Bug 45998 – Either pmake or ext3 is broken. "make: no system rules (sys.mk)."

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bob Miller 2004-03-28 08:11:16 UTC]

pmake prints "make: no system rules (sys.mk)." and exits.
Investigation shows that pmake is reading /usr/share/mk/ and ignoring the first two entries, assuming that they are . and .. .  But they aren't.  The first is ., but .. is the 11th entry.

I thought . and .. had to be first, but my ext3 filesystems are full of directories where they're in the middle.  (gentoo-sources-2.4.22-r7 is
my kernel.)

I'll attach a patch for pmake that removes the assumption that . and ..
are first.

Reproducible: Always
Steps to Reproduce:
1. Use ext3 for /usr/share/mk.
2. ls -f /usr/share/mk, ensure that . and .. are not first two entries.  If
   necessary, copy files until they aren't.
3. /usr/bin/pmake

Actual Results:  
pmake printed this.
make: no system rules (sys.mk).

Expected Results:  
pmake should have made the stuff in the current directory.

Created attachment 28215 [details, diff]
patch pmake to not assume . and .. first

This patch changes pmake's directory reading loop to not assume . and .. are
the first two entries.

I guess you didn't test building with your patch, eh?
I applied a modified version, thanks...
