Error while compile firmware (xtensa-esp32s3-elf-g++: error)

[Brunes]

Hello,

I'm encountering an issue while building the firmware for the Heltec Wireless Tracker on Windows. The error message is:

Compiling .pio\build\heltec-wireless-tracker\src\platform\extra_variants\heltec_wireless_tracker\variant.cpp.o
xtensa-esp32s3-elf-g++: error: CreateProcess: No such file or directory
Compiling .pio\build\heltec-wireless-tracker\src\serialization\cobs.cpp.o
*** [.pio\build\heltec-wireless-tracker\src\platform\extra_variants\heltec_wireless_tracker\variant.cpp.o] Error 1

I have tried several troubleshooting steps:

• Verified the toolchain installation and the availability of xtensa-esp32s3-elf-g++.
• Cleaned the build directory and reduced the project path length.
• Added linker flags (--gc-sections, --relax) to optimize the build process.

Could anyone provide guidance or suggestions to resolve this issue on Windows?

Thank you in advance for your help! 😊

If you're happy with a 200kb bigger firmware file then you can remove the -flto flag in your local dev setup. Then this windows error should not occur anymore.
