Build Static Lib Package Under ArchLinux

通常情况下，Arch 下的包不像 RHEL 系那样有单独的静态库 (RHEL系命名风格一般是 libXXX-static)，但并不是说Arch下面的包都没有静态库，这个得看情况。比如 /lib/libresolv.a， /lib/librt.a 属于 GNU libc （glibc包）, /lib/libstdc++.a 属于 gcc 包。

以 libgit2 包为例，ArchLinux 源里是没有提供静态库的。相对的, Ubuntu 有提供静态库的 package, 甚至连 ArlpineLinux 也有提供。 Fedora 下的 libgit2 好像没有静态lib。Ubuntu 是直接放在 libgit2-dev 包里（/usr/lib/x86_64-linux-gnu/libgit2.a）

由于Arch源里其实已经有libgit2了，因此我们对 PKGBUILD 文件作做修改即可编译相应的静态库。

首先我们安装 asp, 如果没有安装的话： sudo pacman -S --needed asp

然后获取Arch构建源码： asp checkout libgit2

修改之后执行 makepkg 即可。

如果不用asp, 也可以手动用git clone源码。

进入包页面 https://archlinux.org/packages/extra/x86_64/libgit2/ 然后点击 Source Files 即可查看源码。然后我们就跳到了 https://github.com/archlinux/svntogit-packages/tree/packages/libgit2/trunk

clone仓库然后 checkout 到 packages/libgit2/trunk 分支即可。（对于 Arch 这种用分支来存包源码的行为，老灯表示有点迷啊，可能跟它从svn转过来有关？）
