-The following section gives some tips and tricks on how to use efficiently
-OpenWrt on a regular basis and for daily work.
-
-\subsection{Compiling/recompiling components}
-
-The buildroot allows you to recompile the full environment or only parts of it
-like the toolchain, the kernel modules, the kernel or some packages.
-
-For instance if you want to recompile the toolchain after you made any change to it
-issue the following command:
-
-\begin{Verbatim}
-make toolchain/{clean,compile,install}
-\end{Verbatim}
-
-Which will clean, compile and install the toolchain. The command actually expands to the
-following:
-
-\begin{Verbatim}
-make[1] toolchain/clean
-make[2] -C toolchain/kernel-headers clean
-make[2] -C toolchain/binutils clean
-make[2] -C toolchain/gcc clean
-make[2] -C toolchain/uClibc clean (glibc or eglibc when chosen)
-\end{Verbatim}
-
-Of course, you could only choose to recompile one or several of the toolchain components
-(binutils, kernel-headers gcc, C library) individually.
-
-The exact same idea works for packages:
-
-\begin{Verbatim}
-make package/busybox/{clean,compile,install}
-\end{Verbatim}
-
-will clean, compile and install busybox (if selected to be installed on the final rootfs).
-
-Supposing that you made changes to the Linux kernel, but do not want to recompile everything,
-you can recompile only the kernel modules by issuing:
-
-\begin{Verbatim}
-make target/linux/compile
-\end{Verbatim}
-
-To recompile the static part of the kernel use the following command:
-
-\begin{Verbatim}
-make target/linux/install
-\end{Verbatim}
-
-\subsection{Using quilt inside OpenWrt}
-
-OpenWrt integrates quilt in order to ease the package, kernel and toolchain
-patches maintenance when migrating over new versions of the software.
-
-Quilt intends to replace an old workflow, where you would download the new
-source file, create an original copy of it, an a working copy, then try to
-apply by hand old patches and resolve conflicts manually. Additionnaly, using
-quilt allows you to update and fold patches into other patches easily.
-
-Quilt is used by default to apply Linux kernel patches, but not for the other
-components (toolchain and packages).
-
-\subsubsection{Using quilt with kernel patches}
-
-Assuming that you have everything setup for your new kernel version:
-\begin{itemize}
-\item \texttt{LINUX\_VERSION} set in the target Makefile
-\item config-2.6.x.y existing
-\item patches-2.6.x.y containing the previous patches
-\end{itemize}
-
-Some patches are likely to fail since the vanilla kernel we are patching
-received modifications so some hunks of the patches are no longer applying.
-We will use quilt to get them applying cleanly again. Follow this procedure
-whenever you want to upgrade the kernel using previous patches:
-
-\begin{enumerate}
-\item make target/linux/clean (removes the old version)
-\item make target/linux/compile (uncompress the kernel and try to apply patches)
-\item if patches failed to apply:
-\item cd build\_dir/linux-target/linux-2.6.x.y
-\item quilt push -a (to apply patches where quilt stopped)
-\item quilt push -f (to force applying patches)
-\item edit .rej files, apply the necessary changes to the files
-\item remove .rej files
-\item quilt refresh
-\item repeat operation 3 and following until all patches have been applied
-\item when all patches did apply cleanly: make target/linux/refresh
-\end{enumerate}
-
-Note that generic (target/linux/generic-2.6/linux-2.6.x/) patches can be found in
-\texttt{build\_dir/linux-target/linux-2.6.x.y/patches/generic} and platform specific
-patches in \texttt{build\_dir/linux-target/linux-2.6.x.y/patches/platform}.
-
-\subsubsection{Using quilt with packages}
-
-As we mentionned earlier, quilt is enabled by default for kernel patches, but not for
-packages. If you want to use quilt in the same way, you should set the QUILT environment
-variable to 1, e.g:
-
-\begin{Verbatim}
-make package/busybox/{clean,compile} QUILT=1
-\end{Verbatim}
-
-Will generate the patch series file and allow you to update patches just like we described
-before in the kernel case. Note that once all patches apply cleanly you should refresh them
-as well using the following command:
-
-\begin{Verbatim}
-make package/busybox/refresh QUILT=1
-\end{Verbatim}
