The following commands install cross-compilers needed for creating
table in the second part or Ahmed's Report 2:

sudo apt-get install g++
sudo apt-get install g++-aarch64-linux-gnu
sudo apt-get install g++-alpha-linux-gnu
sudo apt-get install g++-arm-linux-gnueabi
sudo apt-get install g++-hppa-linux-gnu
sudo apt-get install g++-m68k-linux-gnu
sudo apt-get install g++-mips-linux-gnu
sudo apt-get install g++-mips64-linux-gnuabi64
sudo apt-get install g++-mips64el-linux-gnuabi64
sudo apt-get install g++-mipsel-linux-gnu
sudo apt-get install g++-powerpc-linux-gnu
sudo apt-get install g++-powerpc64-linux-gnu
sudo apt-get install g++-powerpc64le-linux-gnu
sudo apt-get install g++-riscv64-linux-gnu
sudo apt-get install g++-s390x-linux-gnu
sudo apt-get install g++-sh4-linux-gnu
sudo apt-get install g++-sparc64-linux-gnu

Ahmed, I think this should be in an Appendix section of Report 2.

Sincerely,
Aleksandar
