[question] How to access `self.options` of a parent library package from its test package?

[PauloCarvalhoRJ]

Greetings,

So, I have a test package (test_package sub-directory in the source repository) inside a package named zlib/1.2.11. In zlib's own recipe, I have:

    options = {"shared": [True, False],
               "fPIC": [True, False],
               "minizip": [True, False],
               "os_version": ["linux", "windows", "other"],
               }

I need to access zlib's self.options.minizip value in test package's recipe:

cmake.definitions["WITH_MINIZIP"] = self.options["zlib"].minizip

The code above works with Conan 1, but in Conan 2 I get this error:

ERROR: zlib/1.2.11 (test package): Error in build() method, line 20
        cmake.definitions["WITH_MINIZIP"] = self.options["zlib"].minizip
        ConanException: option 'minizip' doesn't exist
Possible options are []

Then the question is: How can one now (Conan 2) access options values of library packages in their respective test packages?

Thanks in advance,

PC

Hi @PauloCarvalhoRJ thanks a lot for your question.

In Conan 2 (And new enough Conan 1 versions!) you'll be looking for the self.dependencies (docs here) accessor

With this, you can query your tested package options like so in a test_package: self.dependencies[self.tested_reference_str].options.minizip (Or just replace the self.tested_reference_str for the library name for any other dependency if needed in general recipes)

I hope this helps :)

Hello,

Thank you. The new API is more readable in Conan 2. The error shifted to the cmake.dependencies side, but I'll start another question for the issue.

best,
