Hi, I've creted a .spec file for a rpm. The distfile are precompiled binary files for i386 and x86_64 so I'm just repackaging it with the proper directory hierarchy. Vendor rpm has both executables for i386 and x86_64. My package has binary for appropriate arch. As far as I understand, if the source (dist files) are working on %{ix86} and x86_64 I should have the following line in .spec: ExclusiveArch: %{ix86} x86_64 Then I'm building the package on i686 host with command: $ rpmbuild -ba --clean megacli.spec $ rpmbuild -ba --clean --target x86_64 megacli.spec and that creates everything what I need. Now I have problem when I install any of those packages on x86_64 host. On x86_64 system I can install both packages and there will be no conflict message but I would like to get error when installing, or I would like that rpm will be replaced when I will run rpm --upgrade. How I can write .spec file to achieve that? # rpm -Uhv megacli-2.00.12-1.2.2.i386.rpm Preparing... ########################################### [100%] 1:megacli ########################################### [100%] # rpm -Uhv megacli-2.00.12-1.2.2.x86_64.rpm Preparing... ########################################### [100%] 1:megacli ########################################### [100%] # rpm -q --last megacli megacli-2.00.12-1.2.2 Tue 02 Dec 2008 03:59:11 PM GMT megacli-2.00.12-1.2.2 Tue 02 Dec 2008 03:59:05 PM GMT -- best regards q# _______________________________________________ Rpm-list mailing list Rpm-list@xxxxxxxxxxxxx http://lists.rpm.org/mailman/listinfo/rpm-list
