Description

This deals with the configure phase. It provides the configure action which is given the package description and configure flags. It then tries to: configure the compiler; resolves any conditionals in the package description; resolve the package dependencies; check if all the extensions used by this package are supported by the compiler; check that all the build tools are available (including version checks if appropriate); checks for any required pkg-config packages (updating the BuildInfo with the results)

Then based on all this it saves the info in the LocalBuildInfo and writes it out to the dist/setup-config file. It also displays various details to the user, the amount of information displayed depending on the verbosity level.

Documentation
configure :: (Either GenericPackageDescription PackageDescription, HookedBuildInfo) -> ConfigFlags -> IO LocalBuildInfoSource
Perform the "./setup configure" action. Returns the .setup-config file.
writePersistBuildConfig :: FilePath -> LocalBuildInfo -> IO ()Source
After running configure, output the LocalBuildInfo to the localBuildInfoFile.
getPersistBuildConfig :: FilePath -> IO LocalBuildInfoSource
Read the localBuildInfoFile. Error if it doesn't exist. Also fail if the file containing LocalBuildInfo is older than the .cabal file, indicating that a re-configure is required.
checkPersistBuildConfig :: FilePath -> FilePath -> IO ()Source
Check that localBuildInfoFile is up-to-date with respect to the .cabal file.
maybeGetPersistBuildConfig :: FilePath -> IO (Maybe LocalBuildInfo)Source
Try to read the localBuildInfoFile.
localBuildInfoFile :: FilePath -> FilePathSource
dist/setup-config
getInstalledPackages :: Verbosity -> Compiler -> PackageDB -> ProgramConfiguration -> IO (Maybe (PackageIndex InstalledPackageInfo))Source
configDependency :: Verbosity -> PackageIndex InstalledPackageInfo -> Dependency -> IO PackageIdentifierSource
Test for a package dependency and record the version we have installed.
configCompiler :: Maybe CompilerFlavor -> Maybe FilePath -> Maybe FilePath -> ProgramConfiguration -> Verbosity -> IO (Compiler, ProgramConfiguration)Source
configCompilerAux :: ConfigFlags -> IO (Compiler, ProgramConfiguration)Source
ccLdOptionsBuildInfo :: [String] -> [String] -> BuildInfoSource

Makes a BuildInfo from C compiler and linker flags.

This can be used with the output from configuration programs like pkg-config and similar package-specific programs like mysql-config, freealut-config etc. For example: 

 ccflags <- rawSystemProgramStdoutConf verbosity prog conf ["--cflags"]
 ldflags <- rawSystemProgramStdoutConf verbosity prog conf ["--libs"]
 return (ccldOptionsBuildInfo (words ccflags) (words ldflags))

checkForeignDeps :: PackageDescription -> LocalBuildInfo -> Verbosity -> IO ()Source
