Re: [Crash-utility] [RFC] makedumpfile, crash: LZO compression support
----- Original Message -----
This could involve configure.c, but conceivably it could all be done
within the
Makefile itself. For example, by entering something like "make
compress=lzo2",
and then adding this to the Makefile:
ifneq ($(compress),)
ifeq ($(compress), lzo2)
LZOFLAG=-DLZO
LZOLIB=-llzo2
endif
endif
And then the diskdump.c compile line could use ${LZOFLAG}, and the
gdb_merge stanza could include ${LZOLIB}.
On the other hand, the capability of dynamically adding an optional
library could be a useful feature in general -- not only for LZO
compression support, but for other things in the future.
I'm thinking that we could allow the user create an "extralibs" file
in the top-level directory, and then build_configure() in configure.c
could read it and dynamically create the LDFLAGS= line in the Makefile.
Currently LDFLAGS can only be modified manually, but the -static example
hasn't worked for a long time, and should be removed.
