I've finally edit conf/i386-pc.rmk, copy-pasted the play.c code and
find/replace with map.c.


Then I run make:
make prompts this:


adrian@adrianpc:~/Desktop/gnu/grub2/grub2_2007_05_31_map$ make
if test "x" = x; then \
           touch conf/i386-pc.mk; \
         else \
            ./genmk.rb < conf/i386-pc.rmk > conf/i386-pc.mk; \
         fi
make: No se hace nada para `all'.

If you check: i386-pc.mk then there is no reference to:
"/map.c"

If I delete i386-pc.mk and run make again:

adrian@adrianpc:~/Desktop/gnu/grub2/grub2_2007_05_31_map$ make
Makefile:111: conf/i386-pc.mk: No existe el fichero o el directorio
if test "x" = x; then \
           touch conf/i386-pc.mk; \
         else \
            ./genmk.rb < conf/i386-pc.rmk > conf/i386-pc.mk; \
         fi
make: No se hace nada para `all'.

and a empty i386-pc.mk file is created.


I check genmk.rb and it is not an executable file.
