Right. $? is not good enough here.
so let's generate a makefile on-the-fly:
# SED_1 and SED_2 were defined above
auto.mk: $(LIST)
echo '' > $@
for file in $(LIST); do \
create_lines_for_auto.mk >> $@ \
done
Or whatever. for each item in $(LIST) auto.mk should include:
file: fi_1le
$(COMMAND)
file: fi_2le
$(COMMAND)
# the '-' means that it is not included if it does not exist.
# make will restart the evaluation after remaking a file that is
# included in the makefile
-include auto.mk
And if anybody thinks that this is complex: he's right :-(
