associated code) and see if it compiles.

It looks like the issue was that arduino framework 2.0.1 is just too new with PlatformIO. following this: espressif/arduino-esp32#5436

Then adding (modifying) the following to my platformio.ini fixed the issue:
platform = https://github.com/platformio/platform-espressif32.git#feature/arduino-upstream
platform_packages = framework-arduinoespressif32@https://github.com/espressif/arduino-esp32.git#2.0.1 toolchain-xtensa32@~2.80400.0

Feel free to close the issue once you see it.

Thanks!
