1、在编译qt-everywhere-opensource-src-4.8.5时，出现如下问题
gmake: g++: Command not found
gmake: *** [project.o] Error 127
make: *** No targets specified and no makefile found. Stop.2、查找错误原因，使用指令yum search “gcc-c++”
[root@localhost arm-qte-4.8.5]# yum search "gcc-c++"

============================= N/S Matched: gcc-c++ =============================
gcc-c++.i686 : C++ support for GCC
Name and summary matches only, use "search all" for everything.3、使用指令yum install “gcc-c++.i686” 安装对应的文件
[root@localhost arm-qte-4.8.5]# yum install "gcc-c++.i686"
