Error compiling using scons

I am using WSL with Ubuntu under Windows 10. I installed all the relevant libraries to compile the code. However, when attempting to compile using scons -f SConstruct.py I get an error. The full output from the compiler is below.

scons: Reading SConscript files ...
scons: done reading SConscript files.

Do you have any ideas of what the issue could be?
