为什么用qt编出的动态苦很大，比vc编出的大很多 [复制链接]

rt，编译环境是XP, Qt Creator 1.0, 默认设置，release 编出居然450 k, vc下100k都不到，请各位大虾帮忙,多谢！

try not to include all header files in all .h files. Instead define the variables with class names if possible.
For example:

replace your code like

#include "B.h"

class A
{
public:
    B * b;
}

with

class B;

class A
{
public:
    B * b;
}

put include "B.h" in A.cpp

It may help a bit and also compiling may be faster.

我试试

编译器不一样，编译出来的文件大小也不一样。
