Add mold 2.0.0

[fschoenm]

Specify library name and version: mold/2.0.0

Essentially a version bump. mold 2.0.0 has been relicensed from AGPL to MIT (see Release Notes for mold 2.0.0), which is why I moved the old all folder to 1.x.x and created a new all folder that essentially only changed the license attribute. I hope that's the correct approach.

Can anybody advise how to solve the CI issue? Seems like some package is missing. In the #conan Slack channel I was told that somebody from the team has to run a build for missing packages?

[mgehre-amd]

I'd love to have mold 2.0 in conan. The error you are getting seems to be in mold/1.7.1, so I wonder whether you PR changes anything about that is being build?

[fschoenm]

@mgehre-amd IMO I didn't change anything there. On the slack channel somebody told me I have to wait for the team to help with that but I don't know what to do with this issue or how to get in contact.

The onetbb issue is a recurrent one (#19229 (comment)) and @uilianries is looking into it, it seems.

The #18848 PR should help with any Conan v1 issues in the mold v1 recipe, once it gets merged.

[uilianries]

@fschoenm Thank you for your contribution, good catch with the license change! Please, let's keep it simpler:

• Keep everything in the same recipe, there is no big change that justify such duplication.
• You can change the license according the version, it's something already used in CCI: https://github.com/conan-io/conan-center-index/blob/master/recipes/jfalcou-eve/all/conanfile.py#L41

[fschoenm]

@uilianries Thanks for the pointer, I didn't know that is possible. Maybe could be added to the contribution documentation (or maybe I just didn't see it) :)

[uilianries]

@fschoenm changing a recipe is something rare, but indeed it deserves be documented. I'll open a PR soon.

[uilianries]

NICE!

[fschoenm]

Is there a problem with the CI system? It says something about an unexpected error.

[fschoenm]

@uilianries Unfortunately, it still didn't work.

I saw that there's a onetbb package depending on hwloc/2.9.Z on conancenter:

fbd41063c30b49345892a94c8747c6efed28b489
  info
    settings
      arch: x86_64
      build_type: Release
      compiler: gcc
      compiler.cppstd: 17
      compiler.libcxx: libstdc++11
      compiler.version: 11
      os: Linux
    options
      shared: True
      tbbbind: True
      tbbmalloc: True
      tbbproxy: True
    requires
      hwloc/2.9.Z

But the build requires onetbb depending on hwloc/2.9.3:

onetbb/2021.3.0: WARN: Can't find a 'onetbb/2021.3.0' package binary 'd7a9f73b4f7a501a35ebea3234d4801bf5740350' for the configuration:

I'm not really sure what it means. I think it has something to do with full_mode vs minor_mode but I'm unclear how these are determined.

[uilianries]

There was problem related to the OneTBB and its supported package IDs, but I created a PR fixing it: #20786

I just started the PR again. Let's if it works now.

[fschoenm]

@uilianries Sorry but that's no fix at all. It doesn't change the fact, that the onetbb package required for mold needs hwloc/2.9.3 instead of hwloc/2.9.Z.

Here is a possible explanation: conan-io/conan#15040 (comment)

[SpaceIm]

#20897 should avoid missing package id for this case. It may lead to other issues related to missing packages in downstream recipes.

[SpaceIm]

You have to wait a little bit after merge of a PR (not just 3 min), before new packages can be available.

Looking good, asking @franramirez688 for an extra review.
