Hi,
I've implemented build system that uses advanced auto-dependency
generation as described by Paul Smith
All works fine except one thing : if user changes compilation flags
(e.g. modifies CFLAGS that are set in Makefile) or modifies list of
libraries to link with (e.g. via LDFLAGS) make obvoiusly can't detect
this. To fix that one may add Makefile itself as a prerequisite to all
object files and library/executable targets but that seems an overkill
any change in Makefile will cause full rebuild of all targets in that
Makefile.
Is there more intelligent solution to this problem ?
I was thinking about creating checksum from options passed to compiler
and store them in deps files similar to file dependency information but
how could I tell make to mark target out of date if some checksum
doesn't match previously computed ?
Thanks
Chris
