c++ - GCC 库中的未定义引用

Question

我正在尝试在 Linux 上构建我公司主要应用程序的静态链接版本。该应用程序使用 Qt 5.3，如果我使用带有 Qt 的调试/动态链接构建，一切都编译得很好。但是，在进行静态构建时，我从.a库中收到了许多奇怪的错误。/usr/lib/x86_64-linux-gnu

5.3/Src/qtbase/我在 Qt 下载的文件夹中使用以下命令为静态构建配置了 Qt 5.3.1 ：

./configure -release -static -opensource -nomake tools -nomake examples --force-asserts -no-sql-sqlite -no-libjpeg -no-opengl -no-gif -qt-xcb -qpa xcb
make clean
make sub-src

然后我使用 QMake 和 make 构建应用程序，在 Emu 项目目录中使用以下命令：

/path/to/qt-static/qmake -r -spec linux-g++ emu.pro
make clean
make

最后一个make命令在最后的链接步骤中产生以下错误：

但是我已经安装了所有可以找到的 X Window System 库...

我不知道为什么我在标准库中遇到错误。那么为什么会发生这种情况，我该如何解决呢？
