Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.

The above exception was the direct cause of the following exception:

probably due to update in compiler.

[j-rivero]

I think that the problem here is a change in the libc++ , concretely in 19 version;

The base template for std::char_traits has been removed in LLVM 19. If you are using std::char_traits with types other than char, wchar_t, char8_t, char16_t, char32_t or a custom character type for which you specialized std::char_traits, your code will stop working. The Standard does not mandate that a base template is provided, and such a base template is bound to be incorrect for some types, which could currently cause unexpected behavior while going undetected.

Line 235 in OgreUTFString seems to be triggering the error by a template expansion over dstring that uses a uint32.

Not sure about the best patch here, I'm going to report it upstream.

[traversaro]

Thanks a lot @j-rivero and @iche033 for the follow up on this! As it is possible to see in llvm/llvm-project@aeecef0, all the removed functions were inline, so I think it is safe to just keep using clang 18 for the time being, while keeping the generated binaries compatible with newer libcxx versions. However, I wonder if before gz-rendering10 (where we are going to have an ABI bump anyhow) could it make sense to backport https://github.com/gazebosim/gz-rendering/pull/1177/files and set the CMake option USE_OGRE2_OVERLAY to OFF so we can use newer clang version across all the life of the gz-rendering10 release?

That makes sense to me yes. The only problem I had with gazebosim/gz-rendering#1177 is that the ABI checker is complaining for the OFF default option, although I'm not sure that it is correct. In the Jetty bump to 10, I would say let's backport gazebosim/gz-rendering#1177 here and enable the option from the beginning as you suggest, even if the ABI checker is true about ABI problems in default OFF we always be using the ON version here so ABI is preserve. This has the risk that we discover some runtime problem with the lack of Overlay but I think that it is a risk that can take.

In the next major (11) there will be no problem if the gazebosim/gz-rendering#1175 goes well.

[traversaro]

The only problem I had with gazebosim/gz-rendering#1177 is that the ABI checker is complaining for the OFF default option, although I'm not sure that it is correct.

I think there was a missing assignment of a CMake variable, see gazebosim/gz-rendering#1177 (comment) and gazebosim/gz-rendering#1177 (comment) .
