A wrapper around pango-1.x for Swift


Here are some common errors you might encounter and how to fix them.

Old Swift toolchain or Xcode

If you get an error such as

$ ./
error: unable to invoke subcommand: /Applications/ (No such file or directory)

this probably means that your Swift toolchain is too old. Make sure the latest toolchain (Swift 3.1 at the time of this writing) is the one that is found when you run the Swift compiler, e.g.:

$ swift --version
Apple Swift version 3.1 (swiftlang-802.0.51 clang-802.0.41)
Target: x86_64-apple-macosx10.9

on macOS, or on Linux you should get something like:

$ swift --version
Swift version 3.1 (swift-3.1-RELEASE)
Target: x86_64-unknown-linux-gnu

If you get an older version, make sure that the right version of the swift compiler is found first in your PATH. On macOS, use xcode-select to select and install the latest version, e.g.:

sudo xcode-select -s /Applications/Devel/
xcode-select --install
