Distribution.Simple.Configure
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.

configure :: (GenericPackageDescription, HookedBuildInfo) -> ConfigFlags -> IO LocalBuildInfo Source
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 LocalBuildInfo Source
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.
checkPersistBuildConfigOutdated :: FilePath -> FilePath -> IO Bool Source
Check that localBuildInfoFile is up-to-date with respect to the .cabal file.
tryGetPersistBuildConfig :: FilePath -> IO (Either ConfigStateFileError LocalBuildInfo) Source
Try to read the localBuildInfoFile.
maybeGetPersistBuildConfig :: FilePath -> IO (Maybe LocalBuildInfo) Source
Try to read the localBuildInfoFile.
localBuildInfoFile :: FilePath -> FilePath Source
dist/setup-config
getInstalledPackages :: Verbosity -> Compiler -> PackageDBStack -> ProgramConfiguration -> IO PackageIndex Source
getPackageDBContents :: Verbosity -> Compiler -> PackageDB -> ProgramConfiguration -> IO PackageIndex Source
Like getInstalledPackages, but for a single package DB.
configCompiler :: Maybe CompilerFlavor -> Maybe FilePath -> Maybe FilePath -> ProgramConfiguration -> Verbosity -> IO (Compiler, ProgramConfiguration) Source
Deprecated: configCompiler is deprecated. Use configCompilerEx instead.
configCompilerAux :: ConfigFlags -> IO (Compiler, ProgramConfiguration) Source
Deprecated: configCompilerAux is deprecated. Use configCompilerAuxEx instead.
configCompilerEx :: Maybe CompilerFlavor -> Maybe FilePath -> Maybe FilePath -> ProgramConfiguration -> Verbosity -> IO (Compiler, Platform, ProgramConfiguration) Source
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))
checkForeignDeps :: PackageDescription -> LocalBuildInfo -> Verbosity -> IO () Source
interpretPackageDbFlags :: Bool -> [Maybe PackageDB] -> PackageDBStack Source
The user interface specifies the package dbs to use with a combination of
--global, --user and --package-db=global|user|clear|$file.
This function combines the global/user flag and interprets the package-db
flag into a single package db stack.
