Hi,
Does make(1)'s special source (not local variable) '.MAKE' work validly ?
I have a try as follows:
% cat Makefile
doit: .MAKE
${MAKE}${MAKEFLAGS} sub
sub:
uname
% make doit
make sub
uname
FreeBSD
% make -n doit
make -n sub
I expect last result to be
make -n sub
uname
'Recursive make' will be widely applicable to our development.
Apparently it seems that these codes are ...
% cd /usr/src/usr.bin/make
% grep -n '\.MAKE[^F]' *.[ch]
parse.c:215:{ ".MAKE", Attribute, OP_MAKE },
str.c:60: argv[0] = Var_Value(".MAKE", VAR_GLOBAL, &p1);
str.c:135: * the first word is always the value of the .MAKE variable.
% grep -n 'OP_MAKE' *.[ch]
job.c:530: noSpecials = (noExecute && !(job->node->type & OP_MAKE));
job.c:1719: if ((gn->type & OP_MAKE) || (!noExecute && !touchFlag)) {
make.h:188:#define OP_MAKE 0x00000200 /* Target is a recurrsive make so its
parse.c:215:{ ".MAKE", Attribute, OP_MAKE },
parse.c:231:{ ".RECURSIVE", Attribute, OP_MAKE },
