CentOS 6.8 上的 xgboost 构建错误
xgboost build error on CentOS 6.8
操作系统：CentOS 6.8
编译器：gcc 4.8.2 和 g++4.8.2
重现步骤
只需按照 installation guide
中的步骤操作即可
我的脚步
git clone --recursive https://github.com/dmlc/xgboost
git submodule init
git submodule update
cd xgboost
make -j4
然后我得到下面的错误

对于根本原因有什么建议吗？
我不熟悉 xgboost，但是从错误中可以明显看出某些 ASM 代码没有正确生成：
expecting string instruction after `rep'
ASM中的REP关键字前缀表示"repeat this instruction a number of times (defined by the C register)".
不过也可能是您的工具链有问题。实际上，如果生成此错误的代码不依赖于内联 ASM，这似乎是一个工具链错误。
某些版本的 binutils 认为 rep ret 无效，而实际上它是一个有效的 x86-64 指令。
尝试升级到 binutils 2.23.52.0.1
