As far as I can tell, the rpm-list went defunct circa 2008 so I'm asking here. No doubt someone will let me know if this is not OK.
I'm trying to build an RPM on a CentOS VM targeted to run on an ARM architecture machine.
I have a test program, prime, that I cross compiled on my VM and when I copy it onto my target machine it runs correctly. Now I want to package it in an RPM.
On my target machine, I run $ uname -m armv71
so on the VM I wrote my spec file and ran $ rpmbuild -ba --target armv71 prime.spec ... processing files: prime-1.0-1.armv71 unknown, 0: Warning using regular magic file '/etc/magic' Requires(rpmlib): rpmlib(payloadFilesHavePrefix) <= 4.0-1 rpmlib(CompressedFileNames) <= 3.0.4-1 ... Wrote /home/steve/rpmbuild/RPMS/armv71/prime-1.0-1.armv71.rpm ...
So it seems that some parts of rpm realize that I've cross compiled and some parts don't. Any ideas on how to get rid of these warning messages? I tried putting 'Autoreq: 0' in the spec file but that didn't help.
A second problem is that when I go to install the rpm on the target machine, I get an error saying that the architecture doesn't match. I had to use --ignorarch to get it to install. What does rpm use to determine what the architecture is if not uname?
With the --ignorearch option, the RPM installs and the program runs as expected.
Thanks, Steve

I would recommend using "Mock" for this as it would both provide a clean build environment (chroot) and the ability to cross compile easily.
Once you get mock all configured and set up, it's actually a really nice tool and handy :-). I highly recommend it.
Good luck! :-)
