does anybody who can tell me the real reason of why: ------------------------------------ %define __debug_install_post %{mingw_debug_install_post} ------------------------------------ works why ------------------------------------ %global __debug_install_post %{mingw_debug_install_post} ------------------------------------ not?

Now if you say that buildsubdir definition isn't available when you are setting __debug_install_post, it means you need to use lazy expansion. This is probably the reason why %define works for you but %global doesn't: %global is expanded at definition time. If you really want to use %global instead of %define, you could try forcing lazy expansion by escaping %: %global __debug_install_post %%{mingw_debug_install_post}                             ^^ force lazy expansion
