Not able to build subscribe_publish example for ESP32C3 target (CA-163)

[jitendraBLE]

Hi All

I have ESP32C3 chip and want to build subscribe_publish example project for ESP32C3 target. When I set target esp32c3 using "idf.py set-target esp32c3" command and build the project I got following error:

riscv32-esp-elf-gcc: error: unrecognized command line option '-mlongcalls'

I read the espressif document which says esp-aws-iot sdk project is available for ESP32C3 target. Following link is for reference but it redirect to me on same project which I already tried to build for esp32c3 and it's gave above build error.

https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/libraries-and-frameworks/cloud-frameworks.html

Any help will be appreciated. Thanks

For any such build errors, the following steps generally help

• Ensure all esp-idf submodules are in sync by executing git submodule update --init --recursive in esp-idf.
• Re-run ./install.sh and . ./export.sh in esp-idf
• Remove the build and sdkconfig in project using rm -rf build/ sdkconfig sdkconfig.old
• Restart from idf.py set-target esp32c3

Thanks Piyush for your quick response.

Does subscribe_publish example in esp-aws-iot repository works for ESP32C3 target?
