Fleet Provisioning build error (CA-331)

[amitabhskrishworks]

Hello there,
I have cloned the esp-aws-iot folder using the "https://github.com/espressif/esp-aws-iot.git" .Without making any changes I tried to build the fleet_provisioning_with_csr example (given at: esp-aws-iot/examples/fleet_provisioning/fleet_provisioning_with_csr) but got stuck with build errors (mentioned below) but was able to build the mqtt/tls_mutual_auth example. Although both the examples are in same folders but i don't know why is fleet one not working.

I also encountered the same problem, have you solved it?

Hi @amitabhskrishworks
Issue is due to maximum filename limitation in Windows filesystem.

Can you try enabling longpaths on your Windows as instructed here.

If this doesn't work as well, can you try placing esp-aws-iot somewhere in C:\ directly for now? We will see how we can shorten the filepath of the object file for Windows. Unfortunately. we don't have a way around it as of yet.

Or else you can just change the name of "Fleet-Provisioning-for-AWS-IoT-embedded-sdk" to "Fleet-Provisioning".

This is easy and best solution if enabling long path does not work

[amitabhskrishworks]

If change the branch to any of these then it works
release/202012.04-LTS
release/202210.01-LTS

This solution worked for me
Thank you
