我搜索了google，但是找不到修复过的工具，以前谁也遇到过相同的问题?

I search google,but can't find good ways to fix it ,who has the same issues before?

推荐答案

替换原始gcc可能会导致问题.另一种方法是安装Developer Toolset，它会在原始版本的旁边安装新的gcc版本(当前版本为4.9)，以避免文件冲突.从这里开始: http://developers.redhat.com/products/developertoolset/overview/

Replacing the original gcc can cause problems. The alternative is to install Developer Toolset which installs a new gcc version (currently at 4.9) along side the original to avoid file conflict. Get started here: http://developers.redhat.com/products/developertoolset/overview/
