Hi
When I typping make clean in terminal,The following message is 
issued:address@hidden:~/ptsgcodes/xpdp1/src$ make clean
rm: cannot remove `*~': No such file or directory
make: *** [clean] Error 1
my makefile is:
##
##           PDP1 Makefile 
##
FILE_EXT = linux
##
XGPATH = /usr/local/lib/xgrafix
##           Gas type for the mcc package.  Uncomment only one.
##
##
##
EXEC = ../bin/xpdp1.$(FILE_EXT)
##
CC = gcc
##
##      C compiler.  Normally gcc.
##
CFLAGS= -g -I$(XGPATH) -DPDP1PATH=\"$(HOME)/xpdp1/src\" 
##
##      Flags used for compiling.  -O2 for optimization, which is optional.
##           If the X11 include files are not located in /usr/include/X11, you
##           must specify the directory as a flag prefixed by -I.  For 
instance, 
##           if the include files for X11 are located in /usr/local/include, 
the 
##           flag -I/usr/local/include must also be passed.
##
LIBS  = -L$(XGPATH) -L/usr/local/lib -L/usr/X11R6/lib -lXGC250 -ltk -ltcl -lXpm 
-lX11 -lm -ldl 
##
##           Libraries and their directories used in loading.  Normal is -lm 
and -lX11
##           for the Math and X11 libraries, which is NOT optional.  On Unicos, 
-lnet
##           is also used.  If the X11 libraries are not located in 
/usr/lib/X11, you
##           must also specify the directory as a flag prefixed by -L.  For 
instance,
##           if the include files for X11 are located in /usr/local/lib, the 
flag
##           -L/usr/local/lib must also be passed.  On Sun, use -Bstatic to 
avoid
##           problems with differing versions of OS.  Man cc for more 
information on flags.
