Mac環境下編譯安裝tesseract-4.1.1

1、安裝依賴

# Packages which are always needed.
brew install automake autoconf libtool
brew install pkgconfig
brew install icu4c
brew install leptonica

# Packages required for training tools.
brew install pango

# Optional packages for extra features.
brew install libarchive

# Optional package for builds using g++.
brew install gcc      

2、下載下傳解壓tesseract-4.1.1.tar.gz

https://github.com/tesseract-ocr/tesseract/releases

3、編譯安裝

cd tesseract-4.1.1
./autogen.sh
mkdir build
cd build

# Optionally add CXX=g++-8 to the configure command if you really want to use a different compiler.
../configure PKG_CONFIG_PATH=/usr/local/opt/icu4c/lib/pkgconfig:/usr/local/opt/libarchive/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig
make -j

# Optionally install Tesseract.
sudo make install

# Optionally build and install training tools.
make training
sudo make training-install      

4、下載下傳eng.traineddata

https://github.com/tesseract-ocr/tessdata

5、測試

$ tesseract 0384.jpg stdout
0 3 8 4      

圖檔

看報錯路徑，把eng.traineddata檔案拷貝到缺失路徑下，再次測試
