shake-language-c

shake-language-c is a cross-platform build system based on the Shake Haskell library. The focus is on cross-compilation of C, C++ and Objective C source code to various target platforms. Currently supported target platforms are iOS, Android NDK, Google Portable Native Client, MacOS X, Linux and Windows (MinGW). Supported host platforms are MacOS X, Linux and Windows.

Examples

Here’s an iOS example that compiles all .cpp files in the src directory. The resulting static library libexample.a can then be used e.g. from an XCode project.

import Control.Applicative
import Control.Arrow
import Development.Shake
import Development.Shake.FilePath
import Development.Shake.Language.C
import qualified Development.Shake.Language.C.Target.OSX as OSX

main :: IO ()
main = shakeArgs shakeOptions { shakeFiles = "build/" } $ do
  let target = OSX.target OSX.iPhoneOS (Arm Armv7s)
      toolChain = OSX.toolChain
                    <$> OSX.getSDKRoot
                    <*> (maximum <$> OSX.getPlatformVersions (targetPlatform target))
                    <*> pure target

  lib <- staticLibrary toolChain
          ("build" </> toBuildPrefix target </> "libexample.a")
          (return $ 
               append compilerFlags [(Just Cpp, ["-std=c++11"])]
           >>> append compilerFlags [(Nothing, ["-O3"])]
           >>> append userIncludes ["include"] )
          (getDirectoryFiles "" ["src//*.cpp"])

  want [lib]

A more complex build script is used by the Methcla sound engine library. It defines Shake rules for building the library on various platforms and also exports functions for transparently including the library into other build systems. The build script makes extensive use of Shake configuration files.
