Windows and Mac maintainers wanted.
Building
This links to the C libraries leptonica and tesseract.
On Ubuntu and derivatives the additional dependencies can be installed by running:
sudo apt-get install libleptonica-dev libtesseract-dev clang
On Fedora 30 the additional dependencies can be installed by running:
sudo dnf install leptonica-devel tesseract-devel clang
On Termux 2019 (Android, Android on Chromebooks) the additional dependencies can be installed by running:
pkg install libclang leptonica-dev tesseract-dev
Building on Windows
On Windows, this library uses Microsoft's vcpkg to provide tesseract.
Please install vcpkg and set up user wide integration or vcpkg crate won't be able to find a library.
To install tesseract
REM from the vcpkg directory
REM 32 bit
.\vcpkg install tesseract:x86-windows
REM 64 bit
.\vcpkg install tesseract:x64-windows
vcpkg allows building either dynamically or statically linked application
if you prefer dynamic linking
SET VCPKGRS_DYNAMIC=true
for statically linked libraries
SET RUSTFLAGS=-Ctarget-feature=+crt-static
To run the tests please download the English trained data to this directory and set
SET TESSDATA_PREFIX=.
If you prefer to compile tesseract yourself (Because, for example, you could not get vcpkg to build using clang-cl.exe), you can set these environment variables: TESSERACT_INCLUDE_PATHS
, TESSERACT_LINK_PATHS
and TESSERACT_LINK_LIBS
.
For example:
set TESSERACT_INCLUDE_PATHS=D:\tesseract\build\include
set TESSERACT_LINK_PATHS=D:\tesseract\build\lib
set TESSERACT_LINK_LIBS=tesseract41
