解决 PHP 插件提示 need re2c 问题

后知后觉 暂无评论

在编译 xlswriter 插件时(PECL 组件)遇到了以下提示。

这个提示是「警告」,忽略其实也能正常编译。但是没有警告才能保证全部功能工作正常。

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.

Re2c 是一个免费、开源的 C语言 和 C++语言 生成器。它的主要目标是生成快速的语法分析器,此语法分析器的匹配速度或超过精心优化的手写代码的速度。

Re2c is a free and open-source lexer generator for C and C++. Its main goal is to generate fast lexers that match or exceed the speed of carefully optimized hand-written code. Re2c uses direct encoding of finite-state machines instead of the table-driven approach, and optimizes the generated code.

官方 Github 仓库官方 SourceForge 仓库(可能有版本提交速率差异),建议使用 Github 仓库。

源码

$ wget https://github.com/skvadrik/re2c/releases/download/1.3/re2c-1.3.tar.xz

解压

$ xz -d re2c-1.3.tar.xz && tar xf re2c-1.3.tar

编译

$ ./configure && make && make install
注意:不同的发行版要安装基础编译依赖,红帽系 dnf group install 'Development Tools' ,Debian 系 apt install build-essential

使用 re2c 的程序即可正常编译。比如 PHP 插件 xlswriter 。
