Question

由于我需要C ++ 14支持其中一个项目，因此我尝试使用http://en.librehat.com/blog/build-gcc-5-dot-2-on-rhel-6/中描述的步骤在我的RHEL6实例上构建GCC5.2。但是，尽管这些步骤在RHEL5实例上运行良好，但在构建libgomp的步骤中，我在AmazonLinux上收到以下错误：

一些狩猎（http://gcc.1065356.n5.nabble.com/Build-gcc-4-8-2-error-gcc-4-8-1-x86-64-unknown-linux-gnu-libgomp-td977436.html）表明编译器无法找到libc库。但是我无法找到解决问题的方法。有没有人早些时候遇到类似的问题？知道发生了什么事吗？

另一种方法是使用RH Developer Toolset - 订阅的一部分。它现在支持RHEL 6和7上的GCC 5.2：http://developerblog.redhat.com/2015/11/17/gcc-5-developer-toolset-4-generally-available/
