Machine: Sun Ultra1

System: SunOS 4.1.3
Machine: Sun SPARCstation 330

System: Linux 1.2.3
Architecture: i486
Makefiles involving suffix targets do not work properly.
The following error is produced with multiple build directories:

cat ../../../src/util/profile/profile.hin prof_err.h > profile.h
cat: cannot open prof_err.h
*** Error code 2
make: Warning: Command failed for target `profile.h' (on host lindy)
Current working directory /home2/matt/krb/krb5-1.0pl1/solaris2.5/util/profile

If this is fixed by creating prof_err.h by hand (i.e. running
awk with the explicit filenames), then 'make' fails to create any of the
.o files for the util/profile directory. Presumably if the .o files are
all compiled by hand, other errors will show up in other directories.


Follow the instructions in section 3.3.2 of the Installation Guide.

Changes of the following sorts should be made to the appropriate
Makefiles:

(1) remove '.SUFFIXES:' lines

(2) targets like .et.h: should be rewritten as %.h:
$< should be rewritten as $*.et

(3) targets like .c.o: should be rewritten as %.o:

I build Kerberos for about 5 architectures using separate object trees,
and I've never had this problem.

I sent in a bug report yesterday (7/25), krb5-build/450. Ken Hornstein
(kenh@cmf.nrl.navy.mil) suggested that I might not be using GNU make, and
of course it turns out I wasn't. I still wonder why VPATH is used instead of
%, but I'm sure there's a good reason.

Sorry for the false alarm,

- Matt

user error; should use gmake for offset builds on SunOS, etc.

VPATH is used in preference to pattern rules to allow the Makefiles to
be used at all on platforms that don't support "%" type pattern rules,
without using VPATH either. It so happens that using VPATH causes
fewer side effects on the compatibility of the Makefiles with
minimalistic makes.
