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.
42 # Setting this to `true' will cause busybox to directly use the system's
43 # password and group functions. Assuming you use GNU libc, when this is
44 # `true', you will need to install the /etc/nsswitch.conf configuration file
45 # and the required libnss_* libraries. This generally makes your embedded
46 # system quite a bit larger... If you leave this off, busybox will directly use
47 # the /etc/password, /etc/group files (and your system will be smaller, and I
48 # will get fewer emails asking about how glibc NSS works). Enabling this adds
49 # just 1.4k to the binary size (which is a _lot_ less then glibc NSS costs).
50 # Note that if you want hostname resolution to work with glibc, you still need
51 # the libnss_* libraries.
52 USE_SYSTEM_PWD_GRP = true
54 # This enables compiling with dmalloc ( http://dmalloc.com/ )
55 # which is an excellent public domain mem leak and malloc problem
56 # detector. To enable dmalloc, before running busybox you will
57 # want to first set up your environment.
58 # eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
59 # Do not enable this for production builds...
62 # Electric-fence is another very useful malloc debugging library.
63 # Do not enable this for production builds...
66 # If you want large file summit support, turn this on.
67 # This has no effect if you don't have a kernel with lfs
68 # support, and a system with libc-2.1.3 or later.
69 # Some of the programs that can benefit from lfs support
70 # are dd, gzip, mount, tar, and mkfs_minix.
71 # LFS allows you to use the above programs for files
75 # If you have a "pristine" source directory, point BB_SRC_DIR to it.
76 # Experimental and incomplete; tell the mailing list
77 # <busybox@opensource.lineo.com> if you do or don't like it so far.
