user interface - Using FLTK with Dev-C++ -


i have been working on several programming languages java , python , came c++. want build gui program , suggested use fltk, claimed lightweight , user-friendly. however, told install series of third-party tools, while still can't figure out how create simple gui application.

i first told install enormous ide dev-c++ , download fltk source code (obtained here). "tutorials" on internet suggested me install fltk package (obtained here), while couldn't find tutorials or documentations how "import" library (i mean, specifying classpath , import classes in java). tried copy fltk source code dev-c++ folder dev-cpp\mingw64\x86_64-w64-mingw32\include, created fltk project , started compiling following code (auto-generated):

/* ** copyright © yyyy name ** ** program free software; can redistribute and/or modify ** under terms of gnu general public license published ** free software foundation; either version 2 of license, or ** (at option) later version. ** ** program distributed in hope useful, ** without warranty; without implied warranty of ** merchantability or fitness particular purpose. see ** gnu library general public license more details. ** ** should have received copy of gnu general public license ** along program; if not, write free software ** foundation, inc., 59 temple place - suite 330, boston, ma 02111-1307, usa. */  /**    @file main.cpp    @author name    @date yyyy-mm-dd    @version 0.01 */  #include <fl/fl.h> #include <fl/fl_window.h> #include <fl/fl_box.h>  int main(int argc, char ** argv) {     fl_window *window;     fl_box *box;      window = new fl_window(300, 180);     box = new fl_box(20, 40, 260, 100, "hello world!");      box->box(fl_up_box);     box->labelsize(36);     box->labelfont(fl_bold+fl_italic);     box->labeltype(fl_shadow_label);     window->end();     window->show(argc, argv);      return(fl::run()); }

instead of successful compilation, appears error message: (copied compile log)

i don't know how should proceed. seems me c++ support-lacking , undeveloped programming language sucks. please me, or @ least, give me hints, create simple gui, , correct misconceptions if there any. in advance.

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
