Prototype mismatch: sub main::to_json: none vs ($@) at mymodule.pm line 6. I guess this is because in my module I'm importing the perl JSON module. Everything seems to perform fine, but I'm wondering what this error/warning is all about? I can't seem to find anything about it online. perl module share|improve this question asked Apr 2 '13 at 17:10 pepper 68811121 1 Do you by "importing the JSON module" mean "pre-declaring the subroutines from_json and to_json"? With something like sub from_json;? –TLP Apr 2 '13 at 17:20 no I mean I use the header "use JSON;" in my module, which is a file named mymodule.pm (containing a package of the same name). Then from my application file I import that module file with "use mymodule;". –pepper Apr 2 '13 at 18:02 1 Don't really understand why this question has been downvoted. Seems perfectly reasonable to me. –pepper Apr 2 '13 at 18:04 1 did you use from_json and to_json passing 1 or 2 scalar arguments? –Miguel Prz Apr 2 '13 at 18:15 Sounds like a reasonable guess, but I answered my own question below. –pepper Apr 2 '13 at 18:19 add a comment| 4 Answers 4 active oldest votes up vote 9 down vote accepted Another situation where this arises is when some other module you have loaded defines a from_json/t

Re: Prototype mismatch: sub main::trim: none vs ($) at by davido (Archbishop) on Mar 04, 2011 at 09:09UTC http://stackoverflow.com/questions/15770114/prototype-mismatch-error-perl The part after "at" probably lists a line number from your code, or from the module you're using. But you showed no code in your post. I think we're going to need more information than you've provided if we are to help you with this issue. Please post a minimally constructed executable snippet of code that replicates your error. Do you mean LWP, instead of LPW? I did a search for LPW and http://www.perlmonks.org/?node_id=891394 Perl, and came up with the same blank that my mind produced when I read your question.

Exactly what the message says, a prototype mismatch $ perl -Mdiagnostics -e " sub trim(); sub trim($){warn@_} ; " Prototype mismatch: sub main::trim () vs ($) at -e line 1 (#1) (S prototype) The subroutine being declared or defined had previou +sly been declared or defined with a different function prototype.

[download] There's no problem if the declaration has no prototype, so this isn't the cause of your problem. An implicit declaration of a function and its definition don't match: >perl -we"trim('abc'); sub trim($) {}" main::trim() called too early to chec
Customer Service Bugs Tips Prototype mismatch: sub main::head ($) vs none By Wick On July 9, 2009 In bugs, perl Turns out that when you use the LWP::Simple & CGI modules together in a http://blog.netscraps.com/bugs/prototype-mismatch-sub-mainhead-vs-none.html Perl script, each has a conflicting head() function that throws that error. Who http://www.perlmonks.org/bare/?node_id=200972 knew? Everyone who took the time to read the CAVEAT note at the end of the LWP::Simple docs, apparently: Note that if you are using both LWP::Simple and the very popular CGI.pm module, you may be importing a head function from each module, producing a warning like "Prototype mismatch: sub perl error main::head ($) vs none". Get around this problem by just not importing LWP::Simple's head function, like so: use LWP::Simple qw(!head); use CGI qw(:standard); # then only CGI.pm defines a head() Then if you do need LWP::Simple's head function, you can just call it as LWP::Simple::head($url).
