is duplicated by:

  • SR-883 Support conditional dependencies
  • SR-3233 Demands -Xlinker invocation even though modulemap already contains it
  • SR-3488 C/C++ packages can't be built for Android
  • SR-3838 Swift Package Manager can't specify C-language mode (-std option) per module
  • SR-4194 Lookup pkg-config files in system packages
  • SR-5851 swift build can't change -target
  • SR-8497 Make cross-test-target dependencies possible
  • SR-3484 Swift PM fails to build package with C++ and ObjC++ targets

relates to:

  • SR-3660 Add support for custom build configuration

Issue Description:

The package manager has no way to provide specific settings, such as compiler flags, for building the targets in a package. Some settings are critical for production code, such as the "deployment target" (the minimum OS version that the built code will run on). We need to provide a way to set at least the most important settings which users will need control over.

Comment by Amr Aboelela (JIRA)

In UserToolchain.swift:

self.extraSwiftCFlags = [

        "-target", destination.target,

        "-sdk", destination.sdk.asString

    \] + destination.extraSwiftCFlags

And in build_ubuntu_cross_compilation_toolchain:

swift build --destination /tmp/cross-toolchain/ubuntu-xenial-destination.json

...

cat > "$cross_tc_basename/ubuntu-xenial-destination.json" <<EOF

{

"version": 1,

"sdk": "$(pwd)/$cross_tc_basename/$linux_sdk_name",

"toolchain-bin-dir": "$(pwd)/$cross_tc_basename/$xc_tc_name/usr/bin",

"target": "linux-unknown-x86_64",

...

}

So the answer of our question seems to create a destination.json file, fill it with the deployment target then run:

$ swift build --destination destination.json
