28 # What OS are you compiling busybox for? This allows you to include
29 # OS specific things, syscall overrides, etc.
32 # With a modern GNU make(1) (highly recommended, that's what all the
33 # developers use), all of the following configuration values can be
34 # overridden at the command line. For example:
35 # make CROSS=powerpc-linux- CONFIG_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
37 # If you want to add some simple compiler switches (like -march=i686),
38 # especially from the command line, use this instead of CFLAGS directly.
39 # For optimization overrides, it's better still to set OPTIMIZATION.
42 # If you want a static binary, turn this on.
45 # Set the following to `true' to make a debuggable build.
46 # Leave this set to `false' for production use.
49 # This enables compiling with dmalloc ( http://dmalloc.com/ )
50 # which is an excellent public domain mem leak and malloc problem
51 # detector. To enable dmalloc, before running busybox you will
52 # want to first set up your environment.
53 # eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
54 # Do not enable this for production builds...
57 # Electric-fence is another very useful malloc debugging library.
58 # Do not enable this for production builds...
61 # If you want large file summit support, turn this on.
62 # This has no effect if you don't have a kernel with lfs
63 # support, and a system with libc-2.1.3 or later.
64 # Some of the programs that can benefit from lfs support
65 # are dd, gzip, mount, tar, and mkfs_minix.
66 # LFS allows you to use the above programs for files
70 # If you have a "pristine" source directory, point CONFIG_SRC_DIR to it.
71 # Experimental and incomplete; tell the mailing list
72 # <busybox@busybox.net> if you do or don't like it so far.
75 # If you are running a cross compiler, you may want to set CROSS
76 # to something more interesting, like "arm-linux-".
