What were you trying to do?
Building a makefile.
What's wrong:
The current man page for make says that $< should expand to the
full list of prereqs for a given target. Currently it seems to
expand to the null string.
What should have happened:
Either the documentation should have not mislead me, or the full
list of prereqs should have been substituted for $<...
I suspect the documentation is simply out-of-date.
Please describe any relevant documentation references:
/usr/man/man1/make.1
Sample:
Create a dummy file foo and a makefile.
unix% cp /dev/null foo
unix% cat << 'EOF' > Makefile
bar: foo
echo $<
'EOF'
unix% make
echo
unix% ......
I would have expected it to be "echo foo".
