Both of these set of files have absolute paths. Regarding the shell wrappers (e.g. $GHC_HOME/bin/{ghc,ghc- pkg,ghci,runghc,runhaskell}), we could simply use a slightly different scheme. For instance, an alternative for the ghc wrapper: {{{ #!/bin/sh GHC_HOME=$( cd $(dirname $0)/.. ; pwd ) exedir="${GHC_HOME}/lib/ghc-7.8.2/bin" exeprog="ghc-stage2" executablename="$exedir/$exeprog" datadir="${GHC_HOME}/lib" bindir="${GHC_HOME}/bin" topdir="${GHC_HOME}" executablename="$exedir/ghc" exec "$executablename" -B"$topdir" ${1+"$@"} }}} The critical piece is {{{ GHC_HOME=$( cd $(dirname $0)/.. ; pwd ) }}} since it needs to work for all supported platforms. Other than that, it is pretty straight-forward. I see that there is support for a {{{RelocatableBuild}}} variable in config.mk, but it is turned on only on Windows: {{{ # On Windows we normally want to make a relocatable bindist, to we # ignore flags like libdir ifeq "$(Windows_Host)" "YES" RelocatableBuild = YES else RelocatableBuild = NO endif }}} So it seems that we have two different layouts: one for Windows and one for everything else: {{{ exec_prefix = ${prefix} bindir = ${exec_prefix}/bin datadir = ${datarootdir} libdir = ${exec_prefix}/lib includedir = ${prefix}/include mandir = ${datarootdir}/man docdir = ${datarootdir}/doc/${PACKAGE_TARNAME} $(eval $(call set_default,docdir,$${datarootdir}/doc/ghc)) htmldir = ${docdir} dvidir = ${docdir} pdfdir = ${docdir} psdir = ${docdir} $(eval $(call set_default,htmldir,$${docdir})) $(eval $(call set_default,dvidir,$${docdir})) $(eval $(call set_default,pdfdir,$${docdir})) $(eval $(call set_default,psdir,$${docdir})) ifeq "$(RelocatableBuild)" "YES" # Hack: our directory layouts tend to be different on Windows, so # hack around configure's bogus assumptions here. datarootdir = $(prefix) datadir = $(prefix)/lib libdir = $(prefix)/lib docdir = $(prefix)/doc htmldir = $(docdir) dvidir = $(docdir) pdfdir = $(docdir) psdir = $(docdir) ghclibdir = $(libdir) ghcdocdir = $(datarootdir)/doc else # Unix: override libdir and datadir to put ghc-specific stuff in # a subdirectory with the version number included. # # datadir is set to libdir here as GHC needs package.conf and unlit # to be in the same place (and things like ghc-pkg need to agree on # where package.conf is, so we just set it globally). # ghclibdir = $(libdir)/$(CrossCompilePrefix)ghc-$(ProjectVersion) ghcdocdir = $(datarootdir)/doc/ghc endif ghclibexecdir = $(ghclibdir) topdir = $(ghclibdir) ghcheaderdir = $(ghclibdir)/include }}} Why two layouts? I also see that the non-windows layout is accounting for cross compilation, which is doesn't seem supported in the Windows layout. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/284#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
