基于vlc sdk的二次开发--环境搭建、编译

前言

　　关于 搭建、编译VLC，不同的平台有不同的方法，可以参考wiki。
　　其中在windows下编译VLC有两种方式，MSYS+MinGW和CygWin。通过测试，最后决定采用MSYS+MinGW搭建VLC编译环境(多次测试， 通过且不需要额外的修改)。
　　详细步骤请参考 wiki

注：文本编辑建议使用notepad2替代windows原有的notepad，并在保存文件前选择“文件->行末符号->Unix（换行）”

　　搭建过程所需要的资料我没上传， 给个快照， 照着下载就是了。

VLC环境搭建

1. MinGW Setup
   运行tdm-gcc-4.5.2.exe， 然后Select "Create"，install to C:MinGW（默认是C: MinGW32， 记得改成C: MinGW），keep default settings，afterwards check that C:MinGWin is added to windows PATH （参考下图 添加到末尾， 用分号分隔）
   
   解压mingw-utils-0.3.tar， Extract contents to c:MinGW
2. MSys Setup，运行MSYS-1.0.11.exe，然后：Go through the wizard and install to to default C:Msys1.0（默认是C:msys1.0， 记得改成C:Msys1.0）
   In the command window that opens, answer questions as follows:
   Accept Post Install: [y]
   MinGW Installed? : [y]
   path to MinGW: [c:/MinGW]
   接着安装MSys Developer Toolkit，运行msysDTK-1.0.0.exe，然后Go through the wizard, keeping default values. （默认是C:msys1.0， 记得改成C:Msys1.0）
3. 将AutoTools and libcrypt，文件夹和Glib and PKG-CONFIG文件夹下面的所有包解压到C:Msys1.0，添加set PKG_CONFIG_PATH=/win32/lib/pkgconfig到C:MSys1.0msys.bat第一行。
4. Fix libtool search dirs
   Open C:MSys1.0inlibtool 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编辑文本，并保存为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. 安装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:MSys1.0homeAdministrator)
   run C:MSys1.0msys.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. 安装第三方库（已提供最新版contrib-20110711-win32-bin-gcc-4.4.4-runtime-3.17-only.tar.bz2）， 解压， 将usr目录下面的win32文件夹拷贝到C:Msys1.0下

VLC编译

1. 解压vlc-1.1.11.tar
2. extract it to C:MSys1.0home Administrator ，rename the vlc-1.1.11 dir to vlc
3. 编辑configure-msys.sh文件，添加--disable-upnp，类似于下图：
   
   然后拷贝configure-msys.sh和configure-common.sh文件到C:Msys1.0homeAdministratorvlcextraspackagewin32下。
4. Create a new file containing the single line:echoAdministrator
   and save it as C:MSys1.0inwhoami (without any extension)
   Modify configure.ac so that it doesn't call 'hostname -f' as follows:
   open C:MSys1.0homeAdministratorvlcconfigure.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:MSy1.0msys.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 (如果是四核的电脑， 否则相应修改)
make成功后如果想要生成sdk等文件夹， 可以输入下面命令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！
