    如何在 Mac 上用 Clion 调试 php7 源码

    正文概述 转载于：掘金(BigFish_大鱼)   2021-08-07   396

    一、背景

    据2020年7月份的编程排行榜，php 依然在前10，表明了 php 还是世界上最好的语言。php 的优势很多，只要场景合适，在工作中能用就用了。为了更好的理解这门语言，这几天学习下 php 的源码。网上查资料，不少人直接用 GDB 在 linux 上调试，个人感觉体验很差，容易敲错命令，因此配置了 Clion，可视化的调试 php7 源码。这里对这个步骤做了记录，包括踩的坑。

    二、配置步骤

    1、下载 Clion 软件

    www.jetbrains.com/clion/ 试用30天，有条件的可以购买

    2、编译 php 源码

    a、下载代码

    版本号是7.1.10 www.php.net/distributio…

    b、配置 mac
    • 安装 xcode ，保证cmake命令可用
    • 安装libiconv
    brew install libiconv
配置环境变量
echo 'export PATH="/usr/local/opt/libiconv/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/libiconv/lib"
export CPPFLAGS="-I/usr/local/opt/libiconv/include"
    • 编译 php7
    mkdir php7
./configure --prefix=~/php7 --enable-fpm --enable-debug --with-iconv=/usr/local/opt/libiconv

    --prefix：编译好的文件存放的路径 --with-iconv：自己安装的libiconv路径，mac自带的与php用的不兼容，需要使用自己的

    • 修改Makefile文件

    查找 -liconv，删除 -liconv，结果长这样

    EXTRA_LIBS = -lresolv -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm /usr/local/opt/libiconv/lib/libiconv.dylib

    删除-liconv后，将/usr/local/opt/libiconv/lib/libiconv.dylib放在了最后

    • Make
    • Make install

    3、配置 Clion

    • 导入项目,如下图

    • CMakeLists 导入完成后，Clion会自动生成 CMakeLists.txt，这个要根据自己的路径改下，修改示例如下
    cmake_minimum_required(VERSION 3.15)
project(php_7_1_10)

set(CMAKE_CXX_STANDARD 14)

set(PHP_SOURCE ~/php-test/php-7.1.10)

add_custom_target(makefile COMMAND make && make install WORKING_DIRECTORY ${PROJECT_SOURCE_DIR})
    • 配置 profile

    右上角会生成如下的配置（重写CMakelist后是makefile）

    点击 Edit Configurations,配置如下：

    如何在 Mac 上用 Clion 调试 php7 源码

    • 1、创建了 CMake Applicaiton

    如果没有自己可以从template中创建

    • 2、target 选择CMakelist中自己配置的
    • 3、找到编译文件的路径，选择生成的二进制文件
    • 4、要运行的php文件路径参数

    -f ~/test/test.php

    • 5、工作目录，php测试文件的父目录即可

    ~/test/test.php

    • 6、最后点击apply，点击ok

    4、运行测试

    • 在如下的截图处（sapi->cli->php_cli.c）添加断点，这是命令行的main入口

    • 有的可能断点不成功，改下Debugger试试：

    preference->Build,Exexuction...->Toolchains->Debugger,有lldb和gdb切换下试试，这个和电脑上安装的软件有关

    • 运行成功的效果图如下：

    三、总结

    简单总结就是下载php源码，编译，然后配置clion，在clion 中debug。这种方式可以很方便的debug代码，debug过程中查看代码的跳转过程，提高阅读的效率。
