Hi,
Just to confirm... This isn't anything to do with tab characters. That was the first thing I checked (mentioned in the original post).
I have done some more digging... Here is the line where the missing separator message comes up.
----------------------------------------------------
$(LIB): $(LIB)($(OBJS)) $(OBJS) <----- ERROR REFERS TO THIS LINE
$(CC) $(CFLAGS) -o $@ $(LDLIBS) $^
----------------------------------------------------
It turns out that when the variable "LIB" is not defined, make is expanding it to be a single space character. On all other platforms that I have used this setup on, an undefined variable comes out as an empty string, and doesn't cause a problem since this expands to an empty rule. Whats more, the test "#ifdef..." comes back with TRUE in this case (should be FALSE). If I define $(LIB) to be empty earlier (ie using the line
---------------
LIB :=
---------------
then it correctly expands the rule and #ifdef works properly. This only breaks down when LIB hasn't been defined...
I mentioned in the original post that this exact setup works fine on Linux, FreeBSD, Solaris, SolarisX86 - Cygwin seems to be the only platform where this happens. Is this a known bug in the Cygwin variant of Make?
Cheers,
Andrew Jacka
