[bug] CMakeDeps for Autotools based package does not contain library #17193

Closed maichmueller closed 1 month ago

Describe the bug

I have generated a conanfile recipe for a 3rd-party dependency nauty which uses autotools to configure and build. My recipe is straightforward. It pulls the source archive of the lib, and delegates the work to the conan autotools abstractions:

from conan import ConanFile
from conan.tools.files import get
from conan.tools.gnu import AutotoolsToolchain, Autotools, PkgConfig

class NautyRecipe(ConanFile):
    name = "nauty"
    version = "2.8.8"
    package_type = "static-library"
    settings = "os", "compiler", "build_type", "arch"
    generators = ["CMakeDeps", "CMakeToolchain"]

    options = {
        "fPIC": [True, False],
    }

    default_options = {
        "fPIC": True,
    }

    def source(self):
        get(
            self,
            "https://users.cecs.anu.edu.au/~bdm/nauty/nauty2_8_8.tar.gz",
            strip_root=True,
        )

    def configure(self):
        if self.settings.os == "Windows":
            self.options.rm_safe("fPIC")

    def build(self):
        ac = Autotools(self)
        ac.configure()
        ac.make()

    def generate(self):
        tc = AutotoolsToolchain(self)
        tc.configure_args.append("--enable-tls")
        tc.generate()

    def package(self):
        ac = Autotools(self)
        ac.install()

    def package_info(self):
        pkg_config = PkgConfig(
            self,
            "nauty",
            pkg_config_path=f"{self.package_folder}/libdata/pkgconfig",
        )
        pkg_config.fill_cpp_info(self.cpp_info, is_system=False)
        print(self.cpp_info.libs)

This works and builds the package just fine with conan create . --build=missing (although it seems to always rebuild the package, despite having a fitting one in the cache):

Consequently, when I try to use "nauty/2.8.8" as dependency in a downstream project, I get the error:

-- CMake-Conan: find_package(Nauty) found, 'conan install' already ran
-- Conan: Target declared 'nauty::nauty'

nauty7b72780a34b5d/p/libdata/pkgconfig/nauty.pc` contains the following:

prefix=/
exec_prefix=${prefix}
libdir=${prefix}/lib
includedir=${prefix}/include

Name: nauty
Description: Programs and library for graph isomorphism
Version: 2.8.8
Libs: -L${libdir} -lnauty
Libs.private:
Cflags: -I${includedir}

What am I missing in creating a correct conan recipe? Can I not use this autotools dependency with a cmakedeps generator?

How to reproduce it

  1. Take the above conanfile.py
  2. run conan create . on it.
  3. require nauty/2.8.8 in a consuming cmake-based package and state find_package(nauty REQUIRED) within the CMakeLists.txt

Hi @maichmueller

Thanks for your detailed report.

Indeed, the pkg_config.fill_cpp_info() is executing (seen with -vv):

nauty/2.8.8: Full command: pkg-config --print-provides nauty --print-errors
nauty/2.8.8: PkgConfig fill cpp_info for nauty
nauty/2.8.8: Full command: pkg-config --libs-only-l nauty --print-errors
nauty/2.8.8: Full command: pkg-config --libs-only-L nauty --print-errors
nauty/2.8.8: Full command: pkg-config --libs-only-other nauty --print-errors
nauty/2.8.8: Full command: pkg-config --cflags-only-other nauty --print-errors
nauty/2.8.8: Full command: pkg-config --cflags-only-I nauty --print-errors

And the internal libdirs seems to be empty:

{'root': {'includedirs': ['/include'], 'srcdirs': None, 'libdirs': [], 'resdirs': None, 'bindirs': ['bin'], 'builddirs': None, 'frameworkdirs': None, 'system_libs': [], 'frameworks': None, 'libs': ['nauty'], 'defines': [], 'cflags': [], 'cxxflags': [], 'sharedlinkflags': [], 'exelinkflags': [], 'objects': None, 'sysroot': None, 'requires': None, 'properties': None, 'exe': None, 'type': None, 'location': None, 'link_location': None}}

Because the retrieval of libdirs is returning empty:

nauty/2.8.8: PkgConfig fill cpp_info for nauty
nauty/2.8.8: Full command: pkg-config --libs-only-l nauty --print-errors
nauty/2.8.8: -lnauty

nauty/2.8.8: Full command: pkg-config --libs-only-L nauty --print-errors
nauty/2.8.8:

The culprit seems to be the prefix = /. Changing it in the generated .pc file to:

prefix=/
exec_prefix=${prefix}
libdir=lib
includedir=include

Makes things work. I think the generated .pc file seems broken, as it is pointing to some absolute /lib and /include folders that do not exist. Do you know how to change in the autotools files so these .pc files are generated with relative paths instead?

If not, most like it is not worth the effort, as a very simple package_info() with self.cpp_info.libs = ["nauty"] would work.

Hi @memsharded , thanks so much for your quick support! Appreciate it.

You are right. The package-config seems to be the culprit. I thought it looked odd before but ignored it. My knowledge of pkg-config and auto tools is pretty non-existent, to be honest. I adapted it to your advice as self.cpp_info.libs = ["nauty"], and this works for me. It's interesting that Conan is able to make this work on its own. Fantastic job!

Closing this as resolved.

The real question is who knows autotools 😂

Yes, the idea of abstracting the contents of a package in package_info() was there from the begining of Conan. Nowadays we are collaborating in the CPS standardization effort (you can see our recent talks in CppCon), that tries to come up with a better and standard representation of packages.

Thanks very much for the feedback! Don't hesitate to open new tickets for any further question or issue.
