编译和使用非默认编译器Qt的问题

我试图编译和使用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。我编译的Qt与环境变量CXX和CC集老G ++，但仍当我联系我的应用程序与旧的G ++我收到以下错误：编译和使用非默认编译器Qt的问题

仅使用新的编译器和链接成功链接可执行文件。

有没有人有关于如何解决这个问题的想法？

你确定你正在与旧的GCC链接？你没有提到设置LINK变量，而且错误看起来像链接器试图链接到不同于3.4的C++库版本，这就是它失败的原因。 – 2011-01-27 15:07:19

是的。我忘了提及它，但我确实设置了LINK变量。不仅如此，我必须通过将配置脚本添加到SYSTEM_VARIABLES列表来修改配置脚本以遵守这个变量。 – 2011-01-30 10:07:27

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，然后我就能够将其与我的程序。应该有这个想法...

gcc 3.x和4.x没有兼容的C++ ABI，甚至有些早期的4.x版本与最近的版本不兼容（阅读gcc 4.2+）。
