I've successfully managed to get a simulated TOPS20 environment going with
networking. Now there's a new strange hitch: the behavior of make. Would
someone please look at this and tell me what I'm doing wrong?
For a simple Makefile, it works fine if I just type "make", but if I type
"make <target>", I get the commands sent to the command line, but no
responses. The display then stalls at the eighth source file. Strangely,
if I scroll up in the xterm, it gets dragged back down as if more stuff is
being printed.
Just typing "make", I get this:
@make
cc -c buffer.c -o buffer.rel
PANDA TOPS-20 Command processor 7.1(4453)-4
@cc -c buffer.c -o buffer.rel
KCC: BUFFER
<DAVE.FROTZ>BUFFER.PRE.3
<DAVE.FROTZ>BUFFER.FAI.3
FAIL: BUFFER
@
@POP
... and so on until this:
@POP
cc -o dfrotz.exe buffer.rel err.rel fastme.rel files.rel getopt.rel
... more .rel files
LINK: Loading
@
@POP
@
and we're done. dfrotz.exe is in the current directory and it works.
Here's the strange behavior I can't explain:
@make dumb
cc -c buffer.c -o buffer.rel
?Unrecognized command - Does not match switch or keyword - "dumb"
cc -c err.c -o err.rel
cc -c fastme.c -o fastme.rel
cc -c files.c -o files.rel
cc -c getopt.c -o getopt.rel
cc -c hotkey.c -o hotkey.rel
cc -c input.c -o input.rel
cc -c main.c -o main.rel
The process stalls at this point, jerking back the terminal to the bottom
if I scroll up. Hitting ^C once or repeatedly doesn't seem to do
anything. Logging into the from a different terminal, I can see that no
.rel files were generated from this operation.
Typing "make foobar" results in this:
@make foobar
?MAKE: Don't know how to make foobar
perror() says: No such file or directory
@
Amusingly, "make love" returns this classic reply:
@make love
Not war!
?MAKE: Don't know how to make love
perror() says: No such file or directory
@
Here's the Makefile:
CC = cc
NAME = frotz
C = .c
O = .rel
E = .exe
DFROTZ = d$(NAME)$(E)
OBJ = buffer$(O) err$(O) fastme$(O) files$(O) getopt$(O) hotkey$(O) \
input$(O) main$(O) math$(O) missin$(O) object$(O) \
proces$(O) quetza$(O) random$(O) redire$(O) screen$(O) \
sound$(O) stream$(O) table$(O) text$(O) variab$(O) \
dblorb$(O) dinit$(O) dinput$(O) doutpu$(O) dpic$(O)
dumb: $(DFROTZ)
dfrotz: $(DFROTZ)
$(DFROTZ): $(OBJ)
$(CC) $(CFLAGS) -o $(DFROTZ) $(OBJ)
.c.rel:
$(CC) $(CFLAGS) -c $< -o $@
clean:
delete *.rel
delete *.exe
.SUFFIXES: .exe .rel .c *.h
