They would then be using the real executables directly, not through wrapper scripts. This works because GHCs produced by hadrian on those systems are relocatable. This means that you can copy the @bin@ and @lib@ dirs anywhere and GHC will keep working, as long as both directories sit next to each other. (This is achieved by having GHC look up its $libdir relatively to where the GHC executable resides.) It is however still possible (and simple) to install a GHC distribution that uses wrapper scripts. From the unpacked archive, you can simply do: ./configure --prefix= [... other configure options ...] make install In order to support @bin@ and @lib@ directories that don't sit next to each other, the install script: * installs programs into @LIBDIR/ghc-VERSION/bin@ * installs libraries into @LIBDIR/ghc-VERSION/lib@ * installs the wrappers scripts into @BINDIR@ directory -} bindistRules :: Rules () bindistRules = do root <- buildRootRules phony "install" $ do need ["binary-dist-dir"] version <- setting ProjectVersion targetPlatform <- setting TargetPlatformFull let ghcVersionPretty = "ghc-" ++ version ++ "-" ++ targetPlatform bindistFilesDir = root -/- "bindist" -/- ghcVersionPretty prefixErr = "You must specify a path with --prefix when using the" ++ " 'install' rule" installPrefix <- fromMaybe (error prefixErr) <$> cmdPrefix runBuilder (Configure bindistFilesDir) ["--prefix="++installPrefix] [] [] runBuilder (Make bindistFilesDir) ["install"] [] [] phony "binary-dist-dir" $ do -- We 'need' all binaries and libraries all_pkgs <- stagePackages Stage1 (lib_targets, bin_targets) <- partitionEithers <$> mapM pkgTarget all_pkgs cross <- flag CrossCompiling iserv_targets <- if cross then pure [] else iservBins need (lib_targets ++ (map (\(_, p) -> p) (bin_targets ++ iserv_targets))) version <- setting ProjectVersion targetPlatform <- setting TargetPlatformFull distDir <- Context.distDir Stage1 rtsDir <- pkgIdentifier rts let ghcBuildDir = root -/- stageString Stage1 bindistFilesDir = root -/- "bindist" -/- ghcVersionPretty ghcVersionPretty = "ghc-" ++ version ++ "-" ++ targetPlatform rtsIncludeDir = ghcBuildDir -/- "lib" -/- distDir -/- rtsDir -/- "include" -- We create the bindist directory at /bindist/ghc-X.Y.Z-platform/ -- and populate it with Stage2 build results createDirectory bindistFilesDir createDirectory (bindistFilesDir -/- "bin") createDirectory (bindistFilesDir -/- "lib") -- Also create wrappers with version suffixes (#20074) forM_ (bin_targets ++ iserv_targets) $ \(pkg, prog_path) -> do let orig_filename = takeFileName prog_path (name, ext) = splitExtensions orig_filename suffix = if useGhcPrefix pkg then "ghc-" ++ version else version version_prog = name ++ "-" ++ suffix ++ ext -- Install the actual executable with a version suffix install_path = bindistFilesDir -/- "bin" -/- version_prog -- The wrapper doesn't have a version unversioned_install_path = (bindistFilesDir -/- "bin" -/- orig_filename) -- 1.
