The following bug causes a core dump on Vaxen but not on Suns when doing
make -p. It is caused by the variable MAKELEVEL being improperly set.
In variable.c change:
(void) define_variable ("MAKELEVEL", 9, buf);
into
(void) define_variable ("MAKELEVEL", 9, buf, o_default, 0);
I have also found a bug in variable expansions which causes the following
makefile to produce:
make: *** No way to make target `test/lib.a'. Stop.
-- Makefile
DESTLIB= ./test
all: $(DESTLIB)/lib.a
$(DESTLIB)/lib.a: a.o
ar crl a.o $(DESTLIB)/lib.a
ranlib lib.a
--
If the value of DESTLIB does not begin with "./" it works fine, I have not
had time to trace the bug but I suspect variable expansion as the following
piece of a make -p shows the expansion has garbage at the end.
test/lib.a
STLIB=./test:
depends on: a.o
commands to execute (from `T.m', line 6):
ar crl a.o $(DESTLIB)/lib.a
ranlib lib.a
53 files in 1007 hash buckets (average 0 files per bucket)
The precise garbage that appears between test/lib.a and the : varys from
machine to machine and as you change the makefile.
