1N/A!!!!!!! DO NOT EDIT THIS FILE !!!!!!!
1N/AThis file is built by metaconfig.
1N/AThis file contains a description of all the shell variables whose value is
1N/Adetermined by the Configure script. Variables intended for use in C
1N/Agenerates pod documentation for
Config.pm from this file--please try to keep
1N/Athe formatting regular.]
1N/A This variable defines the extension used for ordinary library files.
1N/A For unix, it is '.a'. The '.' is included. Other possible
1N/A values include '.lib'.
1N/A This variable defines the extension used for executable files.
1N/A DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'.
1N/A On operating systems which do not require a specific extension
1N/A for executable files, this variable is empty.
1N/A This variable defines the extension used for object files.
1N/A For unix, it is '.o'. The '.' is included. Other possible
1N/A values include '.obj'.
1N/A This variable is set to 'true' if AFS (Andrew File System) is used
1N/A on the system, 'false' otherwise. It is possible to override this
1N/A with a hint value or command line option, but you'd better know
1N/A This variable is by default set to '/afs'. In the unlikely case
1N/A this is not the correct root, it is possible to override this with
1N/A a hint value or command line option. This will be used in subsequent
1N/A tests for AFSness in the Perl configure and test process.
1N/A This variable holds the number of bytes required to align a
1N/A double-- or a long double when applicable. Usual values are
1N/A 2, 4 and 8. The default is eight, for safety.
1N/A This variable is set if the user needs to run ansi2knr.
1N/A Currently, this is not supported, so we just abort.
1N/A This variable contains the command which can be used to compute the
1N/A host name. The command is fully qualified by its absolute path, to make
1N/A it safe when used by a process with super-user privileges.
1N/A The three variables, api_revision, api_version, and
1N/A api_subversion, specify the version of the oldest perl binary
1N/A compatible with the present perl. In a full version string
1N/A such as '5.6.1', api_revision is the '5'.
1N/A Prior to 5.5.640, the format was a floating point number,
1N/A $sitelib/.. for older directories back to the limit specified
1N/A by these api_ variables. This is only useful if you have a
1N/A perl library directory tree structured like the default one.
1N/A See INSTALL for how this works. The versioned site_perl
1N/A directory was introduced in 5.005, so that is the lowest
1N/A possible value. The version list appropriate for the current
1N/A XXX To do: Since compatibility can depend on compile time
1N/A options (such as bincompat, longlong, etc.) it should
1N/A (perhaps) be set by Configure, but currently it isn't.
1N/A Perhaps what we ought to do is take the hard-wired value from
1N/A The three variables, api_revision, api_version, and
1N/A api_subversion, specify the version of the oldest perl binary
1N/A compatible with the present perl. In a full version string
1N/A such as '5.6.1', api_subversion is the '1'. See api_revision for
1N/A The three variables, api_revision, api_version, and
1N/A api_subversion, specify the version of the oldest perl binary
1N/A compatible with the present perl. In a full version string
1N/A such as '5.6.1', api_version is the '6'. See api_revision for
1N/A full details. As a special case, 5.5.0 is rendered in the
1N/A old-style as 5.005. (In the 5.005_0x maintenance series,
1N/A this was the only versioned directory in $sitelib.)
1N/A This variable combines api_revision, api_version, and
1N/A api_subversion in a format such as 5.6.1 (or 5_6_1) suitable
1N/A for use as a directory name. This is filesystem dependent.

1N/A This variable contains the compiler flags needed by large file builds
1N/A and added to ccflags by hints files.
1N/A This can set either by hints files or by Configure. If using
1N/A gcc, this is gcc, and if not, usually equal to cc, unimpressive, no?
1N/A Some platforms, however, make good use of this by storing the
1N/A flavor of the C compiler being used here. For example if using
1N/A the Sun WorkShop suite, ccname will be 'workshop'.

