(X) You can't allocate more than 64K on an MS-DOS machine.
-=item '!' allowed only after types %s
+=item '%c' allowed only after types %s
-(F) The '!' is allowed in pack() or unpack() only after certain types.
-See L<perlfunc/pack>.
+(F) The modifiers '!', '<' and '>' are allowed in pack() or unpack() only
+after certain types. See L<perlfunc/pack>.
=item Ambiguous call resolved as CORE::%s(), qualify as such or use &
point. For example, it'd be kind of silly to put a B<-x> on the #!
line.
+=item Can't %s %s-endian %ss on this platform
+
+(F) Your platform's byte-order is neither big-endian nor little-endian,
+or it has a very strange pointer size. Packing and unpacking big- or
+little-endian floating point values and pointers may not be possible.
+See L<perlfunc/pack>.
+
=item Can't exec "%s": %s
(W exec) A system(), exec(), or piped open call could not execute the
inner curlies will be considered a block that loops once. See
L<perlfunc/last>.
+=item Can't load '%s' for module %s
+
+(F) The module you tried to load failed to load a dynamic extension. This
+may either mean that you upgraded your version of perl to one that is
+incompatible with your old dynamic extensions (which is known to happen
+between major versions of perl), or (more likely) that your dynamic
+extension was built against an older version of the library that is
+installed on your system. You may need to rebuild your old dynamic
+extensions.
+
=item Can't localize lexical variable %s
(F) You used local on a variable name that was previously declared as a
are a misprint in a function/method name or a failure to C<AutoSplit>
the file, say, by doing C<make install>.
+=item Can't locate loadable object for module %s in @INC
+
+(F) The module you loaded is trying to load an external library, like
+for example, C<foo.so> or C<bar.dll>, but the L<DynaLoader> module was
+unable to locate this library. See L<DynaLoader>.
+
=item Can't locate object method "%s" via package "%s"
(F) You called a method correctly, and it correctly indicated a package
(F) The script you specified can't be opened for the indicated reason.
-=item Can't provide tied hash usage; use keys(%hash) to test if empty
-
-(F) When a hash is evaluated in scalar context, bucket usage is
-returned if the hash is populated, and false is returned if the hash
-is empty. Bucket usage is not currently available for tied hashes.
-To test if a hash is empty or populated, use keys(%hash) in scalar
-context instead.
+If you're debugging a script that uses #!, and normally relies on the
+shell's $PATH search, the -S option causes perl to do that search, so
+you don't have to type the path or C<`which $scriptname`>.
=item Can't read CRTL environ
Errno.pm module. The Errno module is expected to tie the %! hash to
provide symbolic names for C<$!> errno values.
+=item Can't use both '<' and '>' after type '%c' in %s
+
+(F) A type cannot be forced to have both big-endian and little-endian
+byte-order at the same time, so this combination of modifiers is not
+allowed. See L<perlfunc/pack>.
+
=item Can't use %s for loop variable
(F) Only a simple scalar variable may be used as a loop variable on a
have variables in your program that looked like magical variables but
weren't.
+=item Can't use '%c' in a group with different byte-order in %s
+
+(F) You attempted to force a different byte-order on a type
+that is already inside a group with a byte-order modifier.
+For example you cannot force little-endianness on a type that
+is inside a big-endian group.
+
=item Can't use "my %s" in sort comparison
(F) The global variables $a and $b are reserved for sort comparisons.
long for Perl to handle. You have to be seriously twisted to write code
that triggers this error.
+=item Deprecated use of my() in false conditional
+
+(D deprecated) You used a declaration similar to C<my $x if 0>.
+There has been a long-standing bug in Perl that causes a lexical variable
+not to be cleared at scope exit when its declaration includes a false
+conditional. Some people have exploited this bug to achieve a kind of
+static variable. Since we intend to fix this bug, we don't want people
+relying on this behavior. You can achieve a similar static effect by
+declaring the variable in a separate block outside the function, eg
+
+ sub f { my $x if 0; return $x++ }
+
+becomes
+
+ { my $x; sub f { return $x++ } }
+
+=item DESTROY created new reference to dead object '%s'
+
+(F) A DESTROY() method created a new reference to the object which is
+just being DESTROYed. Perl is confused, and prefers to abort rather than
+to create a dangling reference.
+
=item Did not produce a valid header
See Server error.
=item (Do you need to predeclare %s?)
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". It often means a subroutine or module
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". It often means a subroutine or module
name is being referenced that hasn't been declared yet. This may be
because of ordering problems in your file, or because of a missing
"sub", "package", "require", or "use" statement. If you're referencing
(S malloc) An internal routine called free() on something that had
already been freed.
+=item Duplicate modifier '%c' after '%c' in %s
+
+(W) You have applied the same modifier more than once after a type
+in a pack template. See L<perlfunc/pack>.
+
=item elseif should be elsif
-(S) There is no keyword "elseif" in Perl because Larry thinks it's ugly.
-Your code will be interpreted as an attempt to call a method named
+(S syntax) There is no keyword "elseif" in Perl because Larry thinks it's
+ugly. Your code will be interpreted as an attempt to call a method named
"elseif" for the class returned by the following block. This is
unlikely to be what you want.
