我正在尝试使用OpenSSL支持进行Qt(版本5.4.1)的静态构建.我配置如下:
configure -opensource -release -c++11 -static -platform win32-msvc2013
-openssl-linked -I C:\OpenSSL-Win32\include
-L C:\OpenSSL-Win32\lib\VC\static
-nomake examples -nomake tests
include和lib目录有效.我收到大量的链接错误Qt5Network.lib.

我已经读过复制构造函数在将对象作为参数传递给函数或从函数返回对象时以及通过赋值初始化变量时被调用。在这种情况下也可以调用它吗，假设 D 有复制构造函数？
D* pd1 = new D;
D* pd2 = new D(*pd1);