1N/A This variable describes the "style" of the perl installation.
1N/A This is intended to be useful for tools that need to
1N/A manipulate entire perl distributions. Perl itself doesn't use
1N/A this to find its libraries -- the library directories are
1N/A styles: "lib" and "
lib/perl5". The default library locations
1N/A is useful if $prefix is shared by many packages,
e.g. if
1N/A Unfortunately, while this "style" variable is used to set
1N/A defaults for all three directory hierarchies (core, vendor, and
1N/A site), there is no guarantee that the same style is actually
1N/A appropriate for all those directories. For example, $prefix
1N/A (Perhaps, in retrospect, the "lib" style should never have been
1N/A supported, but it did seem like a nice idea at the time.)
1N/A The situation is even less clear for tools such as MakeMaker
1N/A that can be used to install additional modules into
1N/A non-standard places. For example, if a user intends to install
1N/A a module into a private directory (perhaps by setting PREFIX on
1N/A assume that the Configure-time $installstyle setting will be
1N/A relevant for that PREFIX.
1N/A This may later be extended to include other information, so
1N/A be careful with pattern-matching on the results.

1N/A This variable contains any special flags that might need to be
1N/A passed to $ld to create a shared library suitable for dynamic
1N/A loading. It is up to the makefile to use it. For hpux, it
1N/A should be '-b'. For sunos 4.1, it is empty.

1N/A the user. It is up to the Makefile to use this.
1N/A This variable contains the loader flags needed by large file builds
1N/A and added to ldflags by hints files.
1N/A This variable holds the name of the shared library
1N/A search path, often LD_LIBRARY_PATH. To get an empty
1N/A string, the hints file must set this to 'none'.
1N/A This variable is used internally by Configure to determine the

1N/A REENTRANT_PROTO_T_ABC macros of
reentr.h if d_localtime_r
1N/A This variable contains a list of additional directories to be
1N/A searched by the compiler. The appropriate '-I' directives will
1N/A be added to ccflags. This is intended to simplify setting
1N/A local directories from the Configure command line.
1N/A It's not much, but it parallels the loclibpth stuff in
libpth.U. 1N/A This variable holds the paths (space-separated) used to find local
1N/A libraries. It is prepended to libpth, and is intended to be easily
1N/A set from the command line.

1N/A Possible values are "BSD 4.3" and "System V".
1N/A This variable can be used to establish a fallthrough for the cases
1N/A where nm fails to find a symbol. If usenm is false or usenm is true
1N/A and mistrustnm is false, this variable has no effect. If usenm is true
1N/A and mistrustnm is "compile", a test program will be compiled to try to
1N/A find any symbol that can't be located via nm lookup. If mistrustnm is
1N/A "run", the test program will be run as well as being compiled.

1N/A The value is a plain '' and is not useful.
1N/A This variable holds the architecture name computed by Configure in
1N/A a previous run. It is not intended to be perused by any user and

1N/A The output of 'uname -a' if available, otherwise the hostname. On Xenix,
1N/A pseudo variables assignments in the output are stripped, thank you. The
1N/A whole thing is then lower-cased.
1N/A This variable contains the '-n' flag if that is what causes the echo
1N/A command to suppress newline. Otherwise it is null. Correct usage is
1N/A $echo $n "prompt for a question: $c".
1N/A This symbol, if defined, indicates that the system stores
1N/A the variable argument list datatype, va_list, in a format
1N/A that cannot be copied by simple assignment, so that some
1N/A other means must be used when copying is required.
1N/A As such systems vary in their provision (or non-provision)
1N/A of copying mechanisms,
handy.h defines a platform-
1N/A independent macro, Perl_va_copy(src, dst), to do the job.
1N/A This variable holds the type used for the 2nd argument to

1N/A This variable holds the options that may be necessary for nm
1N/A to work on a shared library but that can not be used on an
1N/A archive library. Currently, this is only used by Linux, where
1N/A nm --dynamic is *required* to get symbols from an ELF library which
1N/A has been stripped, but nm --dynamic is *fatal* on an archive library.
1N/A Maybe Linux should just always set usenm=false.
1N/A This variable holds a list of all non-xs extensions included
1N/A in the package. All of them will be built.

