## autotools (LINUX/UNIX , msys...)
|
|
|
|
If you have cloned Tesseract from GitHub, you must generate
|
|
the configure script.
|
|
|
|
If you have tesseract 4.0x installation in your system, please remove it
|
|
before new build.
|
|
|
|
You need Leptonica 1.74.2 (minimum) for Tesseract 4.0x.
|
|
|
|
Known dependencies for training tools (excluding leptonica):
|
|
|
|
* compiler with c++17 support
|
|
* automake
|
|
* pkg-config
|
|
* pango-devel
|
|
* cairo-devel
|
|
* icu-devel
|
|
|
|
So, the steps for making Tesseract are:
|
|
|
|
./autogen.sh
|
|
./configure
|
|
make
|
|
sudo make install
|
|
sudo ldconfig
|
|
make training
|
|
sudo make training-install
|
|
|
|
You need to install at least English language and OSD traineddata files to
|
|
`TESSDATA_PREFIX` directory.
|
|
|
|
You can retrieve single file with tools like [wget](https://www.gnu.org/software/wget/), [curl](https://curl.haxx.se/), [GithubDownloader](https://github.com/intezer/GithubDownloader) or browser.
|
|
|
|
All language data files can be retrieved from git repository (useful only for packagers!).
|
|
(Repository is huge - more that 1.2 GB. You do NOT need to download traineddata files for
|
|
all languages).
|
|
|
|
git clone https://github.com/tesseract-ocr/tessdata.git tesseract-ocr.tessdata
|
|
|
|
You need an Internet connection and [curl](https://curl.haxx.se/) to compile `ScrollView.jar`
|
|
because the build will automatically download
|
|
[piccolo2d-core-3.0.1.jar](https://search.maven.org/remotecontent?filepath=org/piccolo2d/piccolo2d-core/3.0.1/piccolo2d-core-3.0.1.jar) and
|
|
[piccolo2d-extras-3.0.1.jar](https://search.maven.org/remotecontent?filepath=org/piccolo2d/piccolo2d-extras/3.0.1/piccolo2d-extras-3.0.1.jar) and
|
|
[jaxb-api-2.3.1.jar](http://search.maven.org/remotecontent?filepath=javax/xml/bind/jaxb-api/2.3.1/jaxb-api-2.3.1.jar) and place them to `tesseract/java`.
|
|
|
|
Just run:
|
|
|
|
make ScrollView.jar
|
|
|
|
and follow the instruction on [Viewer Debugging](https://tesseract-ocr.github.io/tessdoc/ViewerDebugging.html).
|
|
|
|
## cmake
|
|
|
|
There is alternative build system based on multiplatform [cmake](https://cmake.org/)
|
|
|
|
### LINUX
|
|
|
|
mkdir build
|
|
cd build && cmake .. && make
|
|
sudo make install
|
|
|
|
### WINDOWS
|
|
|
|
See the [documentation](https://tesseract-ocr.github.io/tessdoc/) for more information on this.
