1 The following section gives some tips and tricks on how to use efficiently
6 The buildroot allows you to recompile the full environment or only parts of it
9 For instance if you want to recompile the toolchain after you made any change to it
16 Which will clean, compile and install the toolchain. The command actually expands to the
27 Of course, you could only choose to recompile one or several of the toolchain components
36 will clean, compile and install busybox (if selected to be installed on the final rootfs).
38 Supposing that you made changes to the Linux kernel, but do not want to recompile everything,
53 OpenWrt integrates quilt in order to ease the package, kernel and toolchain
56 Quilt intends to replace an old workflow, where you would download the new
57 source file, create an original copy of it, an a working copy, then try to
59 quilt allows you to update and fold patches into other patches easily.
61 Quilt is used by default to apply Linux kernel patches, but not for the other
73 Some patches are likely to fail since the vanilla kernel we are patching
75 We will use quilt to get them applying cleanly again. Follow this procedure
76 whenever you want to upgrade the kernel using previous patches:
80 \item make target/linux/compile (uncompress the kernel and try to apply patches)
81 \item if patches failed to apply:
83 \item quilt push -a (to apply patches where quilt stopped)
84 \item quilt push -f (to force applying patches)
85 \item edit .rej files, apply the necessary changes to the files
99 packages. If you want to use quilt in the same way, you should set the QUILT environment
100 variable to 1, e.g:
106 Will generate the patch series file and allow you to update patches just like we described
