[question] Managing multiple C++ packages within the same git repository

[KingKiller100]

• [x] I've read the CONTRIBUTING guide.

  Version

  Conan Version: 1.54.0

  Summary

  I have two projects using conanfile.py to manage their dependencies. Both are editable packages. Package B is dependent on Package A. Each time I try to install Package B, ($ conan install ...), it fails. I checked the command's logs and it looks like it is falling during or after (I can't tell) trying to retrieve Package A. I am confused about what I am doing wrong here.

Could you please advise? If any more information is need (such as seeing the contents of the conanfile.py of each package) please let me know.

Directory Structure

Hi @KingKiller100

I suspect that there could be something in the package_info() of the PackageA that is affecting the propagation, probably something related to the conf. Yes, it would be great to see your conanfile.py, that could give some further ideas.

Also, just a quick suggestion for the future, regarding to package name PackageA: try to use package names in lowercase only, because ConanCenter has been forcing that for years, and Conan 2.0 will force lowercase packages (there will be a temporary workaround, but the recommendation is lowercase)

[KingKiller100]

Good evening,

Thank you so much for answering back. Thank you for the information about package names, I will make sure to enforce all packages are lowercase in future to avoid any trouble.

Update

Whilst I was waiting for your response, I figured out the cause of the issue was a name clashing with something Conan uses and I was typing the object to be a list. the object was called "dependencies". This is why the error occurred.

I have gotten past that issue and now suffering a new one that looks similar but I'm struggling to find the source of the issue within the scripts. Now my issue is with the MSBuildDeps generator.

Could you aid me please? Is there a list of reserved names by conan that I can reference to prevent issues like this happening again?

Here are the contents of my scripts.

Whilst I was waiting for your response, I figured out the cause of the issue was a name clashing with something Conan uses and I was typing the object to be a list. the object was called "dependencies". This is why the error occurred.

Good catch. Yes, there are some rules in the docs in https://docs.conan.io/en/latest/reference/conanfile.html to avoid this type of conflicts, please use your own attributes and methods as _mymethod() and _myattribute, as the public ones and _conan_xxx are reserved for Conan.

Thanks for sharing your conanfiles. I have checked it, and indeed it seems a bug in the MSBuildDeps generator when the dependencies are in editable mode. Related comment in this issue: https://github.com/conan-io/conan/issues/12310#issuecomment-1300512984

Let's try to fix it for next release.

I'd also like to share some general feedback that might help to start being prepared for 2.0 (that is getting very close):

• Do not mix the legacy tools, like from conans import ConanFile, tools, MSBuild with the new ones. You should also import and use from conan.tools.microsoft import MSBuild, not the other one.
• The scm as attribute has been dropped in 2.0, you might want to check https://docs.conan.io/en/latest/reference/conanfile/tools/scm/git.html#example-implementing-the-scm-feature to see about the 2.0-ready alternative
• Calling conan application from recipes is undefined behavior, it is very discouraged, and it will be explicitly forbidden in 2.0. The command = f"conan inspect {path} --raw=version" can probably be replaced by some other alternative. If you want a mechanism to define the versions in the meta-project, you could have a data file to define the versions, and that data file can be read (that is what set_version() is for), and it can also be used in the export() to capture the dependencies information.
• The in_local_cache also dissapears in 2.0. The idea is that full usage of def layout() allows to correctly define the cpp_info for both editable and package in the cache, without using this variable at all. What you are doing in self.cpp_info.libdirs = [ f"temp/MsBuild/Output/{self.settings.build_type}" ] is more or less what should go to layout() to self.cpp.build.libdirs = ....
• Settings and options are "read-only". Their values shouldn't be changed in recipes, like self.settings.build_type = f"{self.settings.build_type}_v141" The recommendation is that such information should come defined from the profile. There are mechanisms that can help for that, for example, profiles can be jinja templates that contain some logic to define values. There is also a new "profile plugin" in 2.0 that can inject extra logic.
• The self.copy() can be replaced by ``copy(self, ...) new 2.0-ready method

There are some guidelines in https://docs.conan.io/en/latest/conan_v2.html, it would be great to keep an eye on them, we have done a ton of effort to backport things to 1.X, so the upgrade to 2.0 could be much smoother.

Trying a fix in https://github.com/conan-io/conan/pull/12529, for next 1.55

Wonderful. I will await v1.55.x for the fix
