ubuntu下编译VLC源码
1、从git上获得VLC源代码，当然你要确定你已经安装好了git：
git clone git://git.videolan.org/vlc.git
vlc源码还是挺大的，我下载下来一共是214M多
2、cd vlc
ls
AUTHORS compat doc m4 po THANKS
autotools configure.ac extras make-alias README
bin contrib include Makefile.am share
bindings COPYING INSTALL modules src
bootstrap COPYING.LIB lib NEWS test
3、./bootstrap
我在这里遇到一个问题：
./bootstrap
NOTE: GNU gettext appears to be missing or out-of-date.
Please install or update GNU gettext.
Also check if you have cvs, a dependency of autopoint.
Otherwise, you will not be able to build a source tarball.
==============================================================
generating modules/**/Makefile.am
.................................
+ autoreconf --install --force --verbose -I m4
./bootstrap: 78: ./bootstrap: autoreconf: not found
最开始的提示说需要更新或者安装GNU gettext，那就安装了gettext
sudo apt-get install gettext;
看下面的提示说autoreconf没有找到，那就安装一下吧：
sudo apt-get install autoconf automake libtool
安装好之后，再试一次：
./bootstrap
root@hlchen-Lenovo-Product:/home/share/mahang/vlc# ./bootstrap
NOTE: GNU gettext appears to be missing or out-of-date.
Please install or update GNU gettext.
Also check if you have cvs, a dependency of autopoint.
Otherwise, you will not be able to build a source tarball.

Successfully bootstrapped
看最开始还是提示说需要安装或者升级gettext，不知道这是啥原因，不管了，反正“Successfully bootstrapped”
4、安装vlc的依赖包：
sudo apt-get build-dep vlc
这也挺大，122M
5、编译
./configure
make
在make的时候出现错误：
/usr/bin/ld: /usr/local/lib/libavformat.a(allformats.o): relocation R_X86_64_32 against `ff_a64_muxer' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libavformat.a: could not read symbols: Bad value
在调用ffmpeg的库函数时出现错误，这是64位系统会出现的问题
已经提示解决方案了：recompile with -fPIC
重新编译ffmpeg
$CFLAGS="-fPIC" ./configure
make
make install
ldconfig
然后重新编译VLC
$CFLAGS="-fPIC" ./configure
make
make install
ldconfig
这样就对了
6、运行
./vlc

结合网上编译vlc的例子，我又安装了一个包：
sudo apt-get install checkinstall lua50
出现上述错误的原因是：我使用putty远程登录ubuntu，所以在我的windows终端无法显示，后来在ubuntu上运行./vlc，就会出现vlc的界面
$./vlc
7、安装
make install
可以卸载
make uninstall
make distclean
