jfalcou-eve/v2022.03.0

Latest version of EVE now requires clang 13 and g++ 11 on Linux

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

If it is only required for certain versions, it should be conditioned to those versions.

[jfalcou]

Is there something I should do to fix those issues?

[jgsogo]

it looks like some missing c++ standard feature, right?

Either apple-clang 13.0 doesn't support it, or you need to activate that standard in the build-system files

[jfalcou]

Well, the previous recipe worked before so that's rather strange.
Same for MSVC, I thought the previous recipe deactivated them cause we just don't support them.

[jfalcou]

or should I remove the msvc apple-clang line entirely?

[jgsogo]

The latest PR to this recipe is 5 months old, by that time apple-clang 13 was not used here. So this is the first time this recipe tries this compiler. As this is a newer version for apple-clang I would recommend investigating the failure instead of ignoring it. Apple-clang 13 is the default in the macos world now.

[jfalcou]

Yes maybe.
The thing is, I don't have an apple machine to do such a test but it looks like apple-clang just doesn't have the correct libc++ for C++20. So I don't see what I could do but not support apple-clang till they update their compiler stack.

For me it's the same than not working with sub-par MSVC. The library just doesn't support it.

[jgsogo]

You are the author of the library, so you are the best one to declare if the library is supposed to work or not with those compilers. Probably the best way to go is to skip here that compiler-version and then modify the sources to support it and, with a new release of the library, enable those compiler-versions here again.

[jfalcou]

OK. So I just remove the apple-clang entry then ?

[jgsogo]

But still I don´t understand the purpose of this PR. The new compiler-version requirements apply to v2022.03.0 version, which is not added.

You should use something a bit more complex (pseudocode):

def validate(self):
   if self.version in ['cci.20210823', 'v2021.10.0']:
      # Check for supported compilers (the ones already in the recipe)
      
      # Even if apple-clang should be supported (regarding C++ standard), it is isn't
      if self.settings.compiler == ´apple-clang'  and self.settings.compiler.version >= 13:
         raise ConanInvalidConfiguration("Not supported")
         
   if self.version in ['v2022.03.0']:
      # New checks for supported compilers (the ones in this PR), which are more restritive

You don't want people that was using an existing version with some compiler to start getting an error just because new versions doesn´t support that compiler.

[jfalcou]

the thing is that it never supported apple-clang. The original recipe was not written by me and I try to make it uptodate.
Will give a try to your solution.

Hey guys, how can I help for having this PR landed?

[jfalcou]

We need to make it so it clearly states it doesn't compile on Apple Clang. I didn't have time to patch it.
Be my guest if you want to give it a try, I can help with details.

EDIT: I also missed the folders rules. Will add them

[jgsogo]

You have added version v2022.03.0 in the file config.yml, but you haven't added the corresponding entry to conandata.yml. This is why you get the error:

ERROR: jfalcou-eve/v2022.03.0: Error in source() method, line 62
	tools.get(**self.conan_data["sources"][self.version], strip_root=True,
	KeyError: 'sources'

[jgsogo]

	if  tools.scm.Version(self.version) >= "2022.03.0":
	AttributeError: module 'conan.tools' has no attribute 'scm'

It should work, but it doesn't. It is a bug in current Conan releases, but it is not going to be backported (at least not just because of this bug) as the workaround is pretty straightforward (from conan.tools.scm import Version).

Sorry for the inconvenience.

Please do not force push 🙏 GitHub forces us to restart the review which is not fun!

[prince-chrismc]

The conan v2 API need a higher version (this is not the right one but just better)

Suggested change

	required_conan_version = ">=1.33.0"
	required_conan_version = ">=1.43.0"
