In the first step, we created a simple Hello, World! C++ program. We put this into the ~/test directory, which makes it accessible from the Docker container running Linux.
To build the source code, we switched to the Ubuntu shell.
If we try to run a standard Linux g++ compiler to build it, we will get an executable for the build platform, which is x86. However, we need an executable for the ARM platform. To build it, we need a version of the compiler that can run on x86, building the ARM code.
As a preliminary step, we need to update the information about the packages available in the Ubuntu packages distributive:
We can install ...
