Compiler errors with STMCubeIDE 1.13.2 on project for STM32469I-DISCO / 32F469IDISCOVERY

[testcode99]

Using the latest STM32CubeIDE 1.13.2, it's giving errors compiling a STM32469I-DISCO 32F469IDISCOVERY project, i.e. GPIO_EXT example. This project was imported by STM32CubeIDE from STM32Cube_FW_F4_V1.27.1\Projects\STM32469I-Discovery\Examples\GPIO\GPIO_EXTI\SW4STM32.

The 4 errors are like below. Is this a problem with the project or with STM32CubeIDE? Thanks

There was an upgrade to the toolchain with the recent version which is causing these warnings. See here for some good answers on why exactly this is happening:

https://stackoverflow.com/questions/73742774/gcc-arm-none-eabi-11-3-is-not-implemented-and-will-always-fail

At its core, this is probably something that will get resolved in the next STM32CubeIDE version.

As you can see, these are warning, not errors, and the code compiles. You can ignore them if you want.
