c++ - 使用非默认编译器编译和使用 Qt 时出现问题

Question

我正在尝试编译和使用 Qt。出于某种原因，我必须为我的应用程序使用 g++ 版本 3.4.3，而不是系统上安装的编译器:g++ 4.1.2。我编译 Qt 时将环境变量 CXX 和 CC 设置为旧的 g++，但是当我将我的应用程序与旧的 g++ 链接时，我仍然收到以下错误:

只有使用新的编译器和链接器才能成功链接可执行文件。

有没有人知道如何解决这个问题？

事实证明修改LINK 是不够的，但是当我将PATH 更改为指向旧编译器时，Qt 被编译并仅与旧编译器链接，然后我能够将它与我的程序链接起来。早该想到的……
