Windows 搭建msys2+mingw32開發環境，編譯安裝vlc

介紹
這個就不說了
安裝Windows工具
我使用了nodepad++和winrar，設定如下：
1. 顯示行尾符：檢視->顯示符號->顯示行尾符
2. 設定為unix行尾符：編輯->文件格式轉換->轉為UNIX格式2. 設定為unix行尾符：編輯->文件格式轉換->轉為UNIX格式
安裝msys2和gcc
1. msys2的安裝詳見其官網，我這裡碰到一個問題：在執行pacman -Su的時候提示本地簽名錯誤
  
  執行以下命令（我使用管理員身份執行，未驗證普通使用者是否可以）：
```
pacman-key --init
pacman-key --populate msys2
 
```
2. 我為了方便，同時進行了兩者的安裝，在執行pacman -S git subversion cvs automake autoconf libtool m4 make gettext pkg-config mingw-w64-i686-lua findutils mingw-w64-i686-headers yasm patch的時候，mingw-w64-i686-headers.git提示檔案已存在，去掉這個倉庫重新執行。
3. 全部安裝完成後，檢測一下，文件提到了Restart:Exit MSys2, run autorebase.bat and re-run MSys2 from mingw32_shell.bat
  
  ，我理解的是退出MSys2，執行autorebase.bat，然後從mingw32_shell.bat再次執行MSys2，可是我特麼的找不到mingw32_shell.bat啊。。。。
獲取vlc原始碼（有兩點需要注意）
1. 行尾符保證原來的就好，所以在Windows平臺需要設定一下。官網使用了git config core.autocrlf=false，我這裡提示無效鍵名，我執行了git config ---global core.autocrlf false。
2. Windows使用者名稱中不能有空格，vlc不支援
獲取預編譯第三方依賴庫
1. 這裡碰到一個問題：which: no protoc in ......
  
  ，頭疼

一開始提到的官方文件有時候打不開，這裡附上全文：

Introduction

MSys2 is a helper environment for MinGW, the compiler chain for Windows based on GCC.

It can build VLC natively on Microsoft Windows. However, VideoLAN developers strongly recommend cross-compiling VLC from Linux, which is faster and easier. If you decide to stick to the MSYS method, you are on your own. Should you encounter any problem and ask for help, expect to be told to cross-compile.

Either way, VLC is a complex program with many dependencies, most of which are obtained/built through the command line interface. Therefore, experience with the POSIX command line (i.e. the Unix shell) is required. Time, patience and persistence are indispensable. The entire process outlined below should take at the very least 4 hours. Experience show that mistakes are common, especially with beginners, so you might need to make multiple attempts.

Install Windows tools

Text editor

To edit unix-style text documents you need a suitable editor: Notepad is not enough.

Use notepad2. You can set File - Line endings - Default to "Unix (LF)", but it always saves opened files in the ending style they have.

Or use notepad++.

Unzip Utility (7-zip)

Files to downloaded will have to be uncompressed. Some of them use Unix originated formats (.tar.gz, .tar.bz2, .tar.lzma), you will then need a versatile unzipping utility.

A recent version of 7-zip is therefore strongly advised.

Install MSys2 and GCC

Install MSys2 from http://msys2.github.io/

We recommend to use the 32bits version.

Let the default, and run the command line.

Tools

Install the autotools suite:

 pacman -S git subversion cvs automake autoconf libtool m4 make gettext pkg-config mingw-w64-i686-lua findutils  mingw-w64-i686-headers yasm patch

gcc

Download gcc from: mingw-w64.

Unzip it to C:\MSys2\

Restart

Exit MSys2, run autorebase.bat and re-run MSys2 from mingw32_shell.bat

Check GCC

Run

gcc -v

And check that it says

Thread model: win32
gcc version 4.9.2 (i686-win32-sjlj-rev0, Built by MinGW-W64 project)

Get VLC sources

Git

YOU MUST keep the native line-endings of the repo.

git config core.autocrlf=false

Clone the git repo

git clone git://git.videolan.org/vlc.git

Nota Bene: ensure your Windows user name does not contain spaces so that the cloning folder of VLC will not not have spaces in it.

Get precompiled 3rd party libraries

cd vlc/contrib
mkdir win32 && cd win32
../bootstrap --build=i686-w64-mingw32
make prebuilt

Note: check that all is well with moc -v

Build VLC

Bootstrap

In VLC root folder, do:

./bootstrap

Configure

mkdir win32
cd win32
sh ../extras/package/win32/configure.sh --host=i686-w64-mingw32 --disable-nls

Note: If you want any custom options, like "--disable-lua" or anything of that nature, you can append them.

Make (compile)

make -j4

Note: If your <username> starts with the "u" or "x" character, change C:\MSys\1.0\home\<username>\config.h and double all backslashes in VLC_COMPILED_BY constant.

Create packages

Run VLC

Once the compilation is done, build self-contained VLC packages with one of the following "make" commands:

make package-win-common

This will create a subdirectory named vlc-x.x.x with all the binaries with debugging symbols. You can run ./vlc.exe from there.

Create proper packages

make package-win32-zip

(Same as above but will package the directory in a zip file).

make package-win32-exe

(Same as above but will also create an auto-installer package. You will need to have NSIS installed in its default location for this to work).
