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
The Github macOS runner has several tools installed:
https://github.com/actions/runner-images/blob/main/images/macos/macos-13-Readme.md
It would be nice if you could figure out how you have to configure the
rtems-tools build so that it finds an LLVM installation providing
Symbolize.h on macOS.
In the Github job, I added the LLVM 17 installation from brew to the $PATH:
export
PATH="/System/Volumes/Data/usr/local/Cellar/llvm/17.0.6/bin:$PATH"
./waf configure
./waf
sudo ./waf install
Without the patch, the build fails:
https://github.com/embedded-brains/rtems-tools/actions/runs/7602490988/job/20703105123
With the patch it works:
https://github.com/embedded-brains/rtems-tools/actions/runs/7602509162/job/20703139110
Does XCode ship a Symbolize.h and llvm-config? If yes, how do you get
the tool in the $PATH?
