26 # With a modern GNU make(1) (highly recommended, that's what all the
27 # developers use), all of the following configuration values can be
28 # overridden at the command line. For example:
29 # make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
31 # If you want a static binary, turn this on.
34 # Set the following to `true' to make a debuggable build.
35 # Leave this set to `false' for production use.
36 # eg: `make DODEBUG=true tests'
37 # Do not enable this for production builds...
40 # This enables compiling with dmalloc ( http://dmalloc.com/ )
41 # which is an excellent public domain mem leak and malloc problem
42 # detector. To enable dmalloc, before running busybox you will
43 # want to first set up your environment.
44 # eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
45 # Do not enable this for production builds...
48 # If you want large file summit support, turn this on.
49 # This has no effect if you don't have a kernel with lfs
50 # support, and a system with libc-2.1.3 or later.
51 # Some of the programs that can benefit from lfs support
52 # are dd, gzip, mount, tar, and mkfs_minix.
53 # LFS allows you to use the above programs for files
57 # If you have a "pristine" source directory, point BB_SRC_DIR to it.
58 # Experimental and incomplete; tell the mailing list
59 # <busybox@opensource.lineo.com> if you do or don't like it so far.

63 # to something more interesting, like "powerpc-linux-".
