QT 4.4 中出现 BUG 参考文献是本文要介绍的内容，不多说，我们先来看内容。环境：CentOS 5, GCC 4.1.1, QT 4.4.0, Open Source Edition, x11 version.
下载下来 qt-x11-opensource-src-4.4.0.tar.gz，约 100M，解压，
Run configure 命令，选择不需要 SVG 模块，./configure -debug -no-svg
然后在 run make 命令，failed。
也曾经尝试过其它的配置，如，不需要 webkit, not qt3 support, etc, everyone successful，
但愿 QT 的下一个 release 解决这个问题。
这里是 build failed information:
