Is there an equivalent or anything else which can help me to write this
rule avoiding this warning message?
I think here you can use something like:
.xcf.bmp:
$(GIMP) -i -b '(xcf-bmp "$<" "$@")' -b '(gimp-quit 0)'
Note the order is PREREQ-EXT before TARGET-EXT, which is opposite
of the pattern rule order. Probably Automake manual (and its readers)
could benefit from changing the mysterious:
We do not discuss pattern rules here because they are not
portable, but they can be convenient in packages that assume GNU
`make'.
to something like:
Although pattern rules are not portable, they can be convenient
in packages that assume GNU `make'. In the common case where
the pattern rule is used to match the stem of a filename, you
can use the old fashioned suffix rule (pxref here) instead.
For example:
# pattern rule, not portable
%.bmp : %.xcf
$(GIMP) -i -b '(xcf-bmp "$<" "$@")' -b '(gimp-quit 0)'
# old fashioned suffix rule, portable
.xcf.bmp:
$(GIMP) -i -b '(xcf-bmp "$<" "$@")' -b '(gimp-quit 0)'
Hey, maybe Automake hackers can riff off this thread in time for
the next release... (or, "Would you like me to submit a patch?").
