Cross Architecture Build

Hey guys, can anybody help me with cross build.
I’m trying to build my project for openSUSE:Factory:ARM:standard repository in chroot.
But every time i got an error.

osc build openSUSE_Factory_ARM armv7l qbs.spec --clean

Hi
For a start please don’t run as root user, you can add yourself via visudo and build as your user and add the su-wrapper in your .oscrc file!


# Wrapper to call build as root (sudo, su -, ...)
# NOTE: use visudo, <username> ALL = NOPASSWD: /usr/bin/build
su-wrapper = sudo

It looks like your missing the qemu-linux-aarch64 package, see the errors at 9secons in your log file.

#3
  1. I’m running as normal user, and I have “su-wrapper = sudo” settings in .oscrc
  2. I’m trying to build armv7l arch, so there is no need in binfmt handlers for aarch64. Anyway I have tried that one.
  3. I can reproduce this error in public build.opensuse.org. x86 and x86_64 arch works fine. But armv7l fails with kernel panic inside kvm and restart build process (It is building for about 2 days and I can’t stop that). https://build.opensuse.org/package/show/home:zaitsme:qbs/qbs

openSUSE:Factory:ARM/standard repo is for building native on armv7l hardware. You need to build against openSUSE:Factory:ARM/qemu repo instead to be able to build arm on x86_64.

#5

Thank you! Everything works fine know.

Houston, we have another problem…

It’s works in build.opensuse.org, but doesn’t work in private installation.
When I tried to build for openSUSE:Factory:ARM/standard, I got a problem, which I described above.
But when I changed the repo name to “qemu”, the task remains in scheduled state forever.

My project meta:


<project name="qbs">
  <title>qbs</title>
  <description>qbs test</description>
  <person userid="Admin" role="maintainer"/>
  <repository name="openSUSE_Factory_ARM">
    <path project="openSUSE.org:openSUSE:Factory:ARM" repository="qemu"/>
    <arch>armv7l</arch>
  </repository>
</project>

My project config:


%ifarch armv7l armv7hl
Hostarch: x86_64
Preinstall: qemu-linux-user
ExportFilter: ^qemu-linux-user.*\.x86_64\.rpm$ . armv7l armv5el
%endif

Any suggestions.
