I can not understand what is going on this project?

see https://github.com/ClausKlein/execution/actions/runs/15373746732/job/43256183253#step:5:121

Some of my checks are deleted?

The build fails on OSX?
see #153

The installed version is not usable:

bash-5.2$ cmake -B build -S .
CMake Error at CMakeLists.txt:17 (find_package):
  Could not find a configuration file for package "beman.execution" that
  exactly matches requested version "0.0.2".

  The following configuration files were considered but not accepted:

Do you know why this code was removed and what the konsequences are?

... den sie wissen nicht was sie tun!

Similar to my previous comment, I admit that I don't understand what this test tries to achieve. In my development it was always executed (and I haven't figured out, yet, why) and took a substantial amount of time.

with bemanproject/exemplar#173 this variant, only examples are used.

-
-if(PROJECT_IS_TOP_LEVEL)
-  find_package(beman_execution 0.0.1 EXACT QUIET)
-  if(beman_execution_FOUND)


... den sie wissen nicht was sie tun!

I do understand the German but I don't quite understand the implication. I admit that I don't understand what that is trying to achieve. There is certainly no equivalent logic in the exemplar version of the file. Explicitly testing for a version number seems ill-advised, though.

see bemanproject/exemplar#173

At C++Now we had multiple discussions on the build infrastructure. The general consensus was (is?) that Beman projects should have mainly identical builds: the overall development should happen on the exemplar and/or infra repository(-ies). There are multiple parties interested in getting build right, including people from Kitware who can change cmake if changes are needed/useful (and representatives from, at least, one Kitware client who may ask them to do so).

The current PR is a draft bringing execution in line with the [current] exemplar structure. At least my hope is that we eventually arrive at a setup which is shared between projects with the only differences being the name and the list of entities being build.

Some of my checks are deleted?

Yes: see above. If the checks are useful/necessary I think they should be present in all Beman projects alike. While consistency was (is) the main driver, a secondary reason for me was that the find-package-test always took a substantial amount of time as it ran every time I built execution. When trying to confirm that this would still be the case I noticed that the test is not run if I just restore it (if the test isn't run all the time I'll restore it , assuming a corresponding test will emerge in exemplar).

The build fails on OSX? see #153

It most certainly doesn't when I build on my local machine(s) (I'm developing on Macs) or in the CI github. However, these use Apple's /usr/bin/clang++ when building rather than a recent LLVM release. I just tried to reproduce this problem but it builds OK for me:

PATH=/opt/llvm-20.1.5/bin:$PATH cmake --workflow appleclang-release
Executing workflow step 1 of 3: configure preset "appleclang-release"

Preset CMake variables:

  CMAKE_BUILD_TYPE="RelWithDebInfo"
  CMAKE_CXX_STANDARD="20"
  CMAKE_EXPORT_COMPILE_COMMANDS="ON"
  CMAKE_PROJECT_TOP_LEVEL_INCLUDES="./cmake/use-fetch-content.cmake"
  CMAKE_TOOLCHAIN_FILE="cmake/appleclang-toolchain.cmake"

100% tests passed, 0 tests failed out of 99

Total Test time (real) =  14.15 sec

The error on issue 153 looks like a mismatch between the used C++ run-time library and the library it was compiled with. I just noticed that the issue is with Intel Macs - so far I have only tried to run ARM Macs. I'll try with an Intel Mac, too.

The installed version is not usable:

bash-5.2$ cmake -B build -S .
CMake Error at CMakeLists.txt:17 (find_package):
  Could not find a configuration file for package "beman.execution" that
  exactly matches requested version "0.0.2".

  The following configuration files were considered but not accepted:

    /Users/clausklein/.local/lib/cmake/beman.execution/beman.execution-config.cmake, version: unknown



-- Configuring incomplete, errors occurred!
bash-5.2$

That's more concerning: that is something obviously undesirable. I haven't tried the changes, yet, with projects depending on execution (one additional motivation for meddling with the CMakeLists.txt was that recent versions of execution couldn't be used with net or task but I need some of the recent execution fixes.

I don't have a project set up which uses execution via find_package: do you have a URL for such a project or a basic CMakeLists.txt to reproduce the problem?

However, these use Apple's /usr/bin/clang++ when building rather than a recent LLVM release

I have brew installed with llvm-20.
The clang-tools must in path to be used while build my projects. The most apple tools are old!

I need cmake, clang-tidy, clang-format, clang++, ...

ClausKlein · 2025-06-01T21:13:18Z

The new workflow presets are not usable in general!

My old presets supports also package preset.

How would you install after a workflow build?
I found only non working docs!
