"missing initializer for member" warning on ESP32, espidf, platformio #1430

Closed codegrue closed 8 months ago

codegrue commented 8 months ago

Problem Description

Compiling on platformio with espidf, this library generates hundreds of these warnings:

.pio/libdeps/project/audio-tools/src/AudioI2S/I2SESP32.h:183:7: warning: missing initializer for member 'i2s_driver_config_t::total_chan' [-Wmissing-field-initializers]

Device Description

ESP32 development board

Sketch

just including the library in any project causes this at compile time

platformio.ini:

[env]
framework = arduino, espidf
platform = espressif32

Other Steps to Reproduce

No response

What is your development environment

VSCode/Platformio, Windows

I have checked existing issues, discussions and online documentation

Please read the documentation in the Wiki and at least indicate why you don't follow the instructions. It would also help if you provide ESP32 Arduino core version that is pulled by your installation: 2.0.14 would be the most recent version!

I'm not sure what part of the wiki you were alluding to, but I reviewed it again and inferred this, which seems to have solved the warnings:

build_flags = -Wno-missing-field-initializers

There is a chapter for PlatfomIO: https://github.com/pschatzmann/arduino-audio-tools/wiki/Working-with-PlatformIO