1N/A This variable bears the symbol value to be used during open() or fcntl()
1N/A to turn on non-blocking I/O for a file descriptor. If you wish to switch

1N/A but that is only supported by some devices.
1N/A This is an old synonym for _o.
1N/A This variable defines the constant to use for creating joinable
1N/A PTHREAD_CREATE_JOINABLE. If used, possible values are
1N/A PTHREAD_CREATE_UNDETACHED and __UNDETACHED.
1N/A It is up to the Makefile to use it.
1N/A This variable is "true" if the components of libraries must be ordered
1N/A (with `lorder $* | tsort`) before placing them in an archive. Set to
1N/A "false" if ranlib or ar can generate random libraries.
1N/A This variable contains the operating system name (
e.g. sunos,
1N/A solaris, hpux, etc.). It can be useful later on for setting
1N/A defaults. Any spaces are replaced with underscores. It is set
1N/A to a null string if we can't figure it out.
1N/A This variable contains the operating system version (
e.g. 1N/A 4.1.3, 5.2, etc.). It is primarily used for helping select
1N/A an appropriate hints file, but might be useful elsewhere for
1N/A setting defaults. It is set to '' if we can't figure it out.
1N/A We try to be flexible about how much of the version number
1N/A to keep,
e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
1N/A same for this package, hints files might just be os_4.0 or
1N/A os_4.1, etc., not keeping separate files for each little release.
1N/A This variable contains a colon-separated set of paths for the perl
1N/A binary to search for additional library files or modules.
1N/A These directories will be tacked to the end of @INC.

1N/A The value is a plain '' and is not useful.
1N/A This is the Perl patch level, a numeric change identifier,
1N/A as defined by whichever source code maintenance system
1N/A is used to maintain the patches; currently Perforce.
1N/A It does not correlate with the Perl version numbers or
1N/A the maintenance versus development dichotomy except
1N/A by also being increasing.
1N/A In a Perl version number such as 5.6.2, this is the 5.

1N/A shell scripts and in the "eval 'exec'" idiom. This variable is
1N/A not necessarily the pathname of the file containing the perl
1N/A interpreter; you must append the executable extension (_exe) if
1N/A it is not already present. Note that Perl code that runs during

1N/A may not have been installed, or even if installed, may be a
1N/A different version of Perl.

1N/A needed to generate random libraries. Set to ":" if ar can generate
1N/A random libraries or if random libraries are not supported
1N/A This variable holds the return code from read() when no data is
1N/A present. It should be -1, but some systems return 0 when O_NDELAY is
1N/A used, which is a shame because you cannot make the difference between
1N/A no data and an EOF.. Sigh!
1N/A This variable encodes the prototype of readdir64_r.

1N/A of the current thread.
1N/A This variable holds the name of the directory in which the user wants
1N/A to put publicly scripts for the package in question. It is either

1N/A on a particular system.
1N/A This variable conditionally defines the USE_REENTRANT_API symbol,
1N/A which indicates that the thread code may try to use the various
1N/A _r versions of library functions. This is only potentially
1N/A meaningful if usethreads is set and is very experimental, it is
1N/A not even prompted for.
1N/A This variable is set to true when the user agrees to use sfio.
1N/A It is set to false when sfio is not available or when the user
1N/A explicitely requests not to use sfio. It is here primarily so
1N/A that command-line settings can override the auto-detection of
1N/A d_sfio without running into a "WHOA THERE".
1N/A This variable is set to 'true' if the user wishes
1N/A to build a shared libperl, and 'false' otherwise.
1N/A This variable conditionally defines the USE_SOCKS symbol,
1N/A and indicates that Perl should be built to use SOCKS.
