Dependency Analysis

Please note that this analysis is highly experimental. The aim here is to make maintenance easier by inspecting the package's dependencies. Importantly this analysis does not support optional dependencies, please double check those before making changes. If you do not want hinting of this kind ever please add bot: inspection: false to your conda-forge.yml. If you encounter issues with this feature please ping the bot team conda-forge/bot.

Analysis by source code inspection shows a discrepancy between it and the the package's stated requirements in the meta.yaml.

Packages found in the meta.yaml but not found by source code inspection:

• libcxx
• boost

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.

@stuarteberg Apparently std::shared_mutex (a C++11 functionality) is not available in OSX earlier that 10.12, which causes some builds to fail (although not for arm64). I don't think it's a big deal to require only newer versions of that OS, since version 10.11 is quite old already. (I'm preparing some new new importat functionality of graph-tool that will require std::shared_mutex even more extensively.)

However, I don't know how we can restrict the build to MacOS 10.12 or newer. Do you?

Hi! This is the friendly conda-forge automerge bot!

I considered the following status checks when analyzing this PR:

• linter: passed
• azure: passed

Thus the PR was passing and merged! Have a great day!

The build error actually links to the conda-forge docs. Cool, I didn't realize they could do that!

The docs claim that the clang error doesn't apply in our case. Clang THINKS that symbol isn't available because our build uses MACOSX_DEPLOYMENT_TARGET=10.9, and clang just assumes we must be using the system's own libcxx. (BTW, as you can see there, the osx_arm64 builds use a newer target, which explains why they passed.)

In actual fact, we're using a newer libcxx provided by conda-forge which was nonetheless built to be compatible with old macOS versions. So the docs claim we can just add the following flag to skip the checks and trust that our libcxx has everything we need:

CXXFLAGS="${CXXFLAGS} -D_LIBCPP_DISABLE_AVAILABILITY"

...so I'm trying that now.

I don't know how we can restrict the build to MacOS 10.12 or newer. Do you?

If the above change doesn't work, then the conda-forge docs explain how to build with newer SDKs..

I suppose there must be some risk that the above change won't work. Otherwise, wouldn't the conda-forge folks have added it to CXXFLAGS by default? ¯\ (ツ)/¯
