[question] Why does AutotoolsToolchain not respect tools.apple:enable_bitcode?

[lagner]

What is your question?

Hi everyone.

I am building my project on iOS with bitcode setting enabled. Conan profile looks like this

[settings]
os=iOS
os.version=13.0
arch=armv8
compiler=apple-clang
compiler.libcxx=libc++
os.sdk=iphoneos
compiler.version=15
compiler.cppstd=20
build_type=Release

[conf]
tools.cmake.cmaketoolchain:generator=Ninja
tools.cmake.cmaketoolchain:user_toolchain=["build/ios-arm64/mobile-sdk/multi/cmake-toolchain-build-release"].
tools.apple:enable_bitcode=True
tools.apple:enable_arc=True

[buildenv]

The cmake dependencies work fine. However, the autotools projects do not respect the bitcode and arc settings.

Right now I can work around this with the following code in a conanfile

def generate(self):
    tc = AutotoolsToolchain(self)
    if is_apple_os(self):
        if self.conf.get('tools.apple:enable_bitcode', check_type=bool)
            tc.extra_cflags.append('-fembed-bitcode')
            tc.extra_cxxflags.append('-fembed-bitcode')

But I'm confused, I have to do this in every recipe.

How is it supposed to work in general? Is there any reason not to respect the settings in the common AutotoolsToolchain?

Have you read the CONTRIBUTING guide?
