That's not really true. His patch just causes the make clean to delete the .depend files, and you can immediately do a make depend/make all. If you do that following a make cleandir, you end up with object files scattered through your sources, because the make cleandir wiped away your obj directories. I'm not saying that with some forethought, you couldn't use make cleandir, because I use it myself. I'm saying that making things more complicated is causing people to make errors, which are being posted here, and those errors could be painlessly eliminated via the patch. What's the gain in not doing the clean of the .depend files? Just rebuilding them. Seems like a fair trade to me. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 9120 Edmonston Ct #302 | Greenbelt, MD 20770 | I run Journey2 and n3lxx, both FreeBSD (301) 220-2114 | version 2.2 current -- and great FUN! ----------------------------+-----------------------------------------------
