ESP32 Compilation Warnings

[mnfisher]

A little tip to make life easier.

The output from the esp32 compiler is a 'little' verbose. It is possible to turn off some of the warnings.

In your project directory/main

Edit CMakeLists.txt

At the end of the file add:

Code: Select all

target_compile_options(${COMPONENT_LIB} PRIVATE -Wno-unused-variable)
target_compile_options(${COMPONENT_LIB} PRIVATE -Wno-unused-function)
target_compile_options(${COMPONENT_LIB} PRIVATE -Wno-int-conversion)

This will turn off unused variable and function warnings as well as conversion between integer types. Obviously you should aim to tidy up the code that gives these messages - but it makes spotting the error 'needle' easier in the early project haystack...

Other warnings can be disabled using similar syntax....
