[sword-devel] SWORD_VERSION

[Troy A. Griffitts]

Hey Jaak,

I can see how this is useful, though I believe the standard way to 
handle this with any package is to define what you need with, e.g.,

pkg-config --atleast-version=1.6.2 sword

You can define what you want, like INCLUDES_WLC_VERSIFICATION, or 
whatever you need to have special code for, based on the SWORD library 
version.  Unless you change the whole world of package versioning 
formats, I'm not sure it helps much for just us to add a new format.  If 
you still want to use the comparable version number in your code, you 
could currently do something like

SWORD_VERSION := $(shell pkg-config --modversion sword | awk -F. 
'{printf("%0.2x%0.2x%0.2x\n",$$1,$$2,$$3)}')
CFLAGS += -DSWORD_VERSION=0x$(SWORD_VERSION)

which would also work for you with any package.

Hope this helps.  If you still think we should define a special hex 
version number in future releases, please let me know.

Troy
