I have set up a directory structure to put the .obj files in after running make and instead of putting the .obj in the subdirectory i wanted, it is put in the same directory thatI ran make from. I changed the builtins.mak file by changing the reference to the .obj files and now when I compile, I get a "FATAL: Command arguments too long!" error and I don't get it with the old builtins.mak. I compared the two and the only changes I see are dealing with the """ .c.obj:$(CC) $(CFLAGS) -c -o$@ $&.c" and the original is ".c.obj:$(CC) $(CFLAGS) /c $&.c". Do I have a problem with the switches like "/c" or "-o$@"??? Any help is appreciated.
