glib

问题 I'm using GDBus (via Glib) and I have code like: method_call_message = g_dbus_message_new_method_call(owner, OBJECT_PATH, INTERFACE_NAME, "get_snmpv2_mib"); GVariant *gv = g_variant_new("(sissi)", ip, port, mib, variable, instance); g_dbus_message_set_body(method_call_message, gv); I assume method_call_message is now a container for gv . Before exiting I call: g_object_unref(method_call_message); I assume this will then schedule BOTH method_call_message and gv for GC? When is GC done? I

问题 I have installed meld 3.14.2, at last (on NFS share in Redhat 6.3 server), after nearly 40 hours of efforts , installing each and every dependency and at last seems to be successful. But one finale error needs to be solved: (meld:20703): GLib-GIO-ERROR **: No GSettings schemas are installed on the system Trace/breakpoint trap (core dumped) There was answer here: GLib-GIO-ERROR**: No GSettings schemas are installed on the system I am not aware of these jargons before. So, please explain in

问题 I'm trying to get options parsing using OptionContext to work. My code so far: public class Options : GLib.Object { public string option_output = ""; public Options () { } public void parse (string args[]) throws OptionError { // string option_output; const OptionEntry[] options = { { "output", 'o', 0, OptionArg.FILENAME, ref option_output, "file name for encoded output (required);", "FILE" }, {null} }; var opt_context = new OptionContext ("- vpng2theora"); opt_context.set_help_enabled (true)

问题 I was trying to execute a shell command (ls /home) and trying to read the output where actually is the problem with this program? Here is the program. #include <stdio.h> #include <glib.h> #include <stdlib.h> #include <signal.h> typedef struct{ int std_in; int std_out; int std_err; }child_fds; gboolean cb_stdout(GIOChannel* channel, GIOCondition condition, gpointer data){ if(condition & G_IO_ERR ){ return TRUE; } if(condition & G_IO_HUP ){ return FALSE; } gsize actually_read; gchar* shell_out

问题 I would like to interface an garbage collected language (specifically, it's using the venerable Boehm libgc) to the glib family of APIs. glib and gobject use reference counting internally to manage object lifetime. The normal way to wrap these is to use a garbage collected peer object which holds a reference to the glib object, and which drops the reference when the peer gets finalised; this means that the glib object is kept alive while the application is using the peer. I've done this

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I'm working on a project these days. A third party library was included in my project, and the library is based on glib. That really make me crazy. Can you everybody tell me what should I do? How to use glib on an iphone application? Dose apple allow us use glib for iphone

问题 In my normal dev environment (ubuntu), I don't have any issues linking against GLib-2.0, however when I attempt to build on fresh install of Debian Squeeze, I run into errors linking GLib. configure.ac: ...

问题 I am using GLib to manage a linked list. I am declaring 2 structs and the placing them in a linked list as follows. Asteroid asteroid = {0,0,50,50,50} Asteroid asteroids = {0,0,200,200,50}; GList *asteroidList = NULL; asteroidList = g_list_append(asteroidList, &asteroid); asteroidList = g_list_append(asteroidList, &asteroids); Then i use the following function to traverse the list and calla function that draws the struct to the screen as a circle as follows void drawAsteroids(){ GList *list =

问题 Trying to compile and run a sample appsrc code after having successfully executed several tutorials. This is a documentation code, supposed it to run but ...
