GTK C“找不到信号处理程序''。你用-rdynamic编译了吗？”

Question

所以我尝试关闭一个窗口（而不是破坏主窗口）的小尝试前进了一点，但又撞到了另一块石头。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喷出错误"Could not find signal handler 'on_window_sidebar1_back_clicked'. Did you compile with -rdynamic?。

我用 -rdynamic 运行我的编译器并没有帮助。

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！长）

我的问题是用户端的错误。我忘了清理终端设备上的构建，并且那里有一些重叠的目录。在移动存储库时，Linux 决定优先考虑旧的。问题解决了，令人惊讶的是，代码有效。

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.
 }

并将我的信号改短一些以避免（人类）记忆问题。
