----------------------------------------------------------------------------- -- | -- Module : Distribution.Make -- Copyright : Martin Sjögren 2004 -- -- Maintainer : cabal-devel@haskell.org -- Portability : portable -- -- This is an alternative build system that delegates everything to the @make@ -- program. All the commands just end up calling @make@ with appropriate -- arguments. The intention was to allow preexisting packages that used -- makefiles to be wrapped into Cabal packages. In practice essentially all -- such packages were converted over to the \"Simple\" build system instead. -- Consequently this module is not used much and it certainly only sees cursory -- maintenance and no testing. Perhaps at some point we should stop pretending -- that it works. -- -- Uses the parsed command-line from "Distribution.Simple.Setup" in order to build -- Haskell tools using a backend build system based on make. Obviously we -- assume that there is a configure script, and that after the ConfigCmd has -- been run, there is a Makefile. Further assumptions: -- -- [ConfigCmd] We assume the configure script accepts -- @--with-hc@, -- @--with-hc-pkg@, -- @--prefix@, -- @--bindir@, -- @--libdir@, -- @--libexecdir@, -- @--datadir@. -- -- [BuildCmd] We assume that the default Makefile target will build everything. -- -- [InstallCmd] We assume there is an @install@ target. Note that we assume that -- this does *not* register the package! -- -- [CopyCmd] We assume there is a @copy@ target, and a variable @$(destdir)@. -- The @copy@ target should probably just invoke @make install@ -- recursively (e.g. @$(MAKE) install prefix=$(destdir)\/$(prefix) -- bindir=$(destdir)\/$(bindir)@. The reason we can\'t invoke @make -- install@ directly here is that we don\'t know the value of @$(prefix)@. -- -- [SDistCmd] We assume there is a @dist@ target. -- -- [RegisterCmd] We assume there is a @register@ target and a variable @$(user)@. -- -- [UnregisterCmd] We assume there is an @unregister@ target. -- -- [HaddockCmd] We assume there is a @docs@ or @doc@ target. -- copy : -- $(MAKE) install prefix=$(destdir)/$(prefix) \ -- bindir=$(destdir)/$(bindir) \ {- All rights reserved.
