The default GCC version of CentOS7.7 is gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)
#gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)
#cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)

There are two solutions
1. Manually compile gcc>4.8
Self compilation
2. Install devtoolset-8 (use the higher version gcc (GCC) 8.3.1 20190311
yum install centos-release-scl -y
yum install devtoolset-8 -y
Enable devtoolset-8
#scl enable devtoolset-8 -- bash
#source /opt/rh/devtoolset-8/enable

Use higher version gcc (GCC) 8.3.1 20190311 before temporary compilation (this method is recommended)
export CC=/opt/rh/devtoolset-8/root/usr/bin/gcc
export CPP=/opt/rh/devtoolset-8/root/usr/bin/cpp
export CXX=/opt/rh/devtoolset-8/root/usr/bin/c++
Continue compiling and installing aria 2-1.35.0
