hi, sorry for cross posting but may be someone on the packaging/rpm side can help me. i'm getting really angry about the debug packages:-) 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? imho if i can know the answer to this question i can solve my only remaining issue with generated spec file for mingw. if why this in the spec file working: ------------------------------------ %define __debug_install_post %{mingw_debug_install_post} ------------------------------------ while this not: test: ------------------------------------ echo "%define __debug_install_post %{mingw_debug_install_post}" ------------------------------------ and in the spec file: ------------------------------------ %global test sh /tmp/test %{expand:%(%{test})} ------------------------------------ ??? the same thing is working for all other macro except for __debug_install_post. thanks in advance. regards.

Did you check: https://fedoraproject.org/wiki/Packaging/Guidelines#.25global_preferred_over...
There are some explanations there.
Best regards, Pierre

yes but still don't know why can't be used at toplevel and why can't be generated by script.

I can't tell you why without knowing more about what's being expanded but -- %global is evaluated when it is defined whereas %define is evaluated when it is used.
Does that help?

not really. so why this line: ------------------------------------ %define __debug_install_post %{mingw_debug_install_post} ------------------------------------ run the %mingw_debug_install_post right after the %install phase, while this two line do not: ------------------------------------ %global test 1 %{?test: %define __debug_install_post %{mingw_debug_install_post}} ------------------------------------ neither ------------------------------------ %define __debug_install_post %{mingw_debug_install_post} ------------------------------------ thanks.

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
