      $ source ~/spresenseenv/setup

$ cd spresense/sdk

$ tools/config.py examples/dnnrt_lenet

$ make

      I tried to build "dnnrt_lenet" in examples through MSYS2 MSYS but encountered the errors as shown below.

      I wonder why the errors happened and how to solve the problem. Thanks!

        Hi, @pgq18-2

        I'm trying to build this example on my side and I'm having issues too.
        Different one though haha

        I'll continue investigating and let you know when I find the solution.

        On the mean time, please check that you have the newest version of the SDK (it has been recently updated). Also, if it's been a long time since your spresenseenv has been configured, try to delete that folder and do the setup again.

          Thanks, @CamilaSouza
          I have no idea what happened, but the problem had been solves after I reinstalled the SDK. Perhaps there was something wrong with the version and configuration.
