GNU make 3.54 is behaving strangely on our NCR Tower32/600 with
operating sys release 02.01 (System V.2). The problem has to do with
archive members, GNU make thinks they are always out of date and
remakes them every time. This could just be a behaviour difference
between GNU make an the standard one -- if that's so then would
someone please tell me how I should maintain libraries with GNU make!
The following script illustrates the problem:
% ls -C
Makefile ajat.c date.c misc.c
% cat Makefile
CC=cc
CFLAGS=-O -I../../hdrs_10
LIB=testlib.a
LOBJ= $(LIB)(ajat.o) $(LIB)(date.o) $(LIB)(misc.o)
$(LIB): $(LOBJ)
$(LIB)(ajat.o): ajat.c
$(LIB)(date.o): date.c
$(LIB)(misc.o): misc.c
% make # This is the system 'make'
cc -c -O -I../../hdrs_10 ajat.c
ar rv testlib.a ajat.o
ar: creating testlib.a
a - ajat.o
rm -f ajat.o
cc -c -O -I../../hdrs_10 date.c
ar rv testlib.a date.o
a - date.o
rm -f date.o
cc -c -O -I../../hdrs_10 misc.c
ar rv testlib.a misc.o
a - misc.o
rm -f misc.o
% make
`testlib.a' is up to date.
% rm test* *.o
% gmake # GNU Make 3.54
cc -O -I../../hdrs_10 -c ajat.c -o ajat.o
ar rv testlib.a ajat.o
ar: creating testlib.a
a - ajat.o
cc -O -I../../hdrs_10 -c date.c -o date.o
ar rv testlib.a date.o
a - date.o
cc -O -I../../hdrs_10 -c misc.c -o misc.o
ar rv testlib.a misc.o
a - misc.o
rm ajat.o date.o misc.o
Now the fun begins... we try gmake again.
% gmake
cc -O -I../../hdrs_10 -c ajat.c -o ajat.o
ar rv testlib.a ajat.o
r - ajat.o
cc -O -I../../hdrs_10 -c date.c -o date.o
ar rv testlib.a date.o
r - date.o
cc -O -I../../hdrs_10 -c misc.c -o misc.o
ar rv testlib.a misc.o
r - misc.o
rm ajat.o date.o misc.o
... and repeats this every time.
% ls -C
Makefile ajat.c date.c misc.c testlib.a
% make # Normal 'make'
`testlib.a' is up to date.
In the following sequence, GNU make doesn't seem to be
able to locate the archive members...
% gmake -t
touch ajat.o
touch testlib.a(ajat.o)
gmake: touch: Member `ajat.o' does not exist in `testlib.a'
touch date.o
touch testlib.a(date.o)
gmake: touch: Member `date.o' does not exist in `testlib.a'
touch misc.o
touch testlib.a(misc.o)
gmake: touch: Member `misc.o' does not exist in `testlib.a'
rm ajat.o date.o misc.o
% gmake -d
