what is the output of tesseract -v?

Client is, for now, just a command wrapper, requiring available executable bin.

[jackluo2012]

[root@localhost src]# tesseract -v
tesseract 4.00.00alpha
leptonica-1.74.1
libjpeg 6b (libjpeg-turbo 1.2.90) : libpng 1.5.13 : libtiff 4.0.3 : zlib 1.2.7

Found AVX
Found SSE

then, you can see there is no tesseract versions supported. 4.00.00alpha is out of range.
