make 过程中安装时的 Tesseract 问题

Question

我正在尝试使用 gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 在 Debian 9 上安装 tesseract-ocr。

我运行按照下面的顺序，按照这个https://github.com/tesseract-ocr/tessdoc/blob/master/Compiling-%E2%80%93-GitInstallation.md

./autogen.sh 。/配置制作

现在，当我运行 make 时，出现以下错误：

我已经尝试了 id 应该解决这个问题的 popst 安装指令，但没有成功

make all-recursive

感谢任何帮助。

升级你的编译器——当前的 tesseract 需要一个支持 c++17 的现代编译器。
