Question

为了安装用于深度学习的caffe，我需要在redhat 6.5中将gcc版本从4.4.7升级到4.8.2。

First run ./configure it worked,
then make -j4, it will report 
options.c:11145: error: narrowing conversion of '-0x00000000000000001' from 'int' to 'short unsigned int' inside { }

我搜索谷歌，但无法找到解决问题的好方法，谁之前有同样的问题？

更换原始gcc可能会导致问题。另一种方法是安装Developer Toolset，它在原始版本旁边安装一个新的gcc版本（目前为4.9），以避免文件冲突。从这里开始：http://developers.redhat.com/products/developertoolset/overview/
