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?
i find the reason but don't know how to solve. the problem was %{?buildsubdir} which is not defined in the header part of the spec file just in and after the %setup section. which means it's very hard to define any kind of macro for __debug_install_post in the header part without know which directory contains the compiled code so where have to extract the debug info... any tip?
One of the differences between %global and %define is that %define is lazily expanded, but global is 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
Hope this helps, Kalev
