Sorry I wanted to make a .a library with AR
> LISGGT_A      = ../lib/libSGGT.a
Therefore I replaced the following section:

 ------------^^^^^^^^^^^^^^^^^ (Cygwin ld does not support that type of
shared library
                               (you need to create a DLL instead
Again sorry I want to make .a library
> .cc.o:

>       @echo ">>>"

With:
all: $(LISGGT_A)
 $(LISGGT_A): $(OBJECTS)
 @echo ">>>"
 @echo ">>> Making library $@
 @echo ">>>"
 $(RM) $@
 $(AR) $(STATIC_LDFLAGS) -o $@ $(OBJECTS) #where STATIC_LDFLAGS=rc

.cc.o:
 @echo ">>>"
 @echo ">>> Compiling $<"
 @echo ">>>"
 $(COMPILE.cc) $(PIC) $<

I know this is possible to make a .a library, as I have done it with another
simpler makefile.
But I don't see how my making a .so or .a library has anything to do with
the fact that it doesn't know howto make a .o file
e.g.
file://MAYA/.../sandro $ make --unix
cd src;make all
make[1]: *** No rule to make target `VRMLVisitor.o', needed by
`../lib/libSGGT.a'.  Stop.
make: *** [all] Error 2

Make version 3.75
This must be a problem with make as it works on un*x machines.
Any Ideas ?

Thank You
