Hello,
How can I achieve the following?
Suppose, I have a dependency that extracts compilable information
from a data source, and another rule that retrieves the data source
e.g. from the web:
info.h: info.txt
sed -f info.sed info.txt > info.h
info.txt:
wget http://blabla/info.txt
Now of course I want info.h to be made if info.txt exists and
is newer.
But it is also possible that info.txt is not available but info.h
is still there. In this case I want it to be done and not try to
retrieve info.txt (so I might actually leave out the second rule).
How can this be done?
Thanks and kind regards,
Thomas Wolff
