25 # With a modern GNU make(1) (highly recommended, that's what all the
26 # developers use), all of the following configuration values can be
27 # overridden at the command line. For example:
28 # make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
30 # If you want to add some simple compiler switches (like -march=i686),
31 # especially from the command line, use this instead of CFLAGS directly.
32 # For optimization overrides, it's better still to set OPTIMIZATION.
35 # If you want a static binary, turn this on.
38 # Set the following to `true' to make a debuggable build.
39 # Leave this set to `false' for production use.
40 # eg: `make DODEBUG=true tests'
41 # Do not enable this for production builds...
44 # Setting this to `true' will cause busybox to directly use the system's
45 # password and group functions. Assuming you use GNU libc, when this is
46 # `true', you will need to install the /etc/nsswitch.conf configuration file
47 # and the required libnss_* libraries. This generally makes your embedded
48 # system quite a bit larger... If you leave this off, busybox will directly
49 # use the /etc/password, /etc/group files (and your system will be smaller, and
50 # I will get fewer emails asking about how glibc NSS works). Enabling this adds
51 # just 1.4k to the binary size (which is a _lot_ less then glibc NSS costs),
52 # Most people will want to leave this set to false.
53 USE_SYSTEM_PWD_GRP = true
55 # This enables compiling with dmalloc ( http://dmalloc.com/ )
56 # which is an excellent public domain mem leak and malloc problem
57 # detector. To enable dmalloc, before running busybox you will
58 # want to first set up your environment.
59 # eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
60 # Do not enable this for production builds...
63 # If you want large file summit support, turn this on.
64 # This has no effect if you don't have a kernel with lfs
65 # support, and a system with libc-2.1.3 or later.
66 # Some of the programs that can benefit from lfs support
67 # are dd, gzip, mount, tar, and mkfs_minix.
68 # LFS allows you to use the above programs for files
72 # If you have a "pristine" source directory, point BB_SRC_DIR to it.
73 # Experimental and incomplete; tell the mailing list
74 # <busybox@opensource.lineo.com> if you do or don't like it so far.

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