Error with make

[Amit Basnak]

Dear friends

While compiling C files under HP-UX with make , im getting the the error as follows
$HOME/xmlrpc/make-3.81/make
/orainst/rcsinbg1/xmlrpc/make-3.81/make -C cpp/ all
make: *** cpp/: No such file or directory. Stop.
make: *** [cpp/all] Error 2

The Makefile has been modified to include all the required C files. Still I dont understand why it still looks for cpp files which results in Make failure
Can anyone throuw some light on this ?
Thanks
Amit

Assuming you're typing "$HOME/xmlrpc/make-3.81/make", the next line looks like Make echoing the command being executed. That command would come from some rule in the Makefile. The command "make -C cpp/ all" is telling make to change into the directory "cpp/" and execute the Makefile in that directory; apparently there's no such directory. Without seeing your Makefile, I can't tell you why Make is trying to do this; but that's what it's doing.

Thanks Ernest

Here is my Makefile code which contains cpp/all

all: $(PROGS)
65
66 ifeq ($(ENABLE_CPLUSPLUS),yes)
67 all: cpp/all
68 endif
69
70 .PHONY: cpp/all
71 cpp/all:
72 $(MAKE) -C $(dir $@) $(notdir $@)
73
74 $(CLIENTPROGS):%:%.o
75 $(CCLD) -o $@ $(LDFLAGS) $^ $(LDADD_CLIENT)
76
77 $(SERVERPROGS_CGI):%.cgi:%_cgi.o
78 $(CCLD) -o $@ $(LDFLAGS) $^ $(LDADD_SERVER_CGI)
79
80 $(SERVERPROGS_ABYSS):%:%.o
81 $(CCLD) -o $@ $(LDFLAGS) $^ $(LDADD_SERVER_ABYSS)
82
83 gen_sample_add_xml:%:%.o
84 $(CCLD) -o $@ $(LDFLAGS) $^ $(LDADD_BASE)

OK, well, this is the rule that expands into the command that throws the error:

cpp/all:
        $(MAKE) -C $(dir $@) $(notdir $@)

and it's obvious how it expands into the command line you see in your error message. So this is pretty straightforward stuff: you're asking for make to cd into the "cpp" directory before doing anything. Is there such a directory? If not, then, well, that's the problem -- why is there such a rule (the default rule, in fact) if there's no such directory that needs building?

Ernest thanks again for your comments.
Well This makefile changes done by someone else and hes no loger in te company so Im looking into this.
I dont think it will affect if I comment this line
Thanks again
Amit

If you comment that line, then the makefile won't do anything at all, since cpp/all is the default target!
