RescueOS build HOWTO
|
|
|
|
These instructions are for folks who want to modify RescueOS and make their
|
|
own images. If you just want to use RescueOS on your N900, you'll want to
|
|
get one of the prebuilt images and look at 'documentation.txt' for usage
|
|
info.
|
|
|
|
RescueOS images are modified buildroot images. This source distribution is
|
|
just a collection of config files, patches, etc. that configure and customize
|
|
buildroot builds.
|
|
|
|
You'll need a GNU/Linux system to host the build. You'll need 'git' and
|
|
'quilt' to checkout the RescueOS source and apply our buildroot patches,
|
|
respectively. Once that's done, you'll also need to satisfy buildroot's
|
|
prerequisites; we'll address that later.
|
|
|
|
These files are meant to be used with version 2013.02 of buildroot. (Ports to
|
|
newer versions are welcome.)
|
|
|
|
Start by unpacking the RescueOS and buildroot sources into separate
|
|
directories. We recommend putting the two directories next to each other under
|
|
a common parent directory:
|
|
|
|
$ mkdir rescueos-build
|
|
$ cd rescueos-build
|
|
|
|
Use git to checkout the RescueOS source. It will go into a subdirectory named
|
|
'N900_RescueOS'.
|
|
|
|
$ git clone <rescueos repository url>
|
|
|
|
Fetch, verify, and unpack the buildroot source. It will end up in a
|
|
subdirectory named 'buildroot-2013.02'.
|
|
|
|
$ wget http://www.buildroot.org/downloads/buildroot-2013.02.tar.bz2
|
|
$ wget http://www.buildroot.org/downloads/buildroot-2013.02.tar.bz2.sign
|
|
$ gpg --recv-keys B025BA8B59C36319
|
|
$ gpg --verify buildroot-2013.02.tar.bz2.sign
|
|
$ compare the checksums in buildroot-2013.02.tar.bz2.sign with the actual checksums of buildroot-2013.02.tar.bz2 (it's not a detached signature)
|
|
$ tar --extract --bzip --file buildroot-2013.02.tar.bz2
|
|
|
|
Buildroot's prerequisites are documented in the "System requirements" section
|
|
of the buildroot manual ('buildroot-2013.02/docs/manual/manual.html'). Install them if necessary.
|
|
|
|
Now apply our buildroot patches with quilt.
|
|
|
|
$ cd buildroot-2013.02
|
|
$ QUILT_PATCHES=../N900_RescueOS/buildroot-patches quilt push -a
|
|
|
|
Point buildroot to the RescueOS configuration:
|
|
|
|
$ make defconfig BR2_DEFCONFIG=../N900_RescueOS/buildrootconfig
|
|
|
|
Invoke buildroot to build RescueOS:
|
|
|
|
$ make
|
|
|
|
Buildroot will download and build a whole bunch of packages, starting with the
|
|
cross-compiling toolchain. When it's done, kernel and cramfs images will be
|
|
left in 'buildroot-2013.02/output/images'.
