Iguana is written in C++ and is linked to GLIBC runtime libraries which are part of the operating system. The catch with this is that your system needs to be modern enough to have the libraries that Iguana requires.
As of the date of writing this documentation this version was 2.34. How do you tell what version of libraries your system has? This little code fragment should do the trick:
echo $(ldd --version | head -n 1 | awk '{print $NF}')
It will print out what version of GLIBC libraries are on your system.
