源码编译 7z

1. 目的

在 macOSX 电脑上，编译 7zip 的控制台应用程序 7zz， 复刻官方给的/homebrew 提供的 7zz 程序。

2. 下载源码

https://www.7-zip.org/a/7z2301-src.tar.xz

3. 查询编译规则描述文件

7zz 是控制台程序， 大概率是 main() 函数所在的源码 xxx.c/xxx.cpp 编译生成。

在名为 makefile 的文件里搜寻 7zz。

/Users/chris/Downloads/7z2301-src/CPP/7zip/Bundles/Alone2/makefile.gcc

PROG = 7zz

注意，不用 makefile 这个文件。 makefile 里描述的是 7zz.exe 生成过程， 是 windows 下的编译规则描述。貌似作者用的 vc6， 是个狠人。

4. 执行编译

cd /Users/chris/Downloads/7z2301-src/CPP/7zip/Bundles/Alone2
make -f makefile.gcc

查询编译出的控制台程序 7zz 放到哪里了：

➜  Alone2 find . -name "7zz"
./_o/7zz
