MSYS2环境使用记录

1. MSYS2官方网站

Wiki: https://sourceforge.net/p/msys2/wiki/Home/

Home: http://msys2.github.io/

Sourcefore Home: https://sourceforge.net/projects/msys2/

MSYS2-packages: https://github.com/Alexpux/MSYS2-packages

MINGW-packages: https://github.com/Alexpux/MINGW-packages

2. 国内源配置

使用MSYS2官方的源,在执行软件包的下载安装时一般很是的慢,常常连接被重置,若是有一个国内的安装镜像源的话,那么速度是很是快的.如今什么东西都有国内的镜像了,好比操做系统镜像,Eclipse镜像,就连Google的Andriod stdio IDE的更新都能找到国内的源....这说明咱们国内的技术愈来愈注重基础环境的构建,这是一种良性的软件开发生态,很是高兴.

在MSYS2的官方网站上,没有找到全部的镜像源的全部记录,只能经过搜索引擎慢慢的查找, 首先是MSYS2-packages中带的一个pacman-mirrors, 路径为https://github.com/Alexpux/MSYS2-packages/tree/master/pacman-mirrors 这个目录中指向的三个文件也就是咱们MSYS2默认使用的源.

在https://gist.github.com/elvisw/cc00088e9c8fd1c83aca 中有几个源,目前在网络上搜索类似度比较高的也就是这几个. mirrorlist.mingw32

而中国科学技术大学的镜像源配置说明在https://lug.ustc.edu.cn/wiki/mirrors/help/msys2 可是按照文章中的指示:

pacman 的配置

编辑 /etc/pacman.d/mirrorlist.mingw32 ，在文件开头添加：

  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MINGW/i686
编辑 /etc/pacman.d/mirrorlist.mingw64 ，在文件开头添加：

  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MINGW/x86_64
编辑 /etc/pacman.d/mirrorlist.msys ，在文件开头添加：

  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MSYS2/$arch
而后执行 pacman -Sy 刷新软件包数据便可。

去配置镜像源,发现根本就不会起做用,一度让我认为这个源已经失效, 今天意外地发现,目前的镜像源应该配置为下面的内容才是合法有效的:

mingw32: Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686
mingw64: Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64
msys   : Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch

在这篇文章中提到如何搭建MSYS2的镜像源,摘录以下:

Hi,

1. Where do I download "the repository"?

From http://repo.msys2.org/mingw using curl or wget for example

2. What do I need to do to configure pacman to use my mirror rather than the main repo?

Edit /etc/pacman.conf and define a new repository as explained in pacman.conf manpage. The new repository can be local or remote depending on your needs.

For a remote server, just setup an HTTP server serving the content of the directory where you downloaded packages (step. 1).

Packages must be indexed using the tool repo-add, see the manpage again.

That's all!

3. configure.ac: error: possibly undefined macro: AC_MSG_ERROR

最近在MSYS2中的MINGW64环境中编译一个软件包的时候,遇到一个以下的错误:

$ ./autogen.sh
Running autoreconf --verbose --install --force
autoreconf: Entering directory `.'

还有好多,基本上提到的方法都没有解决这个问题, 既然解决不了"ERROR",我想先把"WARN"解决了吧,更换关键字,搜索到[Buildroot] [PATCH 1/1] systemd: fix AM_PATH_LIBGCRYPT not found

This patch installs a copy of libgcrypt.m4 from the libgcrypt source tarball to systemd m4 directory.

Libgcrypt uses a custom m4 macro and not pkg-config to check if the development files are available. Though libgcrypt support is optional in systemd, this macro should be available whenever autoreconf is used, otherwise the re-configuration will fail with:

configure.ac:616: warning: macro 'AM_PATH_LIBGCRYPT' not found in library

The call to autoreconf is required, as it is needed by the patch which solves the ln --relative issue.

提示要安装libgcrypt,搜索libgcrypt库

$ pacman -Sl | grep libgcrypt
mingw32 mingw-w64-i686-libgcrypt 1.7.3-1
mingw64 mingw-w64-x86_64-libgcrypt 1.7.3-1
msys libgcrypt 1.6.4-1 [已安装]
msys libgcrypt-devel 1.6.4-1

这里使用的MINGW64,因此安装mingw-w64的库

$ pacman -S mingw-w64-x86_64-libgcrypt

安装完成后,再次执行./autogen.sh

$ ./autogen.sh
Running autoreconf --verbose --install --force
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4

顺利经过,困扰在心中的烦恼终于消失,可是感受对Linux的automake,autoconf,libtool,m4,autogen等工具了解还不是很是深刻,致使遇到问题老是搜索啊搜索.
