  • Did anyone manage to build this? It seems something is missing, or I am doing something wrong. The build fails due to missing symbols for me. Also, interestingly the assembler complained about one line in a certain file being too long. Fortunately that lines was just a comment, so it was easy to fix that.

    • This explains it, although it is not really Git's fault as that article suggests, but rather the charset conversions to UTF-8 that broke things. With all that fixed it builds fine. I've been using DOSBOX and since all the required build tools are included in the repo, it is easy to build.
