-Buildroot2 TODOs
-
-- fix packages/Makefile.autotools.in to use a package-imposed patchdir
- (Ivan Kuten)
-- convert all packages that use autoconf to use the infrastructure of
- packages/Makefile.autotools.in
-- fix setting of flags for packages
-
-- coreutils: use make install-strip to install the packages. For now,
- it fails beause even if we pass STRIP="/path/to/$(ARCH)-strip", the
- coreutils build system uses the host strip to strip target
- binaries. The ./configure execution done by Buildroot properly
- detects the cross-strip, but when running make, build-aux/missing
- gets run, complains about aclocal-1.10c and atuomake-1.10c not being
- present, and rerun the configuration... with the wrong environment
- variables (STRIP= is missing). An autoreconf on this package is
- probably necessary.
2) select the packages you wish to compile
3) run 'make'
4) wait while it compiles
-5) Use your shiny new root filesystem. Depending on which sortof
+5) Use your shiny new root filesystem. Depending on which sort of
root filesystem you selected, you may want to loop mount it,
chroot into it, nfs mount it on your target device, burn it
to flash, or whatever is appropriate for your target system.
You do not need to be root to build or run buildroot. Have fun!

-<h2>Testing Buildroot for an Architecture</h2>
-
-<p>
-<h4>scripts/mkpkg script</h4>
-If you want to test the build of a single package you can use the mkpkg script.
-</p>
-<p>
-<li>$ scripts/mkpkg PACKAGE</li>
-</p>
-<p>
-Will make the board, and save the result in a log file.
-The log file resides in
-<li>$ log/OK/PACKAGE.log.OK</li>
-</p>
-<p>
-if the build succeeds and in
-<li>$ log/OK/PACKAGE.log.FAIL</li>
-</p>
-<p>
-if it cannot complete.
-</p>
-
-<p>
-By creating an alias
-<li>alias mk=scripts/mkpkg</li>
-</p>
-<p>
-it is enough to type
-<li>$ mk PACKAGE</li>
-</p>
-<p>
-mkpkg will only print out the <h4>{PACKAGE}......OK</h4> or <h4>{PACKAGE}......FAIL</h4>
-depending on success or failure making it easy to get an overview
-of the status of this specific architecture.
-</p>
-<p>
-It is recommended to build a simple board before running the test
-to get some basic things done.
-</p>
-<p>
-<h4>scripts/buildall.sh script</h4>
-</p>
-<p>
-By running this script you will run scripts/mkpkg on
-a lot of the packages available in Buildroot.
-</p>
-<p>
-You need to run the script while in the TOP directory.
-I.E: Where you typically run make.
-</p>
-<p>
-There are a few lacking, for no very good reason,
-but these can be easily added.
-</p>
-<p>
-Note that some packages will not build properly
-if you do not enable them using makeconfig.
-</p>
-<p>
-Examples are:
-<li>freetype</li>
-<li>socat</li>

- hints on capabilities, but is not yet complete.
- </p>
-
- <p>
- It will generate a set of scripts which will facilitate downloading
- the kernel and root file system using tftp and will also
- add commands to store into and retrieve from flash

- the root file system and both this machine and the NFS server are powering up
- simultaneously. The NFS server could take a lot longer to boot, and waiting
- for this to boot may be neccessary for proper operation.

- The "fs-date" is added at the end.
- </p>
-
- <p>
- <h3><code>ver<code></h3>

-<h2>Buildroot patch structure</h2>
-
-<p>
-<h4>Keeping track of applied patches</h4>
-Whenever a patch is applied to a source code directory in buildroot, a text file named .applied_patches_list is created inside that source directory.
-This file contains a list of all the patch filenames that were applied to that source code, just for reference.
-</p>
-
-<p>
-<h4>Linux kernel patches</h4>
-The Linux kernel has several patch levels available for it in the buildroot patch system.
-Buildroot first downloads the chosen kernel source from the mirror site, followed by any selected minor patch.
-Buildroot then extracts the kernel source from the compressed file and applies the minor patch, if one was chosen.
-After extracting the source and applying the official minor patch, buildroot looks for more patches in the following locations and in the order shown:
-
-<ol>
-<li> a custom, user downloaded kernel patch can be located in $(DL_DIR) and the filename is stored as $(LINUX26_BSP_PATCH) </li>
-<li> Atmel keeps their official kernel patches in target/device/Atmel/Linux/kernel-patches with subdirectories for each kernel release.
-They also keep any board-specific patches in $(BR2_BOARD_PATH) </li>
-<li> globally available patches are kept in toolchain/kernel-headers </li>
-<li> IPMI (<a href="http://www.intel.com/design/servers/ipmi/ipmi.htm">Intelligent Platform Management Interface</a>)
-kernel patches are kept in toolchain/kernel-headers/ipmi </li>
-<li> LZMA kernel compression support patches are kept in toolchain/kernel-headers/lzma </li>
-<li> <a href="http://www.realtimelinuxfoundation.org/downloads/downloads.html">Real-time Linux kernel</a> patches are kept in $(LINUX_RT_SOURCE) </li>
-<li> <a href="http://www.openswan.org/">Openswan</a> kernel patches are kept in package/openswan </li>
-</ol>
-</p>
-
- <p>
- <h4>Package source patches</h4>
- Any patches for the Linux programs supported by buildroot are kept in that program's corresponding package/ directory.
- </p>
-
- <p>
- <h4>How the patching is done</h4>
-Patches are applied in buildroot by running a shell script called toolchain/patch-kernel.sh with three arguments. The first argument is the target directory
-where the source code to be patched is saved. The second argument is the directory where the patch is saved. The third argument is the filename pattern
-to match when looking in the patch directory. The third argument can include wildcards to select multiple patch files.
