Description hjl 2001-04-19 15:12:11 UTC 
There is no easy to tell from a spec file if we are cross-building
a rpm. You can use

%if %{_target_cpu} != %{_build_cpu}
...
%endif

But it doesn't work with

# rpm --target=i686 ...

on ia32. I think we need _build_arch so that we can do

%if %{_arch} != %{_build_arch}
...
%endif

Add _build_arch
Comment 2 Jeff Johnson 2001-07-17 17:21:40 UTC 
These are rpm-build, not rpm, issues ...
Comment 3 Jeff Johnson 2001-07-28 13:06:01 UTC 
Fixed in my next checkin, should be in rpm-4.0.3-0.84.
Comment 4 hjl 2001-07-28 14:52:07 UTC 
I have added 

%if %{_arch} != %{_build_arch}
%define cross_compile 1
%else
%define cross_compile 0
%endif
%{?do_cross_compile:%define cross_compile 1}

to many spec files. It will be nice for rpm to define
%{cross_compile} automatically.
