[package] automake/1.16.2 and libtool/2.4.6: no Linux binary

[ericLemanissier]

When trying to consume automake or libtool, automake and libtool binaries are always missing, even if https://conan.io/center/automake/1.16.2/?user=_&channel=_&revision=&os=&tab=config has a linux configuration and https://conan.io/center/libtool/2.4.6/?user=_&channel=_&revision=&os=Linux&tab=config too
Maybe the binaries of these packages need to be regenerated after m4 was added to autoconf's requirement ?

@jgsogo @danimtb Indeed the package is missing, I can reproduce the same behavior.

automake recipe ONLY uses settings.os for its package ID, no options. However, it contains autoconf/2.69 as requirement.

The last change was 10 days ago (#2038), but only generated 3 packages:

Linux: 258f6f05ca54813b3d7180161753df7f9ccf7e1d
Macos: 3c28ba69276b46fd46e9c2060ba991d725ccab43
Windows: 3e48e69237f7f2196164383ef9dedf0f93cbf249

The current Conan search outputs the same:

conan search -r conan-center "automake/1.16.2@"
Existing packages for recipe automake/1.16.2:

Existing recipe in remote 'conan-center':

The only recent change that I found was a new transitive dependency (#2103).

The behavior occurs with Conan 1.25, 1.26 and 1.27. So, for some reason, the CCI generated a different package ID that Conan client requested for Linux.

@uilianries with this change the binary hashes get back to what they were before, so this PR should solve the issue right?

[uilianries]

@ericLemanissier Indeed! I didn't read that PR yet, thanks for linking it.

[jgsogo]

Yes, adding a requirement modifies the package-ID which turns out in missing packages in the graph. Once again, we need a job running every hour/day checking for these missing packages and triggering a build once detected. It is in the backlog (codename "tapaholes").

I suggested a different approach for the PR linked.

Thanks for noticing and opening the issue 🙌

[danimtb]

@jgsogo for future reference, we have to verify this workaround is fine or should be revisited #2197

[danimtb]

This should be "fixed" or workarounded by #2197

@ericLemanissier
I think this is fixed and can be closed.
