Linux下编译安装XLib库

新装好的redhat7.3，在安装qt的时候，有时会出现

Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/zhu/Qt/qt-x11-opensource-src-4.5.2/mkspecs/Linux-g++

 

解决这个问题只需要几个库就可以了，实际上只要安装两个库：

sudo yum install libXau-devel

sudo yum install ibX11-devel  （打印信息显示，该package已经安装）

sudo yum install libXext-devel

 

但苦于自己的电脑没有网络，只能手动安装，在安装的过程中，经常产生这样的警告：conflicts with file from package

 

[root@test1 softwares]# rpm -ivh lib64ev4-4.24-1.mga6.x86_64.rpm

解决办法：

 

rpm -ivh perl-base-5.16.3-1.mga3.x86_64.rpm --replacefiles

 

这样就可完成XLib库的安装。
