c++ - Valgrind-libgtk-x11

Question

我纠正了我在 Qt 中编写的程序中的所有内存泄漏。
我发现了一些无法处理的错误。

我的主要功能

#include "mainwindow.hh"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec(); //this is my 9th line
}

一整天都在尝试修复它，但我不知道这是什么意思。
有人可以帮助我吗？

对于您不感兴趣且无法解决问题的库，您创建 valgrind 抑制文件，它们将不会再次显示

请看说明书
