mpv: add flag for swift on darwin
While we currently don't have a pure swift build on macOS it's possible to build mpv using the swift compiler from CLT. eg. self: super: let CommandLineTools = "/Library/Developer/CommandLineTools"; in { swift = super.stdenv.mkDerivation { name = "swift-CommandLineTools-0.0.0"; phases = [ "installPhase" "fixupPhase" ]; propagatedBuildInputs = [ self.darwin.DarwinTools ]; installPhase = '' mkdir -p $out/bin $out/lib ln -s ${CommandLineTools}/usr/bin/swift $out/bin ln -s ${CommandLineTools}/usr/lib/swift $out/lib ln -s ${CommandLineTools}/SDKs $out ''; setupHook = builtins.toFile "hook" '' addCommandLineTools() { echo >&2 echo "WARNING: this is impure and unreliable, make sure the CommandLineTools are installed!" >&2 echo " $ xcode-select --install" >&2 echo >&2 [ -d ${CommandLineTools} ] export NIX_LDFLAGS+=" -L@out@/lib/swift/macosx" export SWIFT=swift export SWIFT_LIB_DYNAMIC=@out@/lib/swift/macosx export MACOS_SDK_VERSION=$(sw_vers -productVersion | awk -F. '{print $1 "." $2}') export MACOS_SDK=@out@/SDKs/MacOSX$MACOS_SDK_VERSION.sdk } prePhases+=" addCommandLineTools" ''; __impureHostDeps = [ CommandLineTools ]; }; mpv = super.mpv.override { swiftSupport = true; }; }
