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) and found it was in an excellent condition.

I would also

• Backport this to 11.x
• Build boost*=1.78 with this
• Build a new abseil-cpp with this
• Start the migration for both of them

Could you provide some details, why you consider to remove explicit std settings? As so we will use default behavior of clang-driver, which might get different for different versions. I agree that this way override of it via option gets more strict, but I might miss here something more interesting.

This is based on @isuruf suggestion in #17 (comment)

[xhochy]

@isuruf Would you have time to look at this? I would be happy to bring this forward.

@katietz, the issue with an explicit -std=c++14 is that it circumvents most build systems C++ setting. For some packages that need C++17, this forces them to use C++14. With clang 11, C++14 is the default, so this doesn't change anything for clang 11. However, it provides an easier way to use C++17 if a package needs it.

@katietz, any thought on this?

Since I didn't hear from @katietz, going to assume this is okay.

thanks, got clear to me why. Sorry that I was a bit off, but had to do the 3.10 built out on Anaconda's side... I am fine with the change

Thanks
