如何从 Linux 应用程序中排除/usr/include 路径? [英] How to Exclude /usr/include Path from Linux Application?

问题描述

我遇到了一个无法避免的问题.Redhat 6(或大多数 linux 包)带有一个默认的 QT 包，在/usr/lib 和/usr/include 文件夹中安装了 headers/etc.

I am running into a problem I have not been able to avoid. Redhat 6 (or most linux packages) comes with a default QT package installed with headers/etc in the /usr/lib and /usr/include folders.

现在，我想在不删除旧版本的情况下链接到新版本的 QT.不幸的是，由于头文件在/include/文件夹中，gcc 会自动找到它们，然后使用错误的包含文件(而不是我在别处拥有的文件).

Now, I am wanting to link against a newer version of QT without removing the older version. Unfortunately, since the headers are in the /include/ folder, gcc automatically finds them, and then uses the wrong include files (instead of those which I have elsewhere).

我似乎无法阻止编译器自动执行此操作.我以前通过简单地手动删除旧的库/头文件来解决这个问题，但从长远来看，这是一个糟糕的解决方案.

I cannot seem to stop the compiler from automatically doing this. I have gotten around it previously by simply manually removing the old libraries/headers but this is a terrible solution long term.

我也不认为这个问题是 QT 特有的，它恰好是我当前的实例.

I do not think this problem is specific to QT either, it just happens to be my current instance of it.

有什么建议吗?

非常感谢:)

推荐答案

结果证明我的问题与使用的 qmake 版本不正确有关.它正在寻找以前版本的 qmake，即使它来自 qt4，它也链接到了错误的包含.

My issue turned out to be related to an incorrect version of qmake being used. It was finding a previous version of qmake, and even though it was from qt4, it was linking to the wrong includes.

更新 qmake 路径可以解决此问题.

Updating the qmake paths worked to fix this issue.
