Jeff King suggested how you can update the build command to get it working. In general, I think people sometimes overthink what is involved in a build: something like cc *.c plus appropriate warning, optimization, debug, -D, and library flags should work just fine. If you haven't already read it, I also recommend reading https://www.kernel.org/pub/software/scm/git/docs/user-manual.html#hacking-git. If you have ideas for improving the text there (perhaps with suggested build instructions?), patches to Documentation/user-manual.txt are very welcome. Thanks and happy hacking, Jonathan
