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.
