GTK C "Could not find signal handler ''. Did you compile with -rdynamic? "
所以我试图在一秒钟内关闭 window（而不是摧毁主 window）的小尝试进行了一点，但又撞到了另一块石头。代码编译时没有错误或警告，但是当我按下按钮触发 "on_window_sidebar1_back_clicked" 时，控制台 运行ning 说程序会喷出错误 "Could not find signal handler 'on_window_sidebar1_back_clicked'. Did you compile with -rdynamic?.
我 运行 我的编译器有 -rdynamic 但它没有帮助。
部分代码负责关闭window:
void on_window_sidebar1_back_clicked()
{
void
gtk_close_window(secondWindow); //sedondWindow is defined further up. no errors related to it.
}
