To do this you'll need to be tricky, because you want to know what the state of the directory is before any rules are invoked; you can find that out like this: FILES := $(wildcard info.h info.txt) Now you can check which ones existed. So for example, if you only wanted to run the wget if neither existed, you could do something like this (there are obviously many ways to do it): info.txt: ifndef FILES wget -N http://blabla/info.txt endif or whatever. -- ------------------------------------------------------------------------------- Paul D.
