The layout is as follows: # # libperl: # # This is a slotted (SLOT=[0-9]*) ebuild, meaning we should be able to have a # few versions that are not binary compadible installed. # # How we get libperl.so multi-versioned, is by adding to the link command: # # -Wl,-soname -Wl,libperl.so.`echo $(LIBPERL) | cut -d. -f3` # # This gives us: # # $(LIBPERL): $& perl$(OBJ_EXT) $(obj) $(LIBPERLEXPORT) # $(LD) -o $@ $(SHRPLDFLAGS) perl$(OBJ_EXT) $(obj) \ # -Wl,-soname -Wl,libperl.so.`echo $(LIBPERL) | cut -d. -f3` # # We then configure perl with LIBPERL set to: # # LIBPERL="libperl.so.${SLOT}.`echo ${PV} | cut -d. -f1,2`" # # Or with the variables defined in this ebuild: # # LIBPERL="libperl.so.${PERLSLOT}.${SHORT_PV}" # # The result is that our 'soname' is 'libperl.so.${PERLSLOT}' (at the time of # writing this for perl-5.8.0, 'libperl.so.1'), causing all apps that is linked # to libperl to link to 'libperl.so.${PERLSLOT}'. # # If a new perl version, perl-z.y.z comes out that have a libperl not binary # compatible with the previous version, we just keep the previous libperl # installed, and all apps linked to it will still be able to use: # # libperl.so.${PERLSLOT}' # # while the new ones will link to: # # libperl.so.$((PERLSLOT+1))' # # perl: # # Not much to this one. It compiles with a static libperl.a, and are unslotted # (meaning SLOT=0). We thus always have the latest *stable* perl version # installed, with corrisponding version of libperl. The perl ebuild will of # course DEPEND on libperl. # # Martin Schlemmer <azarah@gentoo.org> (28 Dec 2002).
