Error building tesseract 4.0.0 about sw

[egorpugin]

Thank you.
I'm working on some updates right now, so you see this isn't working.

I'll post updates here (should not take long).

Ok, try to upgrade client (sw -self-upgrade) or re-download it from website.
Then re-run sw build.

(BTW, 4.0.0 might not work at all. Try everything on master.)

The master version of tesseract always worked. This is a backwards compatibility issue. I still get the same error:

Sw build was added after 4.0.0. In you case sw tries to load cppan.yml which is not adopted for it.
Try to copy sw.cpp from master to 4.0.0 source tree and run it again.
