[Bro] Question about GCC version error while run configure

[SJ Lee]

Hello everyone,
I recently need to re-build a bro package, but keep failed to run configure
command because of GCC version.

By default does not have a high version, so I installed devtoolset and did
symbolic link  like below,  Can anyone kindly help this issue?

 /usr/bin/c++ -> /opt/rh/devtoolset-3/root/usr/bin/c++
/usr/bin/gcc -> /opt/rh/devtoolset-3/root/usr/bin/gcc.

[Here is details]
 CMake Error at cmake/RequireCXX11.cmake:40 (message):
  GCC version must be at least 4.8 for C++11 support, detected: 4.4.7
Call Stack (most recent call first):
  CMakeLists.txt:168 (include)
