Conan recipe

[nicolasWDC]

Could it be possible to put eigenpy on conan center ?
It would simplify our build process.

Hello @nicolasWDC,

We doesn't use Conan internally so we will not maintain a recipe.
If you want to add and maintain an eigenpy recipe on Conan center you're more than welcome. We will be happy to help you in the process.
Also, we will soon merge #612 that will modernize our CMake and can help with Conan compatibility.

Last time I tried (3 years ago) I wrote the follow recipe:

from conan import ConanFile
from conan.tools.cmake import CMake, CMakeToolchain, cmake_layout
from conan.tools.scm import Git


class EigenPyConan(ConanFile):
    name = "eigenpy"
    version = "3.1.1"
    settings = "os", "compiler", "build_type", "arch"
    generators = "CMakeDeps"

    license = "BSD-2-Clause"
    author = "stack-of-stacks"
    url = "https://github.com/stack-of-tasks/eigenpy"
    description = "Efficient bindings between Numpy and Eigen using Boost.Python"

    # Binary configuration
    settings = "os", "compiler", "build_type", "arch"
    options = {"shared": [True, False], "fPIC": [True, False]}
    default_options = {"shared": False, "fPIC": True}

    def config_options(self):
        if self.settings.os == "Windows":
            del self.options.fPIC

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

    def layout(self):
        cmake_layout(self)
        self.cpp.build.includedirs = ["include"]

    def generate(self):
        tc = CMakeToolchain(self)
        tc.generate()

    def requirements(self):
        self.requires("boost/[>1.70.0]")
        self.requires("eigen/[>3.0.5]")

    def source(self):
        git = Git(self)
        git.clone(
            url="https://github.com/stack-of-tasks/eigenpy",
            target=".",
            args=[f"-bv{self.version}", "--recursive"],
        )

    def build(self):
        cmake = CMake(self)
        cmake.configure()
        cmake.build()

    def package(self):
        cmake = CMake(self)
        cmake.install()

    def package_info(self):
        self.cpp_info.libs = ["eigenpy"]
        # self.cpp_info.requires = ["boost::headers", "boost::python"]
