将 tesseract 构建为 DLL 动态 link 库

Question

我正在使用这个 .NET 包装器 https://github.com/charlesw/tesseract，我想更新包含的 tesseract 和 leptonica DLL，但经过长时间的 google 搜索后，我无法从原始 tesseract 生成它们和 leptonica github 存储库。

我已经在 charlesw 存储库上询问但没有得到任何回复 (https://github.com/charlesw/tesseract/issues/486)。

非常感谢任何有关如何构建 DLL 的帮助。

谢谢！

回答：（感谢user898678的link）使用 bucket401 博客 post 教程我提取了生成所需的部分：

leptonica-X.XX.X.dll
tesseract.exe
tesseractXX.dll

并创建了这个 buildTesseractLeptonica.bat :

mkdir buildTesseractLeptonica
cd buildTesseractLeptonica
mkdir bin

set INSTALL_DIR=%cd%
set PATH=%PATH%;%INSTALL_DIR%\bin

call "c:\Program Files (x86)\Microsoft Visual Studio19\Community\VC\Auxiliary\Build\vcvars64.bat" x64
set INCLUDE=%INCLUDE%;%INSTALL_DIR%\include
set LIBPATH=%LIBPATH%;%INSTALL_DIR%\lib
set TESSDATA_PREFIX=%INSTALL_DIR%\share\tesseract\tessdata


git clone --depth 1 https://github.com/DanBloomberg/leptonica.git
cd leptonica
cmake -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%INSTALL_DIR% -DCMAKE_PREFIX_PATH=%INSTALL_DIR% -DBUILD_PROG=OFF -DSW_BUILD=OFF -DBUILD_SHARED_LIBS=ON
cmake --build build  --config Release --target install
cd ..


git clone --depth 1 https://github.com/tesseract-ocr/tesseract.git
cd tesseract
cmake -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%INSTALL_DIR%  -DCMAKE_PREFIX_PATH=%INSTALL_DIR% -DLeptonica_DIR=%INSTALL_DIR%\lib\cmake -DBUILD_TRAINING_TOOLS=OFF -DSW_BUILD=OFF -DOPENMP_BUILD=OFF -DBUILD_SHARED_LIBS=ON
cmake --build build --config Release --target install
cd ..
