cling: changes needed on MacOS to avoid G__Core.cxx generation failures complaining about time_point
On one installation of MacOS with Sonoma 14.6.1 and XCode 15.4 and clang-1500.3.9.4 (not sure about the xcode command line tool version), the generation of G__Core.cxx failed until we applied the change in this commit.
On another installation of MacOS with the same version numbers the change was not needed but the change did not hurt either.
In module 'std' imported from input_line_1:1:

Is this done upstream? I'm not feeling comfortable changing the copied modulemaps too much, we have to move to a more dynamic scheme to not break on changes by Apple, and every local modification makes this harder. So far, we "only" added a surrounding std module and removed one module that broke because of that. This one looks like we either set up something wrongly, or there is a problem in vanilla libc++ already...

That hasn't landed yet and even if it did today, it's still multiple versions of SDK down the road. So why are we seeing problems now that nobody else has? And where do we see them at all, because our CI is green?

Simply because our use of C++ modules is on the bleeding edge.
That doesn't really answer any of my two questions: There are other parties than us using the libc++ modulemap, notably Apple. Why don't they see this problem? And what is special about the two installations alluded to in the commit message, when it's working in the CI?

I am not sure how to answer them. Apple Swift uses that modulemap for something to do C++ interop with. I do not know the details but Swift-C++ is probably not the go-to choice for swift developers most of the time. I am not sure what's the answer to your second question. That's for @pcanal to answer but the answer does not really matters. Before it did not work after this patch works for his setup.
It does matter a lot because I'm totally not happy that we are starting to patch the modulemap that we copied from Apple's distribution of libc++. If it's the only possibility, then we can do it but I'm not able to assess that without knowing why it doesn't work in Philippe's while many other installations, including our CI nodes, are completely fine.

I am not happy either. However, I do not see what we are after here? He, just like any other random user, installed something from Apple and thing broke. The options here are basically two: a) tell the user he is wrong and not fix it which is silly; b) fix it. The only place we could fix it is the modulemap as that's the only place we have write access to :)
@stognini's installation and mine looked identical but his failed while mine worked (without the patch). If you can tell "what" else to check on the unusual system, please let us know. I.e. @stognini can run any small command to probe his system.
@stognini @pcanal here are some commands that should get us a decent overview of the compiler + SDK setup:

ninja: build stopped: subcommand failed.
So I reinstalled the command line tools (see for example https://root-forum.cern.ch/t/root-on-macos-15-xcode-16/61716/9). and rebuild. With the rebuild worked with the master as-is (commit 55cd181c3d), so the patch is not needed on my machine at this time. The new environment info is:

It's still not clear to me why this change is needed in one particular configuration, ie what is different to all other developers building on macOS, our CI, ... Also I would to point out once more that patching our modulemap for macOS is not at all sustainable. In the past, we never had problems because we just took whatever Apple shipped with libc++. We started having a copy to revert an upstream change and have a single big std module, to avoid having to fix other stuff and for claimed performance reasons. An automatic solution was discussed back then (ie take what Apple ships and modify it during cmake configuration time), but I don't know where we are with this. @dpiparo @devajithvs @vgvassilev
There has been some progress in https://github.com/llvm/llvm-project/issues/86193, however, as far as I can tell it is not sufficient...

This is the upstream part, which is important. However, we also discussed that we want an automatic solution downstream, ie not maintain a copy of the modulemap but instead create it dynamically from the file found in the SDK. This would solve all recent problems because it's again on Apple / libc++ to provide a valid modulemap.

I'd like to avoid that as a long term solution because that's a libc++ problem... There were steps in the right direction, however, the use-case coverage we have seems to exceed theirs...

I'm confused, I thought this was the agreed short-term solution that at least doesn't require patching every time there is a new SDK. What is your proposal to reduce problems until it is fixed upstream, released by Apple, and all older versions are EOL?

I did look into that very briefly. It won't be a direct copy-paste from the SDK as we have some patches on top of it like: https://github.com/root-project/root/commit/8045591a17125b49c1007787c586868dea764479, but should be doable in CMake.

(and https://github.com/root-project/root/pull/18235 for the comment above)
After a bit more digging, I was able to make a reproducer with AppleClang. I think it is a problem in Apple’s current libc++ module-map, not a ROOT problem.
#include <filesystem>
int main() {
std::filesystem::file_time_type::clock::now();
return 0;
}
clang++ -std=c++20 -fmodules -fcxx-modules reproducer.cpp

https://github.com/root-project/root/pull/18515 - fixes this without changing modulemaps
Is the pr deliberately avoiding a fix is the modulemap?
Yes, but just an alternative fix. Fixing module-map as per this also looks ok to me, since this is already an issue we have with clang on Apple.

In that case we can re-export std_private_chrono_time_point from time_point in the modulemap on osx...
