Barto22 opened a new issue, #16775:
URL: https://github.com/apache/nuttx/issues/16775
### Description / Steps to reproduce the issue
I created a simple C++ application using C++20 features and wanted to use
the C++ library from the ARM toolchain. I’m using the latest ARM toolchain
version 14.3.1. The target platform is STM32F4Discovery, with the build
configuration set to testlibcxx.
In menuconfig, I changed the C++ Library option to "Toolchain C++ support"
because the LLVM C++ library produced some errors (which I’ll address as a
separate issue).
When compiling, I encounter the following errors:
