在fedora9中编译安装qterm-0.5.2的故障解决
刚刚发表了一篇在fedora中安装qterm-0.5.1的方法介绍。
昨天下载了最最新的qterm-0.5.2，可是怎么编译都是报错，意思是说找不到abs函数，可abs函数明明就是在stdlib.h中阿。
报错信息如下：
[ 64%] Building CXX object src/CMakeFiles/qterm.dir/qtermbbs.o

make[1]: *** [src/CMakeFiles/qterm.dir/all] Error 2
make: *** [all] Error 2
解决办法：
将qtermbuffer.cpp中的abs都替换为qAbs即可！
两个教训：
一是“一定仔细看出错信息”！
二是“别以为源码包没有错”！！
