Ubuntu18.04编译vlc-3.0.10
最近要整一些视频操作，选择了vlc-qt。奈何使用vlc-qt需要先编译vlc。
1、首先下载vlc
访问官网https://www.videolan.org/vlc/ 选择要下载的版本 ，当然也可以直接下载http://get.videolan.org/vlc/3.0.10/vlc-3.0.10.tar.xz
将源码下载到本地后，开始尝试着编译，为什么说是尝试，因为会遇到各种各样的报错。
2、尝试配置
cd到源码的主目录，执行命令
./bootstrap
./configure
出现报错：configure: error: Could not find lua. Lua is needed for some interfaces (rc, telnet, http) as well as many other custom scripts. Use --disable-lua to ignore this error.
解决方案：根据./configure命令提示，下载对应的lua，我这里以下执行命令：
sudo apt install lua5.2
sudo apt install lua5.2-dev
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
再次执行./configure
出现报错：configure: error: Missing libav or FFmpeg. Pass --disable-avcodec to ignore this error.
解决方案：这里有两种解决方案。
方案（1） 执行命令： ./configure --prefix=/usr/local/vlc --disable-avcodec .让其直接忽略这个错误即可。
方案（2）执行命令：sudo apt install libavcodec-dev 。
我是采用第二种方案。
再次执行./configure
出现报错：configure: error: No package 'libswscale' found. Pass --disable-swscale to ignore this error. Proper software scaling and some video chroma conversion will be missing.
解决方案：这里有两种解决方案。
方案（1） 执行命令： ./configure --prefix=/usr/local/vlc --disable-avcodec --disable-swscale .让其直接忽略这个错误即可。
方案（2）执行命令：sudo apt install libswscale-dev 。
我是采用第二种方案。
再次执行./configure
出现报错：configure: error: No package 'liba52' found. Pass --disable-a52 ........(此处省略好多字母)
解决方案：这里有两种解决方案。
方案（1） 执行命令： ./configure --prefix=/usr/local/vlc --disable-avcodec --disable-swscale --disable-a52 .让其直接忽略这个错误即可。
方案（2）执行命令：sudo apt install liba52-dev 。
我是采用第二种方案。
再次执行./configure
出现报错：configure: error: No package 'libpostproc' found. Pass ........(此处省略好多字母)
解决方案：
执行命令：sudo apt install libpostproc-dev 。
再次执行./configure
出现报错：configure: error: Package requirements (xcb-shm) were not met:No package 'xcb-shm' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables XCB_SHM_CFLAGS and XCB_SHM_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
解决方案：
sudo apt install pkg-config
sudo apt install autoconf
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
执行./bootstrap
出现报错：
NOTE: autopoint (GNU gettext-tools) appears to be missing or out-of-date.
Please install or update GNU gettext tools.
Otherwise, you will not be able to build a source tarball.
==========================================================================
autoreconf: Entering directory `.'
autoreconf: running: true --force
autoreconf: running: aclocal -I m4 -I m4 --output=aclocal.m4t
Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 326.
autoreconf: failed to run aclocal: No such file or directory
解决方案：sudo apt install automake
再次执行./bootstrap
出现报错：
NOTE: autopoint (GNU gettext-tools) appears to be missing or out-of-date.
Please install or update GNU gettext tools.
Otherwise, you will not be able to build a source tarball.

autoreconf: failed to run libtoolize: No such file or directory
autoreconf: libtoolize is needed because this package uses Libtool
解决方案：sudo apt install libtool
重新执行./bootstrap，则可以成功通过

重新执行命令：./configure --prefix=/usr/local/vlc
出现报错：
configure: error: Package requirements (xcb-shm) were not met:
No package 'xcb-shm' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables XCB_SHM_CFLAGS
and XCB_SHM_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
解决方案：sudo apt install libxcb-shm0-dev
重新执行命令：./configure --prefix=/usr/local/vlc
出现报错：
configure: error: Package requirements (xcb-xv >= 1.1.90.1) were not met:
No package 'xcb-xv' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables XCB_XV_CFLAGS
and XCB_XV_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
解决方案：sudo apt install libxcb-xv0-dev
重新执行命令：./configure --prefix=/usr/local/vlc
出现报错：configure: error: No package 'alsa' found. alsa-lib 1.0.24 or later required. Pass --disable-alsa to ignore this error.
解决方案：sudo apt install libalsa-ocaml-dev
再次执行命令./configure --prefix=/usr/local/vlc，配置成功
执行命令：
make -j4
sudo make install
vlc就编译安装完成了！！！！
