conan-deploy-lipo

Conan custom command to deploy macOS or iOS universal binaries. This wraps around Conan's full_deploy deployer and then runs lipo to produce universal binaries.

Installing

The custom command files need to be installed to ~/.conan2/extensions/commands

conan config install ./config

Usage

cd ./xcode
conan deploy-lipo . -pr x86_64 -pr armv8 -b missing
conan build .
file ./build/Release/example

This assumes profiles named x86_64 and armv8 with corresponding architectures. Universal binaries can only have one binary per architecture but each can have different settings, e.g. minimum deployment OS:

x86_64

[settings]
arch=x86_64
build_type=Release
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos
os.version=10.13

armv8

[settings]
arch=armv8
build_type=Release
compiler=apple-clang
compiler.cppstd=gnu17
compiler.libcxx=libc++
compiler.version=14
os=Macos
os.version=11.0

Limitations

This does not integrate with Conan's generators and is mainly intended for a standalone Xcode project that does not use a conanfile.
