This patch fixes bugs #4908 and #4965 which were reported by RTMES
users.  The patch is from 19 May 2023 and was blocked due to missing
tests on macOS.  I have no macOS system for tests.  Would someone mind
testing this patch?  It would be nice to build the RTEMS Tools on modern
Linux systems with a standard LLVM package.

I added a simple CI script to our Github fork of rtems-tools:

https://github.com/embedded-brains/rtems-tools

It seems that the current tools build with LLVM installed on ubuntu-latest event without the patch:

https://github.com/embedded-brains/rtems-tools/actions/runs/7580906673

It builds also with the patch:

I installed LLVM on macOS using brew, however, the rtems-tools didn't pick it up. How can I build the rtems-tools on macOS with LLVM support?

I'm willing to spend some time testing stuff on macOS.

Thanks for having a look at it.


However, I don't really understand why you installed LLVM using brew: people on MacOS usually use the standard XCode compiler from Apple, which is itself based on LLVM.

I don't use macOS myself, so I have no idea how this is set up normally. It would be great to have the standard approach available as a Github workflow.


What needs to be tested exactly?

The rtems-tools need to be built with the LLVM support. For this ./waf configure needs to find LLVM. If it works it prints out something like this:

Checking for library LLVM                : yes
Checking for header llvm/DebugInfo/Symbolize/Symbolize.h : yes
Checking for header zlib.h                               : yes
Checking for library z                                   : yes
Checking for library ws2_32                              : not found
Checking for compiler flags -std=c++20                   : yes
