我正在尝试用 C 构建一个示例 gtk+

Question

我正在尝试构建我的第一个用 C 编写的 gtk+ 程序

我使用 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

我不知道我的代码出了什么问题，有什么想法吗？

Answer 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将其删除：

#define GTK_DISABLE_DEPRECATED

它应该看起来像这样：

#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 ();
}

Answer 2

编译时错误..

gcc -o bessewellapp bessewellapp.c -Wall

pkg-config --cflags --libs gtk+-2.0

-导出动态

为什么gtk+-2.0没有这个文件。

尝试gtk+2.0删除-
