基於vlc sdk的二次開發--環境搭建、編譯

前言

　　關於 搭建、編譯VLC，不同的平台有不同的方法，可以參考wiki。
　　其中在windows下編譯VLC有兩種方式，MSYS+MinGW和CygWin。通過測試，最后決定采用MSYS+MinGW搭建VLC編譯環境(多次測試， 通過且不需要額外的修改)。
　　詳細步驟請參考 wiki

注：文本編輯建議使用notepad2替代windows原有的notepad，並在保存文件前選擇“文件->行末符號->Unix（換行）”

　　搭建過程所需要的資料我沒上傳， 給個快照， 照着下載就是了。

VLC環境搭建

1. MinGW Setup
   運行tdm-gcc-4.5.2.exe， 然后Select "Create"，install to C:\MinGW（默認是C:\ MinGW32， 記得改成C:\ MinGW），keep default settings，afterwards check that C:\MinGW\bin is added to windows PATH （參考下圖 添加到末尾， 用分號分隔）
   
   解壓mingw-utils-0.3.tar， Extract contents to c:\MinGW
2. MSys Setup，運行MSYS-1.0.11.exe，然后：Go through the wizard and install to to default C:\Msys\1.0（默認是C:\msys\1.0， 記得改成C:\Msys\1.0）
   In the command window that opens, answer questions as follows:
   Accept Post Install: [y]
   MinGW Installed? : [y]
   path to MinGW: [c:/MinGW]
   接着安裝MSys Developer Toolkit，運行msysDTK-1.0.0.exe，然后Go through the wizard, keeping default values. （默認是C:\msys\1.0， 記得改成C:\Msys\1.0）
3. 將AutoTools and libcrypt，文件夾和Glib and PKG-CONFIG文件夾下面的所有包解壓到C:\Msys\1.0，添加set PKG_CONFIG_PATH=/win32/lib/pkgconfig到C:\MSys\1.0\msys.bat第一行。
4. Fix libtool search dirs
   Open C:\MSys\1.0\bin\libtool and change line 9926 by appending ' /mingw/lib' to the end of 'compiler_lib_search_dirs'. The line should then read : (注： 一定要用notepad2編輯文本，並保存為unix格式)

compiler_lib_search_dirs="/usr/lib /usr/lib /bin/../lib/gcc-lib/i686-pc-msys/2.95.3-1 /bin/../lib/gcc-lib /usr/lib/gcc-lib/i686-pc-msys/2.95.3-1 /bin/../lib/gcc-lib/i686-pc-msys/2.95.3-1/../../../../i686-pc-msys/lib /usr/lib/gcc-lib/i686-pc-msys/2.95.3-1/../../../../i686-pc-msys/lib /mingw/lib" 

5. 安裝lua
   Download the lua tools package from http://www.lua.org/ftp/lua-5.1.4.tar.gz
   Uncompress it in your home folder (C:\MSys\1.0\home\Administrator)
   run C:\MSys\1.0\msys.bat
   type the following commands:

cd /home/ Administrator /lua-5.1.4 
make mingw

This should produce lua.exe, luac.exe and lua51.dll in the src directory. Put these in your /bin with the commands:

cd src 
cp *.exe /bin
cp *.dll /bin
cd ..  

6. 安裝第三方庫（已提供最新版contrib-20110711-win32-bin-gcc-4.4.4-runtime-3.17-only.tar.bz2）， 解壓， 將usr目錄下面的win32文件夾拷貝到C:\Msys\1.0下

VLC編譯

1. 解壓vlc-1.1.11.tar
2. extract it to C:\MSys\1.0\home\ Administrator ，rename the vlc-1.1.11 dir to vlc
3. 編輯configure-msys.sh文件，添加--disable-upnp，類似於下圖：
   
   然后拷貝configure-msys.sh和configure-common.sh文件到C:\Msys\1.0\home\Administrator\vlc\extras\package\win32下。
4. Create a new file containing the single line:echoAdministrator
   and save it as C:\MSys\1.0\bin\whoami (without any extension)
   Modify configure.ac so that it doesn't call 'hostname -f' as follows:
   open C:\MSys\1.0\home\Administrator\vlc\configure.ac
   goto search button:
   change it as follows:
   old: AC_DEFINE_UNQUOTED(VLC_COMPILE_HOST, "hostname -f 2> /dev/null || hostname", [host which ran configure])
   new: AC_DEFINE_UNQUOTED(VLC_COMPILE_HOST, "hostname", [host which ran configure])
5. Build VLC
   The build is made exclusively from the command line, so if you closed the prompt at the LUA step, re-execute C:\MSy\1.0\msys.bat, then type the commands as mentioned Bootstrap

cd vlccp -v /win32/share/aclocal/* m4/cp -v /share/aclocal/* m4/PATH=/win32/bin:$PATH ./bootstrap
Configure

sh extras/package/win32/configure-msys.sh
Make (compile)

PATH=/usr/win32/bin:$PATH make -j4 (如果是四核的電腦， 否則相應修改)
make成功后如果想要生成sdk等文件夾， 可以輸入下面命令Create self-contained packages

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

make package-win32-base

(This will create a subdirectory named vlc-x.x.x with all the binaries "stripped" without any debugging symbols).

完！
