Details:
Have test makefile:
.SILENT:
.PHONY: depended_remake_always
all : depended_remake_always main
depended_remake_always :
if [ \( ! -e ./depended_real_file \) -o \( ./depended -nt
./depended_real_file \) ]; then \
touch depended_real_file; \
echo depended_real_file remade; \
fi
depended_real_file: depended_remake_always
#
main: depended_real_file
echo "about to do main"
touch main
in command line
touch depended
make -f test.mak main
doesn't proceed rule main while depended_remake_always made. It happens
because timestamps of main and depended_real_file compared on wrong stage:
namely BEFORE depended_real_file rule FULLY executes.
As workaround
touch depended
make -f test.mak all
works as it should