=item %s found where operator expected
-(S) The Perl lexer knows whether to expect a term or an operator. If it
-sees what it knows to be a term when it was expecting to see an
+(S syntax) The Perl lexer knows whether to expect a term or an operator.
+If it sees what it knows to be a term when it was expecting to see an
operator, it gives you this warning. Usually it indicates that an
operator or delimiter was omitted, such as a semicolon.
(F) When using the C<sub> keyword to construct an anonymous subroutine,
you must always specify a block of code. See L<perlsub>.
+=item Illegal declaration of subroutine %s
+
+(F) A subroutine was not declared correctly. See L<perlsub>.
+
=item Illegal division by zero
(F) You tried to divide a number by 0. Either something was wrong in

-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". Often the missing operator is a comma.
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". Often the missing operator is a comma.
=item Missing right brace on %s
=item (Missing semicolon on previous line?)
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". Don't automatically put a semicolon on
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". Don't automatically put a semicolon on
the previous line just because you saw this message.
=item Modification of a read-only value attempted
(S internal) The symbol in question was declared but somehow went out of
scope before it could possibly have been used.
-=item Newline in left-justified string for %s
-
-(W printf) There is a newline in a string to be left justified by
-C<printf> or C<sprintf>.
-
-The padding spaces will appear after the newline, which is probably not
-what you wanted. Usually you should remove the newline from the string
-and put formatting characters in the C<sprintf> format.
-
=item No %s allowed while running setuid
(F) Certain operations are deemed to be too insecure for a setuid or
the current limits and change them, and in ksh/bash/zsh use C<ulimit -a>
and C<ulimit -d n>, respectively.
+=item Out of memory during %s extend
+
+(X) An attempt was made to extend an array, a list, or a string beyond
+the largest possible memory allocation.
+
=item Out of memory during "large" request for %s
(F) The malloc() function returned 0, indicating there was insufficient
(P) The compiler is screwed up with respect to the map() function.
+=item panic: memory wrap
+
+(P) Something tried to allocate more memory than possible.
+
=item panic: null array
(P) One of the internal array routines was passed a null AV pointer.
"Can't locate object method \"%s\" via package \"%s\"". It often means
that a method requires a package that has not been loaded.
+=item Perl_my_%s() not available
+
+(F) Your platform has very uncommon byte-order and integer size,
+so it was not possible to set up some or all fixed-width byte-order
+conversion functions. This is only a problem when you're using the
+'<' or '>' modifiers in (un)pack templates. See L<perlfunc/pack>.
+
=item Perl %s required--this is only version %s, stopped
(F) The module in question uses features of a version of Perl more
(P) A "can't happen" error, because safemalloc() should have caught it
earlier.
+=item Repeated format line will never terminate (~~ and @# incompatible)
+
+(F) Your format containes the ~~ repeat-until-blank sequence and a
+numeric field that will never go blank so that the repetition never
+terminates. You might use ^# instead. See L<perlform>.
+
=item Reversed %s= operator
(W syntax) You wrote your assignment operator backwards. The = must
(F) You don't have System V shared memory IPC on your system.
+=item !=~ should be !~
+
+(W syntax) The non-matching operator is !~, not !=~. !=~ will be
+interpreted as the != (numeric not equal) and ~ (1's complement)
+operators: probably not what you intended.
+
=item <> should be quotes
(F) You wrote C<< require <file> >> when you should have written
past the symlink to get to the real file. Use an actual filename
instead.
+=item The 'unique' attribute may only be applied to 'our' variables
+
+(F) Currently this attribute is not supported on C<my> or C<sub>
+declarations. See L<perlfunc/our>.

=item This Perl can't reset CRTL environ elements (%s)
=item This Perl can't set CRTL environ elements (%s=%s)
(F) The entry point function of threads->create() failed for some reason.
-=item Tied variable freed while still in use
-
-(F) An access method for a tied variable (e.g. FETCH) did something to
-free the variable. Since continuing the current operation is likely
-to result in a coredump, Perl is bailing out instead.
-
=item times not implemented
(F) Your version of the C library apparently doesn't do times(). I
suspect you're not running on Unix.
+=item "-T" is on the #! line, it must also be used on the command line
+
+(X) The #! line (or local equivalent) in a Perl script contains the
+B<-T> option, but Perl was not invoked with B<-T> in its command line.
+This is an error because, by the time Perl discovers a B<-T> in a
+script, it's too late to properly taint everything from the environment.
+So Perl gives up.
+
+If the Perl script is being executed as a command using the #!
+mechanism (or its local equivalent), this error can usually be fixed by
+editing the #! line so that the B<-T> option is a part of Perl's first
+argument: e.g. change C<perl -n -T> to C<perl -T -n>.
+
+If the Perl script is being executed as C<perl scriptname>, then the
+B<-T> option must appear on the command line: C<perl -T scriptname>.
+
=item To%s: illegal mapping '%s'
(F) You tried to define a customized To-mapping for lc(), lcfirst,
B<-M> or B<-m> option. This is an error because B<-M> and B<-m> options
are not intended for use inside scripts. Use the C<use> pragma instead.
