I have a medium-sized, moderately complex Makefile that I use to maintain my current modelling project. This Makefile seems to generate the correct behavior on a variety of machines, including: IRIS 3000, VAX VMS, ETA-10 UNIX (Sys V), Sun 4 I get the following broken behavior on the Personal IRIS: 1. I update a header file 2. I type 'make model' It 'makes' correctly 4. I type 'make model' again It repeats the previous make, even though everything is up-to-date. 5. I repeat step 4 several times. Usually by the 3rd or fourth time, it finally understands that everything is up-to-date and it does not have to make anything anymore. I have checked the times on the files, and they are correct. I have tried 'make -t' and it doesn't seem to notice --- it still re-makes the target several times more than it needs to.... The only thing that I am doing which is unusual is that I have turned off most of the rules and replaced them with my own, since I am using a fortran pre-processor that make does not know about by default. Any ideas out there? -- John D. McCalpin - mccalpin@masig1.ocean.fsu.edu - mccalpin@nu.cs.fsu.edu mccalpin@delocn.udel.edu

Not much to go on but:
Does this still happen if you don't override the rules (maybe create
your own ~/bin/f77 to do preprocessing and then call /usr/bin/f77).
Are you editting locally but doing the make over NFS? unsynchronized
clocks sometimes force make to run several minutes after the dependency
was editted.
