Cross Building Linux

Just a quick note since even if is quite easy to read the Makefile sometimes you’d rather have the solution now.
This is what I use for the efika images. The layout is the following:

/dev/sdc1 on /mnt/efika/boot type vfat (rw)
/dev/sdc2 on /mnt/efika/ type ext4 (rw)

CROSS_COMPILE and INSTALL_MOD_PATH are described quite well in the linux Makefile.
The former tell the configure which toolchain should be used, the latter where to install the modules, pretty easy, isn’t it?

You must be careful to not forget the trailing “-” from the CROSS_COMPILE and you can avoid the trailing “/” in the INSTALL_MOD_PATH

make CROSS_COMPILE=armv7a-unknown-linux-gnueabi- ARCH=arm menuconfig
make CROSS_COMPILE=armv7a-unknown-linux-gnueabi- ARCH=arm
make CROSS_COMPILE=armv7a-unknown-linux-gnueabi- ARCH=arm uImage
make CROSS_COMPILE=armv7a-unknown-linux-gnueabi- ARCH=arm INSTALL_MOD_PATH=/mnt/efika modules_install

In this specific case we need the u-boot tools to bake an uImage, in Gentoo

emerge u-boot-tools

ACR plugins and themes

Recently we decided to move our Turbogears 2 CMS, ACRCMS, from an example of how to use libacr to something more complete. Consequently to this decision we implemented the plugins architecture inside libacr, which permits to add plugins to libacr at run-time.

Until now there were no real plugins, the only available plugins were the three acr slice templates which have been moved from an internal function to a plugin.

Today the first real plugin for ACR has been pushed in a separate branch, the plugin is the Theme engine, which permits to add theme support to ACR. The plugin is available inside the ACRCMS acr_plugins directory and is now loaded by default by ACRCMS, it will be officially part of ACRCMS in the next release.

We decided to distribute it with ACRCMS instead of libacr as we felt that theme management is a function deserved to a CMS, not to a CMF.

For now you can test it from the themable branch of ACR
