Start with version information of `0:0:0' for each libtool library. # | # | 2. Update the version information only immediately before a public # | release of your software. More frequent updates are unnecessary, # | and only guarantee that the current interface number gets larger # | faster. # | # | 3. If the library source code has changed at all since the last # | update, then increment REVISION (`C:R:A' becomes `C:r+1:A'). # # [So it seems like we should always update the middle 'R' field # for any release.] # # | 4. If any interfaces have been added, removed, or changed since the # | last update, increment CURRENT, and set REVISION to 0. # | # | 5. If any interfaces have been added since the last public release, # | then increment AGE. # # [These two rules seem to mean that if any change is made to the # generator, we should increment C and A, and set R to 0, so: # C+1:0:A+1.] # # | 6. If any interfaces have been removed since the last public release, # | then set AGE to 0. # # [Our ABI guarantee means we won't remove interfaces except in # very exceptional circumstances.] # # The maximum proc number (see guestfs_protocol.x:guestfs_procedure) is # a mostly accurate stand-in for C & A in rules 5 & 6, so we use that. It # is always incremented when we add a new appliance interface, and easy to # calculate. # # The middle number is hard to increment-and-reset as described in rules # 4 & 5, so for the moment it is always set to 0. # # Note that this scheme means the real library version will always be # 'libguestfs.so.0.$(MAX_PROC_NR).0'. libguestfs_la_LDFLAGS = -version-info $(MAX_PROC_NR):0:$(MAX_PROC_NR) libguestfs_la_SOURCES = \ guestfs.c \ guestfs.h \ guestfs_protocol.c \ guestfs_protocol.h \ guestfs-actions.h \ guestfs-actions.c \ guestfs-bindtests.c \ gettext.h libguestfs_la_CFLAGS = -Wall -DGUESTFS_DEFAULT_PATH='"$(libdir)/guestfs"' if HAVE_RPCGEN guestfs_protocol.c: guestfs_protocol.x rm -f $@-t $@-t2 $(RPCGEN) -c -o $@-t $< sed 's,\.\./\.\./src/,,' < $@-t > $@-t2 rm $@-t mv $@-t2 $@ guestfs_protocol.h: guestfs_protocol.x rm -f $@-t $(RPCGEN) -h -o $@-t $< mv $@-t $@ endif
