SB2

In Mer, we're currently experimenting with integrating SB2 into OBS to provide a better and more flexible cross compilation method. This is instructions to help you get started testing/developing this project.

WARNING: this is in-development code and may cause damage

Steps

It is assumed you already have a functioning osc+build install on your computer.

• Install modified osc client
  • git clone git://github.com/stskeeps/osc.git
  • cd osc
  • (as root) python setup.py install --prefix=/usr
  • If you are on ubuntu, you might need to install into dist-packages instead of site-packages
• Install modified 'build'
  • git clone git://github.com/stskeeps/obs-build.git
  • cd osc-build
  • (as root) make install

Trying it out

• Register an account on http://webui-ci.tspre.org
• osc -A http://api-ci.tspre.org ls
• (type in your username/password)
• osc -A http://api-ci.tspre.org checkout home:Admin:sb2:noaccel acl
• cd home:Admin:sb2:noaccel acl
• osc build --clean --no-verify Core_armv7l armv7el

In a KVM

• You need to set up so you can do KVM builds
• osc build --clean --no-verify --vm-type=kvm Core_armv7l armv7el

OBS project configuration settings

In the fork of 'build' and Carsten Munk's https://github.com/stskeeps/open-build-service OBS fork, it is now possible to do the following configuration settings

 %ifarch armv7el
 SB2install: packages-to-be-installed-in-root
 SB2flags: --toolchain /opt/cross/bin/armv7l-meego-linux-gnueabi-gcc --qemu /usr/bin/qemu-arm --debug
 %endif

The sb2flags available:

 --toolchain /path/to/your/crosscompiler-gcc/in/tools
 --qemu /path/to/your/dynamic/qemu
 --installmode name-of-sb2-mode-used-for-buildsystem-setup
 --defaultmode name-of-sb2-mode-used-for-rpmbuild
 --debug, will enable SB2 debugging/logs

As an example, current home:Admin:sb2:noaccel project configuration is:

 %ifarch armv7el
 sb2install: sb2-tools-arm
 sb2flags: --toolchain /opt/cross/bin/armv7l-meego-linux-gnueabi-gcc --qemu /usr/bin/qemu-arm --debug
 %endif
