How can I tell in my cabal file that wlan.hs should be built first than settings.hs than demo3.hs?

You need some changes like this (as a Darcs patch): adddir ./HNM move ./settings.hs ./HNM/Settings.hs move ./wlan.hs ./HNM/WLAN.hs hunk ./hnm.cabal 3 - -Description: Happy Network Manager - -License: BSD +Synopsis: Happy Network Manager +Category: Network, System +homepage: http://sert.homedns.org/hs/hnm/ +License: BSD3 hunk ./hnm.cabal 9 - -Maintainer: cetin@sertcom.de +Maintainer: hunk ./hnm.cabal 13 +data-files: settings.conf + hunk ./hnm.cabal 17 - -ghc-options: -O3 -fglasgow-exts +other-modules: HNM.WLAN, HNM.Settings +ghc-options: -O2 -fglasgow-exts Note that -O3 is counterintuitively no better than -O2, and may be worse. You should probably change the -fglasgow-exts to individual per-file {-# LANGUAGE #-} pragmas. And you don't declare all your dependencies, for example I see Gtk2Hs imports, but no declarations in build-depends:. To solve your problem, you need to put the module names in other-modules:, but your modules are at wrong names. If a module's name is HNM.Settings, then it needs to be at Settings.hs. - -- gwern -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAklRGQcACgkQvpDo5Pfl1oLDHgCfcRswCMsUUPZLknvUrENM/MmD U7gAoIBq0CXXU6XHKn0L4kGi45zENNJ3 =txxi -----END PGP SIGNATURE-----

You need to follow the standard file name convention for modules. The module HNM.WLAN needs to be in the file HNM/WLAN.hs rather than wlan.hs. Similarly you will need to rename settings.hs to HNM/Settings.hs. That way cabal and ghc will be able to find the files. In the .cabal file you do not need these fields: Extra-Source-Files: wlan.hs, settings.hs HS-Source-Dirs: . Instead you should use: other-modules: HNM.WLAN, HNM.Settings Looking at: ghc-options: -fglasgow-exts -O3 --make you do not need '--make'. Using 'cabal check' or 'sdist' will have other suggestions for better portability and recommended practise. Duncan
