c++ - MS VC++ 9 pcrecpp.lib linking error -

-

just built pcre-8.34 ms vc++ under windows x86, copied libs (pcrecpp.lib) , headers (pcrecpp.h, pcrecpparg.h, pcre_stringpiece.h) locations , wanted test simple code (that works under gnu linux c++) i'm getting linking errors:

#define pcre_static 1  #include <pcrecpp.h> #include <iostream>  #pragma comment(lib,"pcrecpp.lib")  using namespace std;  int main(void) {   pcrecpp::re regex("(hello)");   std::string strbase = "hello hello hello";    pcrecpp::stringpiece input(strbase);    std::string match;    int count = 0;   while (regex.findandconsume(&input, &match)) {     count++;     std::cout << count << " " << match << std::endl;   } }

building output:

any idea doing wrong? tried under vc++ 10, same errors. should include <pcre.h> , #pragma comment(lib,"pcre.lib") because if link occurs without error seem strange use c header , library in c++ code?

update:

i did this, , works, problem is: ok c++?

#define pcre_static 1  #include <pcrecpp.h> #include <iostream>  #pragma comment(lib,"pcrecpp.lib") #pragma comment(lib,"pcre.lib")  using namespace std;  int main(void) {   pcrecpp::re regex("(hello)");   std::string strbase = "hello hello hello";    pcrecpp::stringpiece input(strbase);    std::string match;    int count = 0;   while (regex.findandconsume(&input, &match)) {     count++;     std::cout << count << " " << match << std::endl;   } }

output:

you need link against "pcre.lib". if have @ "pcrecpp.h" source code see includes "pcre.h" uses "c part" of library.

python - Subclassed QStyledItemDelegate ignores Stylesheet -

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here

i using node.js script gather data stackoverflow. know responses gzipped, put code in should take care of that. script follows: var request = require('request'); var zlib = require('zlib'); function getstackoverflowresponse(url, callback){ request(url, {encoding: null}, function(err, response, body){ if(response.headers['content-encoding'] == 'gzip'){ zlib.gunzip(body, function(err, dezipped) { callback(dezipped); }); } else { callback(body); } }); } var url = "https://api.stackexchange.com/docs/questions#pagesize=2&order=desc&min=2014-01-04&max=2014-02-02&sort=activity&tagged=apigee&filter=default&site=stackoverflow&run=true"; getstackoverflowresponse(url, function(questions) { console.log(questions); }); instead of getting json output, i'm getting following response: buffer 0d 0a 0d 0a 0d 0a 0d 0a 3c 21 44 4f 43 54 59 50 45 20 48...
