16 !! Some notes
17
16 IanMcDonald 18 You can use [DistCC] or [ccache | http://ccache.samba.org/] (or both) to speed up compilation.
19
20 The main trick is to only make ONE target on the command line. i.e. don't try and do this <tt>make -j6 CC=distcc all modules_install</tt> or else the build will get screwed up and the whole thing will get remade each time.
21
22 Instead do this:
23 <verbatim>
24 make -j6 CC=distcc all
25 make modules_install INSTALL_MOD_PATH=~/tmp
26 </verbatim>
18 IanMcDonald 27
28 To update the .config file with questions for new options do a <tt>make oldconfig</tt>
29
30 To output build files to another directory (so you don't mix source and object code) do <tt>make O=outputdir all</tt>
31
32 To make files in just one source code directory do <tt>make dir</tt>. To make the modules in a directory and link them do <tt>make M=dir</tt>. Remember to put a trailing slash after the directory name.
33
34 NB The above two may require you to have built your config etc first.
35
19 IanMcDonald 36 To enable extra error checks when compiling do <tt>make EXTRA_CFLAGS=-W</tt>.

18 IanMcDonald 54 It has also been suggested to use kgdb with qemu and/or kgdboe to help with debugging.
