[ GUIDE ] Centos 6 gcc update to 4.9

[Keitenai]

Hello!

Same with many rAthena users, I too have encountered the massive warnings upon compiling the latest git.

So i took my time to google around and finally was able to find something that could solve this issue without using Centos7.

Just follow the sequence below and you'll have your gcc updated to 4.9 in no time!

• First you need to login as root.
  • yum install centos-release-scl
  • yum install devtoolset-4-toolchain
  • scl enable devtoolset-4 bash
• Then login to your non-root "user".
  • scl enable devtoolset-4 bash
• After the 1st and 2nd step, you may now check your gcc version
  • gcc --version
  • g++ --version
  • gfortran --version

 

Recompile your rathena and you will find that the shadow warnings are all gone =)

CHEERS!

 

UPDATE: from devtoolset-3  to  devtoolset-4
