ESP32Cx versions do not compile at my desk

[Mape24]

At Building with this setting env:tasmotaESP32c... I get this bug:

riscv32-esp-elf-g++: fatal error: cannot execute 'c:/users/moppel/.platformio/packages/toolchain-riscv32-esp/bin/../lib/gcc/riscv32-esp-elf/12.2.0/../../../../riscv32-esp-elf/bin/as.exe': CreateProcess: No such file or directory

• The mentioned folder does exist!
• error appears at first call of riscv32-esp-elf\bin\as.exe
• other tools like bin\riscv32-esp-elf-c++.exe run successfully before this error
• no problem with env:tasmotaESP32s2 or with env:tasmota target
• no problem with other (none Tasmota) PlatformIO example using ESP32C3

I have actually not found , where the tool folders are defined and configured. Can you help?

Regards Marten

Your Platformio setup seems broken. Close VSC. Delete hidden folder .platformio Start VSC. Wait, Platformio does rebuild. Do the restart when you asked for.

[Mape24]

Yes, I did that already. I have red this hint before. It took me 1 hour, but it did not help.
However, I have a fresh setup now.

My PlatformIO works well for other PlatformIO projects using ESP32C3.

Is your system Windows based? In this case you run probably in the Windows path length limit.
You may can workaround by uncomment the lines 11 - 16 in platformio_override.ini

Thank you! Windows path length limit was the reason.
Your suggestion to modify platformio_override.ini puts the built folder into c:/ root folder in order to keep the path names short.

core_dir = .platformio
workspace_dir = c:\.pio

(new installation of pio takes 30 min)

Probably there is another solution.
Start windoes REGEDIT and select
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
set LongPathsEnabled. 1

This I havent tried yet.
