Distribution.Simple.Configure

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.

getInstalledPackages :: Verbosity -> Compiler -> PackageDB -> ProgramConfiguration -> IO (Maybe (PackageIndex InstalledPackageInfo))

Source

configDependency :: Verbosity -> PackageIndex InstalledPackageInfo -> Dependency -> IO PackageIdentifier

Source

Test for a package dependency and record the version we have installed.

configCompiler :: Maybe CompilerFlavor -> Maybe FilePath -> Maybe FilePath -> ProgramConfiguration -> Verbosity -> IO (Compiler, ProgramConfiguration)

configCompilerAux :: ConfigFlags -> IO (Compiler, ProgramConfiguration)

ccLdOptionsBuildInfo :: [String] -> [String] -> BuildInfo

Source

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))
