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

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:\MinGW\bin 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
MSys Setup，运行MSYS-1.0.11.exe，然后：Go through the wizard and install to to default C:\Msys\1.0（默认是C:\msys\1.0，记得改成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]

接着安装MSys Developer Toolkit，运行msysDTK-1.0.0.exe，然后Go through the wizard, keeping default values. （默认是C:\msys\1.0，记得改成C:\Msys\1.0）
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:\Msys\1.0，添加set PKG_CONFIG_PATH=/win32/lib/pkgconfig到C:\MSys\1.0\msys.bat第一行。
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"

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:\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 ..

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:\Msys\1.0下

VLC编译

解压vlc-1.1.11.tar
extract it to C:\MSys\1.0\home\ Administrator ，rename the vlc-1.1.11 dir to vlc
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:\Msys\1.0\home\Administrator\vlc\extras\package\win32下。
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])
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！
