Hello,

What is the usage of yum install -y redhat-lsb? You said # To get the version, what version? If I'm not to install it, can I still install the devtoolset-6?

Although I have searched redhat-lsb, I'm still not understand how it affects the whole script. Thanks.

LSB is Linux Standard Base Distribution
It is the version of Linux running in the system
cat /etc/rhedhat-release
cat /etc/release
cat /etc/os-release
Thanks

yeah I think that the ycmd build.py uses lsb-release to get the OS version

Thanks Ben
