Mojave 编译安装 tesseract-4.1.1

前言

顺便学习下Python，尝试使用Python3安装tesseract进行文字识别，结果踩了好深一个坑，特此记念……

好多坑，好多坑……

参考彭世瑜的这一篇：https://blog.csdn.net/mouday/article/details/104398303

1、安装好多依赖

# Packages which are always needed.
brew install automake autoconf libtool
brew install pkgconfig
brew install icu4c
brew install leptonica# 如果你需要用到训练工具，要安装 pango.
brew install pango# Optional packages for extra features
brew install libarchive# Optional package for builds using g++.
brew install gcc

2、下载并解压 tesseract-4.1.1.tar.gz

下载地址为：https://github.com/tesseract-ocr/tesseract/releases

在这里插入图片描述

3、进入安装阶段

我的直接解压到 /Users/Jacky/tesseract-4.1.1

cd tesseract-4.1.1
./autogen.sh
mkdir build
cd build# 以下为执行我的配置，请各位按照自己的版本号进行设置./configure cairo_LIBS=-L/usr/local/Cellar/cairo/1.16.0_3/lib cairo_CFLAGS=-I/usr/local/Cellar/cairo/1.16.0_3/include pango_LIBS=-L/usr/local/Cellar/pango/1.44.7/lib pango_CFLAGS=-I/usr/local/Cellar/pango/1.44.7/include/pango-1.0 icu4c_LIBS=-L/usr/local/Cellar/icu4c/64.2/lib icu4c_CFLAGS=-I/usr/local/Cellar/icu4c/64.2/include  CC=gcc-9 CXX=g++-9 CPPFLAGS='-I/usr/local/opt/icu4c/include -I/usr/local/Cellar/glib/2.64.1_1/include/glib-2.0 -I/usr/local/Cellar/glib/2.64.1_1/lib/glib-2.0/include -I/usr/local/Cellar/cairo/1.16.0_3/include/cairo -I/usr/local/Cellar/freetype/2.10.1/include/freetype2 -I/usr/local/Cellar/fontconfig/2.13.1/include' LDFLAGS='-L/usr/local/opt/icu4c/lib -L/usr/local/Cellar/giflib/5.2.1/lib -L/usr/local/Cellar/pango/1.44.7/lib -L/usr/local/Cellar/glib/2.64.1_1/lib -L/usr/local/Cellar/cairo/1.16.0_3/lib -L/usr/local/Cellar/fontconfig/2.13.1/lib' --prefix=/Users/Jacky/tesseract.4.1.1make -j# Optionally install Tesseract.
sudo make install# Optionally build and install training tools.
make trainingsudo make training-install

比如：/usr/local/Cellar/cairo/我的版本号为1.16.0_3
在这里插入图片描述 还有一个需要注意的是gcc的版本号，这里我的为9

执行configure过程遇到的问题

configure: WARNING: pango 1.22.0 or higher is required, but was not found.
configure: WARNING: Training tools WILL NOT be built.
configure: WARNING: Try to install libpango1.0-dev package.
checking for cairo... no
configure: WARNING: Training tools WILL NOT be built because of missing cairo library.
configure: WARNING: Try to install libcairo-dev?? package.
checking that generated files are newer than configure... done

我的pango的版本已经是1.44.7，总是提示我pango 1.22.0 or higher is required
请按照上面的./configure 里的设置更改为自己的版本号

libcairo-dev也是需要在./configure里直接指定

cairo_LIBS=-L/usr/local/Cellar/cairo/1.16.0_3/lib
cairo_CFLAGS=-I/usr/local/Cellar/cairo/1.16.0_3/include
pango_LIBS=-L/usr/local/Cellar/pango/1.44.7/lib
pango_CFLAGS=-I/usr/local/Cellar/pango/1.44.7/include/pango-1.0

接着你会遇到icu的问题……

然后各种搜索，mac没有icu，只有icu4c，可是我已经装了icu4c的
在这里插入图片描述 漫长的搜索过程……

然后又安装了PyICU，又在bash_profile文件中加了一些路径

# 没搞懂为什么要装这个 pyicu
pip3 install pyicuopen ~/.bash_profile# 增加了如下的路径
export PATH="/usr/local/opt/icu4c/bin:$PATH"
export PATH="/usr/local/opt/icu4c/sbin:$PATH"
export ICU_VERSION=64
export PYICU_INCLUDES=/usr/local/Cellar/icu4c/64.2/include
export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/64.2/lib
export PYICU_CFLAGS=-std=c++11
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"source ~/.bash_profile
