Hmmm. I tried make 3.77 from make-3.77-mingw32.zip.
It does fix my original problem. However it seems to have real problems
with libraries and their dependencies.
I've been trying to generate a sample makefile but I can't get make to do
_anything_ interesting in a test case.
But try this
================================================================
MARK = Mark
# Turn off default library rule
(%): %
> $(MARK)
LIB = mylib.a
OBS = $(LIB)(f1.o) $(LIB)(f2.o)
All: $(OBS)
# making $@ due to $?
=================================================================
I know this doesn't do anything useful but it just demonstrates a problem.
The proper makefile generates a load of objects and then puts them into the
library all in one go.
touch f1.o f2.o
make
I expect to get:
-------------------
> Mark
> Mark
# making All due to f1.o f2.o
-------------------
On cygwin all I get is
make: *** No rule to make target `mylib.a(f1.o)', needed by `All'. Stop.
This works on the make versions I listed previously but does not work on
cygwin using make 3.76 or 3.77
I'm really puzzled how the cygwin developers manage to use this make.
The problem I was trying to demonstrate is that the '# making' line is
printed as
# making All due to mylib.a(f1.o) mylib.a(f2.o)
which is what I get when running this on my real makefile. This is
definitely wrong as the make documentation clearly states that $? expands
the library members and not the full path.
I think I will just give up trying to go down this route as make 3.75 seems
to work perfectly well.
Thanks for your help.
Kevin
