This makes code bigger and uses - some GNU extensions in libc. You probably only need this option - if you plan to run busybox on desktop. - -choice - prompt "Buffer allocation policy" - default INITRAMFS_BUSYBOX_FEATURE_BUFFERS_USE_MALLOC - help - There are 3 ways BusyBox can handle buffer allocations: - - Use malloc. This costs code size for the call to xmalloc. - - Put them on stack. For some very small machines with limited stack - space, this can be deadly. For most folks, this works just fine. - - Put them in BSS. This works beautifully for computers with a real - MMU (and OS support), but wastes runtime RAM for uCLinux.

If enabled, - busybox will use /dev/ptmx for the master side of the pseudoterminal - and /dev/pts/<number> for the slave side. Otherwise, BSD style - /dev/ttyp<number> will be used.

This is typically done by exec'ing - /proc/self/exe. - This may affect shell, find -exec, xargs and similar applets. - They will use applets even if /bin/<applet> -> busybox link - is missing (or is not a link to busybox). However, this causes - problems in chroot jails without mounted /proc and with ps/top - (command name can be shown as 'exe' for applets started this way). - -config INITRAMFS_BUSYBOX_BUSYBOX_EXEC_PATH - string "Path to BusyBox executable" - default "/proc/self/exe" - help - When Busybox applets need to run other busybox applets, BusyBox - sometimes needs to exec() itself.

This will have no effect if your kernel or your C - library lacks large file support for large files.

Otherwise, leave it set to 'N'. - -config INITRAMFS_BUSYBOX_CROSS_COMPILER_PREFIX - string "Cross Compiler prefix" - default "" - help - If you want to build BusyBox with a cross compiler, then you - will need to set this to the cross-compiler prefix, for example, - "i386-uclibc-". - - Note that CROSS_COMPILE environment variable or - "make CROSS_COMPILE=xxx ..." will override this selection. - - Native builds leave this empty. - -config INITRAMFS_BUSYBOX_EXTRA_CFLAGS - string "Additional CFLAGS" - default "" - help - Additional CFLAGS to pass to the compiler verbatim. - -endmenu - -menu 'Debugging Options' - -config INITRAMFS_BUSYBOX_DEBUG - bool "Build BusyBox with extra Debugging symbols" - default n - help - Say Y here if you wish to examine BusyBox internals while applets are - running.

You - should always leave this option disabled for production use. - - dmalloc support: - ---------------- - 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 - - Electric-fence support: - ----------------------- - This enables compiling with Electric-fence support. Electric - fence is another very useful malloc debugging library which uses - your computer's 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. - - -config INITRAMFS_BUSYBOX_NO_DEBUG_LIB - bool "None" - -config INITRAMFS_BUSYBOX_DMALLOC - bool "Dmalloc" - -config INITRAMFS_BUSYBOX_EFENCE - bool "Electric-fence" - -endchoice - -config INITRAMFS_BUSYBOX_INCLUDE_SUSv2 - bool "Enable obsolete features removed before SUSv3?" - default y - help - This option will enable backwards compatibility with SuSv2, - specifically, old-style numeric options ('command -1 <file>') - will be supported in head, tail, and fold.
