``` [settings] os=Linux os_build=Linux arch=x86_64 arch_build=x86_64 compiler=gcc compiler.version=9 compiler.libcxx=libstdc++11 build_type=Release [options] [conf] [build_requires] [env] ```

Steps to reproduce

with an empty conan cache (conan remove "*" -f) build boost for python using the following barebones recipe:

import os
from conans import ConanFile, tools

class BoostPython(ConanFile):
    name = "boost-python"
    version = "0.0.1"
    description = "A dummy package for building/installing boost with python"
    settings = "os", "compiler", "build_type", "arch"
    topics = ("conan")

    def requirements(self):
        self.requires("boost/1.79.0#c77cfe98fe8bc0c5814f907c54f5de0f")

    def configure(self):
        self.options["boost"].without_python = False

This issue surfaced on my CI machine after I pulled packages/recipes from conancenter on 8/6. This issue likely surfaced after 8/1, which was my last successful clean build of the above recipe.

The failure occurs for all recent boost recipe revisions. I suspect the package_info check may ignore recipe revisions - machines that have not communicated with conancenter since 8/1 are still able to run package_info without rejecting the python libraries.

Might be fixed in PR: #11998

NormanT7 commented 2 years ago

I ran into this as well. I dug into the recipe and discovered that the issue arises from the following lines (1574-1577) in the package_info() method:

if not self.options.without_python:
    pyversion = Version(self._python_version)
    libformatdata["py_major"] = pyversion.major
    libformatdata["py_minor"] = pyversion.minor

Where Version is conan.tools.scm.Version. The problem is that the major and minor attributes only recently became available (looks like version greater than Conan 1.50). In older versions (I'm using 1.48), using the major and minor attributes results in the strings "<bound method Version.major of '3.8'>" and "<bound method Version.minor of '3.8'>" respectively. Then those are used to generate the expected boost and numpy library names and of course no libraries are found with those names.

Using the latest version of Conan should fix the issue.

The recipe could also be updated to simply use conan.tools.Version in this location (and possibly others) which does have the expected behavior even on older versions of Conan. Otherwise, the required_conan_version needs to be updated. Right now it is at >=1.47 which obviously isn't correct.

@NormanT7 The recipe has been fixed last week. Any Conan version should work without any error. Please, update your local copy of Boost recipe. Also, >=1.47 is totally correct, since tools.scm.Version is no longer used.

NormanT7 commented 2 years ago

@uilianries ah, very good. I pulled boost down from Conan center early last week and it must have been updated soon after. I now have the latest revision of the recipe and it is working with the 1.48 version of Conan that I have installed. Thank you!

Thank you for your feedback!

pcbennion commented 2 years ago

Awesome! I pulled the recipe just now and it's working with my 1.49 again.

Thank you both for the help! @NormanT7 @uilianries
