Autotools packages are ignoring host profile and building for the build profile #16493

Open ViliusSutkus89 opened 2 weeks ago

ViliusSutkus89 commented 2 weeks ago

Description

Hello, I'm trying to build some software for Android, but I've noticed that all of the autoconf packages are ignoring my host profile and just build for my build machine. This becomes apparent only when I try to link against the freshly built binary.

Here's a GitHub actions run illustrating the problem: https://github.com/ViliusSutkus89/conan-center-index/actions/runs/9534760342

CMake and Meson packages seem to be building fine, so it's just the Autotools

Package and Environment Details

Conan profile

Profile host: [settings] arch=armv8 build_type=Release compiler=clang compiler.cppstd=20 compiler.libcxx=c++_static compiler.version=17 os=Android os.api_level=23 [conf] tools.android:ndk_path=/usr/local/lib/android/sdk/ndk/26.3.11579264

Profile build: [settings] arch=x86_64 build_type=Release compiler=clang compiler.cppstd=17 compiler.libcxx=libstdc++11 compiler.version=15 os=Linux

Steps to reproduce

conan create recipes/libiconv/all/conanfile.py --version=1.17 --profile:host armv8

I have a workaround in def generate(self): which sets the correct ENV vars for the toolchain, but it's not really fun applying that workaround to each affected package.

    def generate(self):
        tc = AutotoolsToolchain(self)
        # ...
        env = tc.environment()
        if cross_building(self) and self.settings.os == "Android":
            # NDK binary paths need to be supplied as posixpath, not os path, even on windows
            # This means no backslashes, because scripts in NDK don't like backslashes
            android_ndk_home = self.conf.get("tools.android:ndk_path").replace("\\", "/")

            }[self.settings.get_safe("arch")]
            api_level = self.settings.os.get_safe("api_level")

            build_machine = "{}-x86_64".format({"Linux": "linux", "Macos": "darwin","Windows": "windows"}[str(self.settings_build.os)])

            toolchain = posixpath.join(android_ndk_home, "toolchains", "llvm", "prebuilt", build_machine, "bin")

                executable_suffix = ".exe"
            else:
                executable_suffix = ""

            env.define("AR", posixpath.join(toolchain, "llvm-ar" + executable_suffix))
            env.define("AS", posixpath.join(toolchain, "llvm-as" + executable_suffix))

Hi @ViliusSutkus89 thanks a lot for taking the time to report the issue, we appreciate it.

We'll take a look into this as soon as we can, you might be onto something :)

I've ran into more autotools packages that I want to use, so instead of patching every single one of them, I've added the toolchain to my host profile:

{% set android_home = os.getenv("ANDROID_HOME") %}
{% set ndk_version = "26.3.11579264" %}
{% set api_level = "21" %}

os.api_level={{api_level}}

STRIP={{android_home}}/ndk/{{ndk_version}}/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-strip

CC and CXX are different for each abi:

I still count this as a workaround, not a proper solution, because I would have to add it to host profiles of every downstream user of my Android libraries.

tools.android:ndk_path is not a silver bullet.

There is indeed some magic in CMakeToolchain & MesonToolchain when tools.android:ndk_path is set:

Except of that there is no magic, so your profile must provide these information. It's not really an issue for conancenter, but for conan client. The confusion comes from the fact that this micro-management of Android NDK details has been implemented in some conan helpers and not in others, so there is now an expectation from users that it should work out of the box irrespective of underlying build system.

Fully agree with the part that this is a conan client, not a conan center issue. Sorry about misfiling. Haven't looked much into conan client code yet, but I assume that it would be the correct place for a proper solution, not these profile workarounds.

moving this to conan client -!
