config BINFMT_ELFbool "Kernel support for ELF binaries"depends on MMU && (BROKEN || !FRV)default y---help---ELF (Executable and Linkable Format) is a format for libraries andexecutables used across different architectures and operatingsystems. Saying Y here will enable your kernel to run ELF binariesand enlarge it by about 13 KB. ELF support under Linux has now allbut replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)because it is portable (this does *not* mean that you will be ableto run executables from different architectures or operating systemshowever) and makes building run-time libraries very easy. Many newexecutables are distributed solely in ELF format. You definitelywant to say Y here.Information about ELF is contained in the ELF HOWTO available from<http://www.tldp.org/docs.html#howto>.If you find that after upgrading from Linux kernel 1.2 and saying Yhere, you still can't run any ELF binaries (they just crash), thenyou'll have to install the newest ELF runtime libraries, includingld.so (check the file <file:Documentation/Changes> for location andlatest version).config BINFMT_ELF_FDPICbool "Kernel support for FDPIC ELF binaries"default ydepends on (FRV || BLACKFIN)helpELF FDPIC binaries are based on ELF, but allow the individual loadsegments of a binary to be located in memory independently of eachother. This makes this format ideal for use in environments where noMMU is available as it still permits text segments to be shared,even if data segments are not.It is also possible to run FDPIC ELF binaries on MMU linux also.config BINFMT_FLATtristate "Kernel support for flat binaries"depends on !MMUhelpSupport uClinux FLAT format binaries.config BINFMT_ZFLATbool "Enable ZFLAT support"depends on BINFMT_FLATselect ZLIB_INFLATEhelpSupport FLAT format compressed binariesconfig BINFMT_SHARED_FLATbool "Enable shared FLAT support"depends on BINFMT_FLAThelpSupport FLAT shared librariesconfig BINFMT_AOUTtristate "Kernel support for a.out and ECOFF binaries"depends on X86_32 || ALPHA || ARM || M68K || SPARC32---help---A.out (Assembler.OUTput) is a set of formats for libraries andexecutables used in the earliest versions of UNIX. Linux usedthe a.out formats QMAGIC and ZMAGIC until they were replacedwith the ELF format.The conversion to ELF started in 1995. This option is primarilyprovided for historical interest and for the benefit of thosewho need to run binaries from that era.Most people should answer N here. If you think you may haveoccasional use for this format, enable module support aboveand answer M here to compile this support as a module calledbinfmt_aout.If any crucial components of your system (such as /sbin/initor /lib/ld.so) are still in a.out format, you will have tosay Y here.config OSF4_COMPATbool "OSF/1 v4 readv/writev compatibility"depends on ALPHA && BINFMT_AOUThelpSay Y if you are using OSF/1 binaries (like Netscape and Acrobat)with v4 shared libraries freely available from Compaq. If you'regoing to use shared libraries from Tru64 version 5.0 or later, say N.config BINFMT_EM86tristate "Kernel support for Linux/Intel ELF binaries"depends on ALPHA---help---Say Y here if you want to be able to execute Linux/Intel ELFbinaries just like native Alpha binaries on your Alpha machine. Forthis to work, you need to have the emulator /usr/bin/em86 in place.You can get the same functionality by saying N here and saying Y to"Kernel support for MISC binaries".You may answer M to compile the emulation support as a module andlater load the module when you want to use a Linux/Intel binary. Themodule will be called binfmt_em86. If unsure, say Y.config BINFMT_SOMtristate "Kernel support for SOM binaries"depends on PARISC && HPUXhelpSOM is a binary executable format inherited from HP/UX. SayY here to be able to load and execute SOM binaries directly.config BINFMT_MISCtristate "Kernel support for MISC binaries"---help---If you say Y here, it will be possible to plug wrapper-driven binaryformats into the kernel. You will like this especially when you useprograms that need an interpreter to run like Java, Python, .NET orEmacs-Lisp. It's also useful if you often run DOS executables underthe Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from<http://www.tldp.org/docs.html#howto>). Once you haveregistered such a binary class with the kernel, you can start one ofthose programs simply by typing in its name at a shell prompt; Linuxwill automatically feed it to the correct interpreter.You can do other nice things, too. Read the file<file:Documentation/binfmt_misc.txt> to learn how to use thisfeature, <file:Documentation/java.txt> for information about howto include Java support. and <file:Documentation/mono.txt> forinformation about how to include Mono-based .NET support.To use binfmt_misc, you will need to mount it:mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_miscYou may say M here for module support and later load the module whenyou have use for it; the module is called binfmt_misc. If youdon't know what to answer at this point, say Y.
