Context: I’m attempting to build growisofs from its source code (version 7.1) using the following command in the Cygwin terminal: make TARGET_ARCH=-m64, but it gives me several errors when I attempt to do it. These all appear to be problems with the code itself, but I don’t know C++ or C and thus cannot fix them myself presently. Many of these errors are also formulaic so I’m mainly hoping I can get solutions for the most common ones.

I have tried several different terminals, including Git Bash, UCRT64, MinGW64 and, of course, Cygwin. I have installed every package Cygwin allows me to, including gcc and other compiling tools, but I keep getting the same errors. These are the messages in their entirety, and they pertain to only growisofs_mmc.cpp and transport.hxx.
