Hi Suzuki, Sorry for chiming in late, but you may want to try the PPA for Ubuntu Toolchain test builds, which contains compiler builds up to gcc-8 for Ubuntu version as old as 10.04. Much less of a hassle than building GCC yourself, I can tell from experience. Check out https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
