You need to load a more recent GCC module. The GNU Compiler Collection (GCC) is an optimizing compiler that contains GLIBCXX (The GNU C Library) and cc1plus (compiler for C++).

• The default version of gcc on Oscar is 4.8.5, which comes installed as part of the OS.
• You can load a more recent module with the following commands:

# Check for available gcc modules on OSCAR 
$ module avail gcc
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ name: gcc*/* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcc/10.2   gcc/4.7.2  gcc/5.4    gcc/6.3    gcc/8.3    
gcc/4.5.4  gcc/4.9.4  gcc/6.2    gcc/7.2   

# Load a newer version 
$ module load gcc/10.2
