WCF service not returning JSONP which causes error in dojo app -

-

i have tried many demos , egs. , got advice here when having issues service requests. anyway using io.script.get data remote server , problem callback parameter either undefined or invalid label.

function searchgoogle() {     // node we'll stick text under.     var targetnode = dojo.byid("rules");     var jsonpargs = {   url: "http://localhost/wcfservices/wcfinstancerules2/service1.svc/retrievedata",      callbackparamname: "callback",        content: {             screenname: "dpjo"         },         load: function (data) {             // set data search viewbox in nicely formatted json             targetnode.innerhtml = "<pre>" + dojo.tojson(data, true) + "</pre>";         },         error: function (error) {             targetnode.innerhtml = "an unexpected error occurred: " + error;         }     };     dojo.io.script.get(jsonpargs); } dojo.ready(searchgoogle);

i see json response in fiddler , looks fine in browser error. frustrating because have been struggling cross domain issues. using .net 4.0 , no have explicitly define callback. tried manually editing json response adding callback name , wrapping json in callback name.

edit:

sample of data returned webservice:

{"rules":[{"value":"allstate"},{"value":"cidade de goa beach"},      {"value":"euro 2012"},{"value":"euro&2012"},      {"value":"euro2012"},  {"value":"european&championship"},      {"value":"holiday inn resort"},{"value":"holiday inn resort goa"},      {"value":"hotel goa"},{"value":"hyatt goa"},{"value":"i buy car}]}

its got problem on server. can try pointing @ known working service (like yahoo.com), quick test?

c++ - Troubles when compiling phash program -

-
here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
