RE: Editing MakeFile

Hi,

There is no way to do this directly in the Makefile, but you can create a script for it.
The easiest way to get a list of warnings and errors is to store the build log into a file, for example:

west build -b nrf52840dk_nrf52840 > build_output.log

Then you can use grep to find how many times "warning" and "error" shows up in the build log, for example:

echo "Warnings: $(grep -i ": warning" build_output.log | wc -l)"
echo "Errors: $(grep -i ": error" build_output.log | wc -l)"

To get the time, you can use the time command when building:

time west build -b nrf52840dk_nrf52840

If you create a script for building, you can get the time before and after building and output this.
Here is an example script that prints out warnings, errors, and time:

#!/bin/bash

start=$(date +%s)
west build -b $1 > build_output.log
end=$(date +%s)

duration=$((end - start))

warnings=$(grep -i ": warning" build_output.log | wc -l)
errors=$(grep -i ": error" build_output.log | wc -l)

echo "Warnings: $warnings"
echo "Errors: $errors"
echo "Build time: $duration seconds"

This takes the board as an argument when running the file, so if the file is called count_build_issues.sh you can run it to build for nRF52840 DK as follows:

./count_build_issues.sh nrf52840dk_nrf52840

Best regards,
