【中文标题】我正在尝试用 C 构建一个示例 gtk+【英文标题】:I am trying to build a example gtk+ with C 【发布时间】:2021-08-08 03:19:21 【问题描述】:我正在尝试在 C 上构建我的第一个 gtk+ 程序
我正在使用 simon long 的 C Gui 编程书来学习,我从书中复制了下面的代码
#include <stdio.h>
#include <gtk/gtk.h>
int main (int argc, char *argv[])
gtk_init (&argc, &argv);
GtkWidget *win = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_show (win);
gtk_main ();
return 0;
编译器给我以下错误:
gcc -o bessewellapp bessewellapp.c -Wall `pkg-config --cflags --libs gtk+-2.0` -export-dynamic

我不知道我的代码有什么问题,知道吗?
【问题讨论】:
摆脱#include <stdio.h>
。该包含来自libc
,GTK+ 不需要它。
你读过那些消息了吗?
您是否尝试同时使用 GTK2 和 GTK3?如果没有,你不应该通过添加两个标签来混淆读者。
当您尝试编译该代码时,您使用的确切命令是什么?
【参考方案1】:
在您要提供其他信息之前,只需在文件顶部添加以下行即可删除它:
#define GTK_DISABLE_DEPRECATED
应该是这样的:
#define GTK_DISABLE_DEPRECATED
#include <gtk/gtk.h>
int main ( int argc, char *argv[] )
gtk_init ( &argc, &argv );
/// ***
GtkWidget *win = gtk_window_new ( GTK_WINDOW_TOPLEVEL );
/// ***
gtk_widget_show ( win );
/// ***
gtk_main ();
