This file contains a description of all the shell variables whose value is
|
|
determined by the Configure script. Variables intended for use in C
|
|
programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm'
|
|
generates pod documentation for Config.pm from this file--please try to keep
|
|
the formatting regular.]
|
|
|
|
Mcc (Loc.U):
|
|
This variable is used internally by Configure to determine the
|
|
full pathname (if any) of the Mcc program. After Configure runs,
|
|
the value is reset to a plain "Mcc" and is not useful.
|
|
|
|
_a (Unix.U):
|
|
This variable defines the extension used for ordinary libraries.
|
|
For unix, it is '.a'. The '.' is included. Other possible
|
|
values include '.lib'.
|
|
|
|
_exe (Unix.U):
|
|
This variable defines the extension used for executable files.
|
|
For unix it is empty. Other possible values include '.exe'.
|
|
|
|
_o (Unix.U):
|
|
This variable defines the extension used for object files.
|
|
For unix, it is '.o'. The '.' is included. Other possible
|
|
values include '.obj'.
|
|
|
|
afs (afs.U):
|
|
This variable is set to 'true' if AFS (Andrew File System) is used
|
|
on the system, 'false' otherwise. It is possible to override this
|
|
with a hint value or command line option, but you'd better know
|
|
what you are doing.
|
|
|
|
alignbytes (alignbytes.U):
|
|
This variable holds the number of bytes required to align a
|
|
double. Usual values are 2, 4 and 8.
|
|
|
|
ansi2knr (ansi2knr.U):
|
|
This variable is set if the user needs to run ansi2knr.

|
|
|
aphostname (d_gethname.U):
|
|
Thie variable contains the command which can be used to compute the
|
|
host name. The command is fully qualified by its absolute path, to make

|
it safe when used by a process with super-user privileges.
|
|
|
|
apiversion (patchlevel.U):
|
|
This is a number which identifies the lowest version of perl
|
|
to have an API (for XS extensions) compatible with the present
|
|
version. For example, for 5.005_01, the apiversion should be
|
|
5.005, since 5.005_01 should be binary compatible with 5.005.
|
|
This should probably be incremented manually somehow, perhaps
|
|
from patchlevel.h. For now, we'll guess maintenance subversions
|
|
will retain binary compatibility.
|
|
|
|
ar (Loc.U):
|
|

|
|
full pathname (if any) of the ar program. After Configure runs,

|
|
in with the program on this architecture. On unix, it is usually
|
|
empty. It is typically used to include emulations of unix calls
|
|
or other facilities. For perl on OS/2, for example, this would
|
|
include os2/os2.obj.
|
|
|
|
awk (Loc.U):
|
|

|
'set' value (from a previous config.sh or Configure '-D' option)
|
|
from an uncomputed value.

|
n (n.U):
|
|
This variable contains the '-n' flag if that is what causes the echo
|

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

"false" if ranlib or ar can generate random libraries.
|
|
|
|
osname (Oldconfig.U):
|
|
This variable contains the operating system name (e.g. sunos,

We try to be flexible about how much of the version number
|
|
to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the
|
|
same for this package, hints files might just be os_4.0 or
|
|
os_4.1, etc., not keeping separate files for each little release.

|
there already.
|

|
|
executables go in /usr/local/bin, library stuff in /usr/local/lib,
|
|
man pages in /usr/local/man, etc. It is only used to set defaults
|
|
for things in bin.U, mansrc.U, privlib.U, or scriptdir.U.
|
|
|
|
prefixexp (prefix.U):
|
|
This variable holds the full absolute path of the directory below

|
|
which is the name of the private library for this package. It may
|
|
have a ~ on the front. It is up to the makefile to eventually create
|
|
this directory while performing installation (with ~ substitution).
|
|
|
|
privlibexp (privlib.U):
|
|
This variable is the ~name expanded version of privlib, so that you

|
|
|
|
rd_nodata (nblock_io.U):
|
|
This variable holds the return code from read() when no data is
|
|
present. It should be -1, but some systems return 0 when O_NDELAY is

used, which is a shame because you cannot make the difference between
|
|
no data and an EOF.. Sigh!
|
|
|
|
rm (Loc.U):
|
|
This variable is used internally by Configure to determine the
|
|

scriptdir (scriptdir.U):
|
|
This variable holds the name of the directory in which the user wants
|
|
to put publicly scripts for the package in question. It is either
|
|
the same directory as for binaries, or a special one that can be

|
|
must be prepared to deal with ~name expansion.
|
|
|
|
scriptdirexp (scriptdir.U):

|
at configuration time, for programs not wanting to bother with it.
|
|
|
|
sed (Loc.U):

|
|
That is, if you do select(n, ...), how many bits at least will be
|
|
cleared in the masks if some activity is detected. Usually this

|
|
|
|
sh (sh.U):
|
|
This variable contains the full pathname of the shell used
|

|
/bin/sh, though it's possible that some systems will have /bin/ksh,
|
|
/bin/pdksh, /bin/ash, /bin/bash, or even something such as
|
|
D:/bin/sh.exe.
|
|
This unit comes before Options.U, so you can't set sh with a '-D'
|
|
option, though you can override this (and startsh)
|
|
with '-O -Dsh=/bin/whatever -Dstartsh=whatever'
|
|
|

This variable contains the value of the SHORTSIZE symbol which
|
|
indicates to the C program how many bytes there are in a short.
|
|
|
|
shrpenv (libperl.U):
|
|
If the user builds a shared libperl.so, then we need to tell the
|
|
'perl' executable where it will be able to find the installed libperl.so.
|
|
One way to do this on some systems is to set the environment variable
|
|
LD_RUN_PATH to the directory that will be the final location of the
|
|
shared libperl.so. The makefile can use this with something like
|
|
$shrpenv $(CC) -o perl perlmain.o $libperl $libs
|
|
Typical values are
|
|
shrpenv="env LD_RUN_PATH=$archlibexp/CORE"
|
|
or
|
|
shrpenv=''
|
|
See the main perl Makefile.SH for actual working usage.
|
|
Alternatively, we might be able to use a command line option such
|
|
as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath
|
|
$archlibexp/CORE (Linux).
|
|

|
|
is removed. See sig_num.
|
|
|
|
sig_num (sig_name.U):
|
|
This variable holds the signal numbers, comma separated. A 0 is
|
|
prepended to the list (corresponding to the fake SIGZERO), and

the value of the signal listed in the same place within the
|
|
sig_name list.
|
|
|
|
sig_num_init (sig_name.U):
|

|
|
This variable is set to true when the user agrees to use sfio.
|
|
It is set to false when sfio is not available or when the user

d_sfio without running into a "WHOA THERE".
|
|
|
|
useshrplib (libperl.U):

|
baserev, patchlevel, and subversion to get the full
|
|
version number, including any possible subversions. Care
|
|
is taken to use the C locale in order to get something
|
