centos 6.2安装SWFTOOLS-0.9.2的时候，在执行make install时报错

安装SWFTOOLS-0.9.2的时候，在执行make install时报错，
rm -f /usr/local/share/swftools/swfs/default_viewer.swf -o -L /usr/local/share/swftools/swfs/default_viewer.swf
rm：无效选项 -- o
请尝试执行"rm --help"来获取更多信息。
make[1]: *** [install] 错误 1
make[1]: Leaving directory `/root/swftools-0.9.2/swfs'
make: *** [install] 错误 2

从错误提示来看是rm命令给的选项有问题，没有-o和-L选项，所以报错，排查办法，就是找出这个报错的语句在哪个文件中，修改其中的语句

在swftools的目录中查找包含“default_viewer”字符串文件名

find ./ |xargs grep -r -i "default_viewer"

通过上面的命令可以找到下面的文件

[root@localhost swftools-0.9.2]# find ./ |xargs grep -r -i default_viewer

分别修改上面红色标注的2个文件。

然后在执行make install 成功！
