Instances

Eq Options Source #
Methods (==) :: Options -> Options -> Bool # (/=) :: Options -> Options -> Bool #
Show Options Source #
Methods showsPrec :: Int -> Options -> ShowS # show :: Options -> String # showList :: [Options] -> ShowS #
Default Options Source #
Methods def :: Options #

defaultOptions :: Options Source #

Default pkg-config options.

This function is an alias for def.

pkgConfig :: Options -> String -> Action (BuildFlags -> BuildFlags) Source #

Call pkg-config with options and a package name and return a BuildFlags modification function.

The pkg-config executable must be installed on the build host.

fromConfig :: Options -> (String -> Action (Maybe String)) -> Action (BuildFlags -> BuildFlags) Source #

Given an initial Options record and a configuration variable lookup function, call pkg-config based on configuration variable settings and return a BuildFlags modification function.

The following configuration variables are recognised:

PkgConfig.packages: List of package names for which build flags should be queried
PkgConfig.options.searchPath: Space-separated list of file paths, corresponds to the searchPath option
PkgConfig.options.static: true or false, corresponds to the static option
