我正在使用JavaCPP预设项目来构建Leptonica和Tesseract。我已经设法使用以下命令构建了Leptonica 1.7：
cd leptonica
./cppbuild.sh install leptonica
cd cppbuild/linux-x86_64/leptonica-1.72/
./configure
make && sudo make install
cd ../../../
mvn clean install
cd ..
编译的库是/usr/local/lib
当我尝试使用以下命令构建 Tesseract 时，出现此错误：
./cppbuild.sh install tesseract
./configure: line 17620: syntax error near unexpected token `LEPTONICA,'
./configure: line 17620: `PKG_CHECK_MODULES(LEPTONICA, lept >= 1.74, have_lept=true, have_lept=false)'
/opt/javacpp-presets/tesseract
然后我放了完整的跟踪：

我从自动会议使用的版本是 2.9。
提前致谢
今年早些时候，在 github 帐户上提出了类似的问题。一条评论回应说：
感谢您的这份报告。您在安装指南中发现了一个错误：我们没有提到软件包 pkg-config 是必需的。我在 Wiki 页面中修复了它，并将发送拉取请求以更新分发的 INSTALL* 文件。
我今天在OS X上遇到了同样的问题，安装pkg-config似乎已经解决了这个问题。
