compiling fileZilla on ubuntu 14.04 LTS

Question

I am trying to compiler FileZilla from its source code. It requires C++ 14 support for which gcc4.9 is required. Whatever higher version than 4.8, I try to install, there's no change.

Is gcc4.9 not available for the above ubuntu version?

The error I get is:

checking whether g++ supports C++14 features by default... no
checking whether g++ supports C++14 features with -std=gnu++14... no
checking whether g++ supports C++14 features with -std=gnu++1y... no
checking whether g++ supports C++14 features with -std=c++14... no
checking whether g++ supports C++14 features with -std=c++1y... no
configure: error: *** A compiler with support for C++14 language features is required

Can someone help ?

To install gcc-4.9 g++-4.9 may be helpful, and set it as your default gcc.

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

Then gcc-4.9 will be available in your ubuntu version.

Notes : my version is ubuntu 14.04
