bincompat5005 (bincompat5005.U):
- This variable contains y if Perl 5.006 should be binary-compatible
- with Perl 5.005.
+ This variable contains y if this version of Perl should be
+ binary-compatible with Perl 5.005.
binexp (bin.U):
This is the same as the bin variable, but is filename expanded at
ccsymbols (Cppsym.U):
The variable contains the symbols defined by the C compiler alone.
+ The symbols defined by cpp or by cc when it calls cpp are not in
+ this list, see cppsymbols and cppccsymbols.
The list is a space-separated list of symbol=value tokens.
cf_by (cf_who.U):
used by the C preprocessor.
cppccsymbols (Cppsym.U):
- The variable contains the symbols defined by both
- the bare C compiler and during a compilation that
- includes stdio.h.
+ The variable contains the symbols defined by the C compiler
+ when it calls cpp. The symbols defined by the cc alone or cpp
+ alone are not in this list, see ccsymbols and cppsymbols.
The list is a space-separated list of symbol=value tokens.
cppflags (ccflags.U):
preprocessor symbols.
cppsymbols (Cppsym.U):
- The variable contains the symbols during a compilation
- that includes stdio.h.
+ The variable contains the symbols defined by the C preprocessor
+ alone. The symbols defined by cc or by cc when it calls cpp are
+ not in this list, see ccsymbols and cppccsymbols.
The list is a space-separated list of symbol=value tokens.
crosscompile (crosscompile.U):
d_bincompat5005 (bincompat5005.U):
This variable conditionally defines BINCOMPAT5005 so that embed.h
- can take special action if Perl 5.006 should be binary-compatible
- with Perl 5.005. This is impossible for builds that use features
- like threads and multiplicity it is always $undef for those versions.
+ can take special action if this version of Perl should be
+ binary-compatible with Perl 5.005. This is impossible for builds
+ that use features like threads and multiplicity it is always $undef
+ for those versions.
d_bsd (Guess.U):
This symbol conditionally defines the symbol BSD when running on a
d_fpos64_t (d_fpos64_t.U):
This symbol will be defined if the C compiler supports fpos64_t.
+d_frexpl (d_frexpl.U):
+ This variable conditionally defines the HAS_FREXPL symbol, which
+ indicates to the C program that the frexpl() routine is available.
+
d_fs_data_s (d_fs_data_s.U):
This variable conditionally defines the HAS_STRUCT_FS_DATA symbol,
which indicates that the struct fs_data is supported.
This variable conditionally defines the HAS_ISASCII constant,
which indicates to the C program that isascii() is available.
+d_isnan (d_isnan.U):
+ This variable conditionally defines the HAS_ISNAN symbol, which
+ indicates to the C program that the isnan() routine is available.
+
+d_isnanl (d_isnanl.U):
+ This variable conditionally defines the HAS_ISNANL symbol, which
+ indicates to the C program that the isnanl() routine is available.
+
d_killpg (d_killpg.U):
This variable conditionally defines the HAS_KILLPG symbol, which
indicates to the C program that the killpg() routine is available
This variable conditionally defines HAS_MMAP if mmap() is
available to map a file into memory.
+d_modfl (d_modfl.U):
+ This variable conditionally defines the HAS_MODFL symbol, which
+ indicates to the C program that the modfl() routine is available.
+
d_mprotect (d_mprotect.U):
This variable conditionally defines HAS_MPROTECT if mprotect() is
available to modify the access protection of a memory mapped file.
indicates to the C program that the pause() routine is available
to suspend a process until a signal is received.
+d_perl_otherlibdirs (otherlibdirs.U):
+ This variable conditionally defines PERL_OTHERLIBDIRS, which
+ contains a colon-separated set of paths for the perl binary to
+ include in @INC. See also otherlibdirs.
+
d_phostname (d_gethname.U):
This variable conditionally defines the HAS_PHOSTNAME symbol, which
contains the shell command which, when fed to popen(), may be
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.
+otherlibdirs (otherlibdirs.U):
+ This variable contains a colon-separated set of paths for the perl
+ binary to search for additional library files or modules.
+ These directories will be tacked to the end of @INC.
+ Perl will automatically search below each path for version-
+ and architecture-specific directories. See inc_version_list
+ for more details.
+ A value of ' ' means 'none' and is used to preserve this value
+ for the next run through Configure.
+
package (package.U):
This variable contains the name of the package being constructed.
It is primarily intended for the use of later Configure units.
This variable holds the full absolute path of the directory below
which the user will install add-on packages. Derived from siteprefix.
+sizesize (sizesize.U):
+ This variable contains the size of a sizetype in bytes.
+
sizetype (sizetype.U):
This variable defines sizetype to be something like size_t,
unsigned long, or whatever type is used to declare length
