[bug] conan info --dry-build missing fails

[Sil3ntStorm]

Environment details

• Operating System+version: Ubuntu Focal
• Compiler+version: clang16
• Conan version: 1.60.2
• Python version: 3.10.9

Steps to reproduce

Using the following list of requirements:

    def requirements(self):
        self.requires('abseil/20230125.3')
        self.requires('c-ares/1.19.1')
        self.requires('grpc/1.54.3')
        self.requires('ms-gsl/4.0.0')
        self.requires('nlohmann_json/3.11.2')
        self.requires('openssl/[>=1.1 <4]')
        self.requires('opus/1.3.1')
        self.requires('quazip/1.4')
        self.requires('boost/1.82.0')
        self.requires('qt/6.5.2')
        self.requires('zlib/1.2.13')

    def build_requirements(self):
        self.tool_requires('protobuf/3.21.12')
        self.tool_requires('grpc/1.54.3')
        self.tool_requires('qt/6.5.2') # For Qt tools

Run conan info --update --dry-build missing .

If you skip the --dry-build missing it runs.

Logs

ERROR: Conflict in nss/3.89:
    'nss/3.89' requires 'sqlite3/3.41.2' while 'nss/3.89' requires 'sqlite3/3.42.0'.

Trying to do a conan install --build missing will fail in the same way

Hi @Sil3ntStorm

Thanks for your report.

I have tried to reproduce in Windows and Linux and so far I haven't been able to reproduce it. Maybe it was something pending in ConanCenter that was waiting to be merged, and now it is fixed? Could you please check it again? (Make sure your cache is empty first, just in case)

[Sil3ntStorm]

Windows Build works, it is just the Linux one that fails, I am guessing due to the additional (build) requirements.

Then run
conan remove -f "*/*" to kill the cache
conan install --update --build missing --json conan-build-info.json .

Which will check and download all the recipes, and then fail on the nss requirement for sqlite/3.41.2.

I think this is due to nss having a build requirement of sqlite (for whatever reason), whereas qt has a requirement of 3.42.0. Both are build_requires, which throws it off.

[Sil3ntStorm]

Curiously even if you first just build nss/3.89 first (which works), it will still complain about the sqlite requirement issue.

[memsharded]

Thanks for the details.
I think you are right, it is possible that some of those options will bring conditional requirements that are not the default, I'll try later with those options.

Have you tried to add an extra tool_requires to 'sqlite3/3.42.0' to see if it can resolve the conflict? Have you tried some other mechanism to solve the conflict?

I think it is also worth checking in ConanCenter, maybe it is just something that can be quickly fixed there by bumping some dependencies.

[memsharded]

Trying conan-io/conan-center-index#19579

[Sil3ntStorm]

I have already tried with both a newer version of nss (which still has the old sqlite3 dependency), as well as modifying the nss recipe to require the same sqlite3 version as Qt6. However unfortunately without much success.

In the end I have unexplained build failures in the icu package, but that is probably a side effect of messing around. No more time to mess around with this today.

[memsharded]

We haven't had time to check this again, hopefully it is not an issue anymore, not even sure if it was a Conan issue or a recipe issue.

I am closing this as inactive at the moment, but don't hesitate to re-open or create a new ticket if still failing or any further question. Best if reported against Conan 2.0, which was released 1 year ago already, it will be more prioritized.
