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？
最佳答案
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
http://valgrind.org/docs/manual/manual-core.html
2.5节抑制错误
关于c++ - Valgrind-libgtk-x11，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27414881/
