Make behavior on TOPS20 Panda distribution - test-drb@ccmp.vtda.org

11 Mar 2020

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
