Font build error?

Question

Fonts

I'm trying to build a Hack font with alternative glyphs from this and this instructions.
I installed all the necessary dependencies (it seems to me that the problem is with ttfautohint), but when starting the build ($ make ttf), an error appears "An error with code 0x90 occurred while loading the reference font
locations (loca) table missingUnable to execute ttfautohint on the Hack -Regular variant set.Build canceled.make
: *** [ttf] ▒▒▒▒▒▒ 1".
The build goes fine at first, but then it throws an error as it approaches the hint.
I have a feeling this is due to ttfautohint itself. I downloaded from off. site archive with ttfautohint and 2 files in it:
ttfautohint.exe and ttfautohintGUI.exe. Until I put ttfautohint.exe here "C:\Users\virtu\ttfautohint-build\local\bin\" the assembly refused to start at all, but then the error still appears, which I indicated above.
Here is the complete build output from the console:
$ make ttf
./build-ttf.sh

Please help me figure it out, I've been asking for a glyph from this author since May of this year, it's a shame it comes out very much ...
