I'm attempting a port of the 1986 Berkeley tools to a Mentor DN3000. I've successfully run 'make' on the meg subdirectory, but I run into problems when I try the example in the documentation. It goes something like this: INPUTS: INIT OP1 OP2 SWR MACK; OUTPUTS: WAIT MINIT MRD SACK MWR DLI; -- Define the encoding for the processor operations -- The C preprocessor does textual substitions on these macros. #define OP OP1 OP2 #define NOP 0 0 #define HALT 0 1 #define READ 1 0 #define WRITE 1 1 #define XOP ? ? . . . When I type meg multibus.in I get the error message "unexpected token IDENTIFIER on line 6" Has anyone experienced anything like this before? If so, how did you fix it? For now, I'll just have to live with substitions where these macros occur, but I'd love to use the preprocessor. Thanks in advance, Dave Landis NCR Corp. 3718 N.

You must run "cpp" (the C-preprocessor) on your input file to perform those "#define" subsitution first. Do it like this: /lib/cpp -P in-file-name > temp-file meg -e temp-file > out-file-name -- Nai Chi Lee "It is difficult to make something foolproof because fools are so ingenious." [Anon]
