Hello,
I found a little problem with an example in section 4.14 in the GNU make documentation:
This edition of the GNU Make Manual, last updated 08 July 2002, documents GNU make
Version 3.80.
If you have targets in subdirectories, the sed call will not work properly because gcc
will issue a lilne like
b.o: sub/b.c /usr/include/stdio.h /usr/include/features.h ...
$* will be set to sub/b, so the sed substitution command won't find anything to
substitute. I append my solution. Of course, it will fail if filenames contain colons.
Sincerely,
Jochen
