Clone this repository to your $T4_WORKSPACE 28 | 2. Execute `docker build -t tesseractshadow/tesseract4cmp $T4_WORKSPACE` (or `./dockerfile.build.sh`) 29 | 30 | ## If something went wrong 31 | You can get into the container using SSH: 32 | - `localhost:4022`, 33 | - user: `root`, 34 | - [password](https://github.com/tesseract-shadow/tesseract-ocr-compilation/blob/fb93548e4ec756bda3dbc0237f58c23053441953/Dockerfile#L41) 35 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
