If you have built your toolchain, it may be nice to reuse the same toolchain on other machines or to share it with other developers.

Creating a Standard Development Environemnt

To realise this, create a container for the directory buildroot and copy the necessary files into it. You can choose between a tarball or filesystem image, which can be loop mounted into your running Linux development machine.

Tarball

Creation

To create a tarball with all binaries and include files, run:

$ tar czf sde-wgt-toolchain.tar.gz openwgt-dev/buildroot/build_mipsel/staging_dir

The tarball will created as sde-wgt-toolchain.tar.gz.

Usage

To extract it, run:

$ TOOLCHAIN_PATH=/sde-wgt-toolchain  # or any other location, you prefer
$ mkdir -p $TOOLCHAIN_PATH
$ tar xzf sde-wgt-toolchain.tar.gz -C $TOOLCHAIN_PATH --no-same-owner

FS Image

If you choose this option you have to select a filesystem, that will contain your toolchain later. I suggest to use cramfs. Cramfs supports encryption and you do not need to create a block device image. Additionally the contents of this image become read-only status later and protected against modifications.

Creation

Create the directory structure:

$ mkdir -p toolchain/openwgt-dev/buildroot/build_mipsel

Move your staging_dir directory:

$ mv openwgt-dev/buildroot/build_mipsel/staging_dir toolchain/openwgt-dev/buildroot/build_mipsel

Finally create the cramfs image (util-linux package):

$ /sbin/mkfs.cramfs -E toolchain sde-wgt-toolchain.cramfs

Usage

Make mount point:

$ mkdir /sde-wgt-toolchain

Mount the image:

$ mount -o loop,ro sde-wgt-toolchain.cramfs /sde-wgt-toolchain
