I expect that y.tab.c and lex.yy.c would crash the make depend process in
the same way, were they actually submitted to the "makedep" program.
The Makefile in tools/wrc that configure built for me includes this
(without my changes):
depend: $(MAKEDEP) $(C_SRCS) $(RC_SRCS) $(EXTRA_SRCS) $(SUBDIRS:%=%/__depend__)
$(MAKEDEP) $(DIVINCL) -C$(SRCDIR) $(C_SRCS) $(RC_SRCS) $(EXTRA_SRCS)
That same Makefile sets these interesting variables (again, without my
changes):
C_SRCS = \
dumpres.c \
genres.c \
newstruc.c \
preproc.c \
readres.c \
utils.c \
wrc.c \
writeres.c
EXTRA_SRCS = parser.y parser.l ppl.l ppy.y ppy.tab.c lex.ppl.c
and does not set RC_SRCS at all.
So, the only files given to makedep on the command line are:
dumpres.c, genres.c, newstruc.c, preproc.c, readres.c, utils.c,
wrc.c and writeres.c (from C_SRCS)
and parser.y, parser.l, ppl.l and ppl.y (from EXTRA_SRCS)
which all exist in the source directory, and:
ppy.tab.c and lex.ppl.c
which are generated in the build directory. The other source files
generated in the build directory:
lex.yy.c and y.tab.c
are not included in any of the variables on the makedep command line.
Did tools/wrc/Makefile get built wrong? Should the lex.yy.c and y.tab.c
files have been included in the "makedep" command?
Curiously,
Matt.
