Yet another major rework of the BusyBox config system, using the considerably
modified Kbuild system I put into uClibc. With this, there should be no more need to modify Rules.mak since I've moved all the interesting options into the config system. I think I've got everything updated, but you never know, I may have made some mistakes, so watch closely. -Erik

+ If you want to build BusyBox with large file support, then enable

+ bool "Build BusyBox as a static binary (no shared libs)"
+ default n
+ help
+ If you want to build a static BusyBox binary, which does not
+ use or require any shared libraries, then enable this option.
+ This will make BusyBox be considerable larger, so you should
+ leave this option false unless you have a good reason (i.e.
+ your target platform does not support shared libraries, or
+ you are building an initrd which doesn't need anything but
+ BusyBox, etc).
+
+ Most people will leave this set to 'N'.
+
+config DODEBUG
+ bool "Build BusyBox with Debugging symbols"
+ default n
+ help
+ Say Y here if you wish to compile BusyBox with debugging symbols.
+ This will allow you to use a debugger to examine BusyBox internals
+ while applets are running. This increases the size of the binary
+ considerably and should only be used when doing development.
+ If you are doing development and want to debug BusyBox, answer Y.
+
+ Otherwise, answer N.
+
+config DODMALLOC
+ bool "Build BusyBox with dmalloc support"
+ default n
+ depends on DODEBUG && !DOEFENCE
+ help
+ This enables compiling with dmalloc ( http://dmalloc.com/ )
+ which is an excellent public domain mem leak and malloc problem
+ detector. To enable dmalloc, before running busybox you will
+ want to properly set your environment, for example:
+ export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
+ The 'debug=' value is generated using the following command
+ dmalloc -p log-stats -p log-non-free -p log-bad-space -p log-elapsed-time \
+ -p check-fence -p check-heap -p check-lists -p check-blank \
+ -p check-funcs -p realloc-copy -p allow-free-null
+
+ This will make BusyBox be considerable larger and run slower, so
+ you should leave this option disabled for production use.
+
+config DOEFENCE
+ bool "Build BusyBox with Electric-fence support"
+ default n
+ depends on DODEBUG && !DODMALLOC
+ help
+ This enables compiling with Electric-fence support. Electric
+ fence is another very useful malloc debugging library which used
+ your computers virtual memory hardware to detect illegal memory
+ accesses. This support will make BusyBox be considerable larger
+ and run slower, so you should leave this option disabled unless
+ you are hunting a hard to find memory problem.
