c - GTK C "Could not find signal handler ''。你是用-rdynamic编译的吗？ ”

Question

因此，我试图再次关闭一个窗口(而不是破坏主窗口)的小尝试进行了一点，但又撞到了另一 block 石头。代码编译时没有错误或警告，但是当我按下触发“on_window_sidebar1_back_clicked”的按钮时，运行所述程序的控制台会发出错误“无法找到信号处理程序'on_window_sidebar1_back_clicked'。您是否使用-rdynamic进行编译？.

我用 -rdynamic 运行我的编译器，但没有帮助。

负责关闭窗口的部分代码:

void on_window_sidebar1_back_clicked() 
 {
    void
    gtk_close_window(secondWindow); //sedondWindow is defined further up. no errors related to it.
 }

我的window_main.glade(警告!很长)

我的问题是用户端出现错误。我忘记清理终端设备上的构建，并且其中有一些重叠的目录。当移动存储库时，Linux 决定优先考虑旧的存储库。问题解决了，令人惊讶的是，代码可以工作。

编辑:

我也改用了

void on_sidebar1_back_clicked()
 {
    gtk_widget_destroy(GTK_WIDGET(secondWindow));
 }

而不是

void on_window_sidebar1_back_clicked() 
 {
    void
    gtk_close_window(secondWindow); //sedondWindow is defined further up. no errors related to it.
 }

并将我的信号更改为短一点以避免(人类)内存问题。
