I would assume that you are mixing versions of `strict.pm` and versions of Perl.exe that were not distributed together. Stop doing that. The line in question is `my (undef, $f, $l) = caller;` [download] ... which works under 5.12 and (obviously) 5.14. You can go and look at `strict.pm` to see what version of the file you have, and then run `perl -v` to see what version of Perl you are running, and then at perlrun to investigate why your version of Perl is picking up files from a version of Perl that it should not see.

Thanks a lot, I had an old perl version on PC and the newer version in bin directory. I cannot change path and settings on my notebook. The Version did in deed not match the strict.pm. Sorry I am an bloody greenhorn	[reply]
Re^3: strict.pm error by Corion (Patriarch) on Dec 22, 2011 at 13:42 UTC
You can indeed change the path and the environment before invoking Perl. For example, I use a batch file like this to set up the environment for every version of Perl I use: `@echo off set base=%~dp0 path %BASE%perl\bin;%BASE%c\bin;%BASE%perl\site\bin;%PATH%` [download] This file lives in the base directory of every Perl installation I have, like `C:\strawberry-5.10` and `C:\strawberry` (which is currently 5.12). If I want to switch to a particular Perl, I invoke the batch file in the appropriate directory and thus switch the Perl for that shell window.	[reply] [d/l] [select]

You probably have a statement in your code like: `my ($x, undef, $y) = something()...;` [download] This should work in most versions of perl after 5.6. What version of perl are you using (run "perl -v"). A workaround would be to change the "undef" to a name like "$unused_1". "XML is like violence: if it doesn't solve your problem, use more."

This was exactly the problem. I was running an older version of perl. Thanks a lot for your help	[reply]

My guess would be that your perl (the one that's actually loading `strict.pm`) is too old for the syntax `my (undef, $f, $l) = caller; ^^^^^` [download]	[reply] [d/l] [select]

Can't declare %s in "%s" (F) Only scalar, array, and hash variables may be declared as "my", "our" or "state" variables. They must have ordinary identifiers as names. See perlintro, diagnostics	[reply]
