>>As most of us here, I run an over 100-K lines compact and complex code base. Moving stuff means a lot more than a build process!
It can be just a build process.
Since 2009 Chen has done an amazing job debugging and refining his VFP Compiler. In 2017 the only "gotcha" I encounter with extremely complex code, some of which dates back to the 1990s, is that decomposition (part of obfuscation) can push already complicated code past VFP's default nesting limit, causing a ? 96 error. This is covered in Chen's instructions and IME it's 100% eliminated by a STACKSIZE setting in your config.fpw.
The only other "gotcha" to watch is file locations, especially with earlier VC runtime installers, since UAC may invisibly stop VC MAKE functioning properly. If VFP Compiler seems to lock at the point where you expect to see a MAKE dos window: try running VFP Compiler as Administrator which will confirm whether it's a security barrier.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
