The problem has something to do with building the C core of igraph. What steps do I take to resolve this error?
My system info, if relevant:
tl;dr Use the official Python distribution for Windows, or use Anaconda.
You should not use python-igraph with the Python included in MSYS2 unless you have a very good reason. This Python is not compatible with the official Python distribution on Windows, which means that you will not be able to install binary wheels from PyPI, and will need to compile everything from source. As you discovered, that is not always trivial.
If you have a truly good reason to use this Python with igraph, the simplest way is the following:
pacman -S mingw-w64-x86_64-igraphpip from MSYS2: pacman -S mingw-w64-x86_64-python-piptexttable: pip install texttableigraph, and link to the existing C library: pip install igraph --install-option="--use-pkg-config"By going this route, you are treading in uncharted waters. Expect problems that you will need to resolve on your own.
