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} |
