Just tried to compile this on Ubuntu 20.04.2 LTS, but it fails:

g++ -Wall -Werror -g  -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -std=c++98 -Wconversion -W -Wno-unused-parameter -c freera.cpp -o freera.o -I./include  -I./include/lua

cc1plus: all warnings being treated as errors
make[1]: *** [Makefile:40: freera.o] Error 1
make[1]: Leaving directory '/home/squigley/src/freera++/src'
make: *** [Makefile:12: default] Error 2

The "cc1plus: all warnings being treated as errors" looked suspect, so I edited the config file, and removed "-Werror", which allowed it to compile, however attempting to run it:

$ ./freera
