Swift Package Manager questions

Edward_Connell · 2016-10-16T23:53:44.000Z

Hi, I've written a Swift (with some C) framework the builds and runs
cleanly in Xcode 8.
A critical feature of my project is for my framework to run on MacOS, iOS,
and Linux.
I am trying to figure out how to build using the SPM so I can run on Ubuntu.
I'm not so happy with the project structure now, but at least I think I am
almost there.

I've hit a sticking point that I can't seem to figure out. The SPM sets the
target SDK to 10.10 by default.
Features in Swift 3.0 that I am using require at least 10.11. When I type:

*swift build -Xcc -I/usr/local/include -Xswiftc -j4 -Xlinker
-L/usr/local/lib -Xlinker -lpng -Xlinker -ljpeg*

The build bombs with:

"... error: 'init(fileURLWithPath:relativeTo:)' is only available on OS X
10.11 or newer"

How do I set the correct OS version??

I looked at the Xcode settings and tried to pass them through, but there
seems to be an argument parsing error by SPM.
I am currently trying:

*swift build -Xcc -I/usr/local/include -Xswiftc -j4 -Xswiftc -sdk
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk
-Xswiftc -target x86_64-apple-macosx10.12 -Xlinker -L/usr/local/lib
-Xlinker -lpng -Xlinker -ljpeg*

And I get:

error: unknown command:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk

So it seems it thinks the parameter is a command.

*How do you set the sdk and target versions through swift build to fix this
problem?*

Thanks, Ed

MacBook Pro (Retina, 13-inch, Early 2015)

Sierra 10.12 (16A323)

Hi,

Currently in Swift 3 release of SwiftPM, you cannot override this setting.
A proper solution to this problem is yet to be built in SwiftPM however in
the mean time this patch was landed to allow overrides by passing custom
args: Reorder swiftc args to allow user override by keith · Pull Request #715 · apple/swift-package-manager · GitHub
It is available in a recent trunk snapshot from swift.org

Also, while passing custom arguments to swift build, escape each argument
with the prefix eg:
*`-Xswiftc -target x86_64-apple-macosx10.12` **should be:** `**-Xswiftc
-target **-Xswiftc **x86_64-apple-macosx10.12`*

Thanks Ankit,
Should I be able to pick up that change with Xcode 8.1 beta 3 (latest)? Oct
10th.

Hi Ed,

No, the package manager in the Xcode 8.1 beta only has minimal bug fixes.

You can, however, get this by grabbing a snapshot toolchain from http://swift.org/download\.
