The makefile content is as follows:

Cc = gcc
Cflags =-g-d_gnu_source
Lflags =
Ofiles = collect. O process. O util. O source_db.o
Headers = clink. h

Files = copyright makefile clink.doc clink. h collect. C process. c util. c source_db.c

%. O: %. C $ (headers)
$ (CC) $ (cflags)-C $ <

Clink: $ (ofiles)
$ (CC) $ (lflags)-O clink $ (ofiles)-LM

Tar:
Rm-F clink.1.0 /*
CP $ (Files) clink.1.0
Tar-CVF clink.1.0.tar clink.1.0
Tar-CZF clink.1.0.tar.gz clink.1.0

Note: I added the source_db part in makefile. Please tell me why this error occurs.
