c - Undefined reference to `gdk_color_parse' -

-

i'm using gtk + 3.0 lib, , i'm getting errors:

undefined reference `gdk_color_parse'

my source code:

int connectps3(gtkwidget *button) {     hinstance   hlib;     hlib = loadlibrary("ccapi.dll");      gchar   *ip;     ip = "192.168.0.40";       __cconnect v_connectps3 = getprocaddress(hlib, "ccapiconnectconsole");     __cnotify v_notifyps3 = getprocaddress(hlib, "ccapivshnotify");      gdkcolor    color;      if (v_connectps3(ip) == 0)     {         v_notifyps3(trophy2, "connected ps3");         gtk_button_set_label(gtk_button(button), "connected");         gdk_color_parse("green", &color);         gtk_widget_modify_bg(button, gtk_state_normal, &color);     }     else     {         gtk_button_set_label(gtk_button(button), "can't connect ip address");         gdk_color_parse("red", &color);         gtk_widget_modify_bg(button, gtk_state_normal, &color);     }      return (0); }

so if can tell me why i'm getting that, i'll thankful.

i have no linker settings.

as per this previous answer, looks there change required in compilation statement.

however, in general, please check below points,

  1. all libraries used (required) should linked with.
  2. the order of appearance of libraries matter, re-check order in regards dependency.

c# - Where does the .ToList() go in LINQ query result -

-
when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
