周末折腾了好久，经过连续的出现问题，定位问题，解决问题，终于顺利编译通过了vlc的最新版本，中间尝试了多个版本的编译，比如vlc3.0.0，想着离2.x版本（2.x版本已经编译通过，可以参考：ubuntu平台，VLC/LibVLC交叉编译，生成win32版本，以及LibVLC增加录像接口）比较接近，应该容易编译通过，没成想也是一堆问题，其实主要还是版本导致的接口不对应问题，于是ubuntu的各种版本16.04x86,16.04x64,18.04x64等的尝试，终于看到了成功的果实，就像是中了大奖一样的心情。好吧，闲话不多说了，下面记录一下编译过程中的问题。
编译环境是在win7系统的虚拟机里面安装的ubuntu16.04x64 LTS版本，这个没什么好说的，不熟的可以自行搜索。因为vlc3.x版本需要gcc/g++支持c++11，所以gcc/g++的版本不能太低，可以通过命令gcc --version查看一下，我用的是4.9.3版本，大于4.9.0的版本都支持c++11。
官方的编译文档虽然说照着做肯定编译不过，但还是要参考一下的，最起码知道每一步该怎么去操作。
一、Mingw-w64环境
因为vlc主要用的还是32位版本，所以直接安装x86交叉编译环境：
sudo apt-get install gcc-mingw-w64-i686 g++-mingw-w64-i686 mingw-w64-tools
二、开发工具集
vlc编译过程所依赖的相关工具等，直接命令安装即可。
sudo apt-get update sudo apt-get install lua5.2 libtool automake autoconf autopoint make gettext pkg-config sudo apt-get install qt4-dev-tools qt5-default git subversion cmake cvs sudo apt-get install wine64-development-tools zip p7zip nsis bzip2 sudo apt-get install yasm ragel ant default-jdk protobuf-compiler dos2unix sudo apt-get install gperf flex bison
安装完成后，需要确认一下gettext的版本，gettext --version查看，vlc-3.x 要求 gettext>=0.19.8，但是 ubuntu 官方源只更新到了 0.19.7，如果版本低的话，手动安装一下即可。
wget ftp://ftp.gnu.org/gnu/gettext/gettext-0.19.8.tar.xz
tar -Jxvf gettext-0.19.8.tar.xz
cd gettext-0.19.8/
./configure --prefix=/usr
sudo make && sudo make install
三、安装第三方库
首先下载vlc3.0.4源码，建议手动去官方ftp目录下载，git获取的不一定是最新版本的。
解压源码之后，进入vlc目录，开始操作：
mkdir -p contrib/win32 cd contrib/win32 ../bootstrap --host=HOST-TRIPLET make fetch make
如果提示HOST-TRIPLET无法识别之类的问题，可以直接改成i686-w64-mingw32。
这里采用的是make fetch的方式，而没有采用make prebuilt的方式，是因为prebuilt的库文件比较旧，需要等待一点时间。
四、编译vlc
回到vlc目录，开始操作
./bootstrap mkdir win32 cd win32 export PKG_CONFIG_LIBDIR=$HOME/vlc/contrib/i686-w64-mingw32/lib/pkgconfig export CFLAGS="-O2" export CXXFLAGS="-O2" ../configure --host=i686-w64-mingw32 其中遇到了以下几个问题：
1、cp ../../contrib/tarballs/dxgi1_2.idl dxgi12 && cd dxgi12 && patch -fp1 < ../../../contrib/src/d3d11/dxgi12.patch patching file dxgi1_2.idl mkdir -p -- "/home/vlc/vlc/contrib/i686-w64-mingw32/include/" i686-w64-mingw32-widl -DBOOL=WINBOOL -I/usr/include/wine/windows/ -h -o /home/vlc/vlc/contrib/i686-w64-mingw32/include/dxgi1_2.h dxgi12/dxgi1_2.idl dxgi12/dxgi1_2.idl:43: error: syntax error, unexpected aKNOWNTYPE, expecting tIMPORT ../../contrib/src/d3d11/rules.mak:63: recipe for target '/home/vlc/vlc/contrib/i686-w64-mingw32/include/dxgi1_2.h' failed make: *** [/home/vlc/vlc/contrib/i686-w64-mingw32/include/dxgi1_2.h] Error 1解决方案： sudo apt-get install wine64-development-tools 修改 contib\src\d3d9\rules.mak 中的IDL_INC_PATH = /usr/include/wine/windows/ 为 IDL_INC_PATH = /usr/include/wine-development/windows/ 修改 contrib\src\d3d11\rules.mak 中的IDL_INC_PATH = /usr/include/wine/windows/ 为 IDL_INC_PATH = /usr/include/wine-development/windows/
2、versioninfo.rc错误：
i686-w64-mingw32-windres: versioninfo.rc.in:21: syntax error i686-w64-mingw32-windres: preprocessing failed. Makefile:1224: recipe for target 'versioninfo.lo' failed make[2]: *** [versioninfo.lo] Error 1 make[2]: Leaving directory '/home/d/vlc-3.0.0/contrib/win32/gcrypt/src' Makefile:487: recipe for target 'install-recursive' failed make[1]: *** [install-recursive] Error 1 make[1]: Leaving directory '/home/d/vlc-3.0.0/contrib/win32/gcrypt' ../../contrib/src/gcrypt/rules.mak:72: recipe for target '.gcrypt' failed make: *** [.gcrypt] Error 2
解决方案： 修改 contrib/win32/gcrypt/configure.ac 第42行
修改前：m4_esyscmd([git rev-parse --short HEAD | tr -d '\n\r'])) 修改后：m4_esyscmd([printf %x $(wc -l < debian/changelog)]))
3、../../contrib/src/protobuf/rules.mak:24: recipe for target '.protobuf' failed make: *** [.protobuf] Error 2解决方案： 通过protoc --version可查看protobuf版本，需升级protobuf到3.0.1版本，这样和contribute里的版本保持一致，避免后面再次报错
https://github.com/protocolbuffers/protobuf/releases/ （此地址可能需要FQ，我会把文件放到网盘里）
configure完成后，执行sudo make，报了以下几个错误：
1、In file included from ../../modules/access/dshow/dshow.cpp:52:0: ../../modules/access/dshow/access.h:33:24: fatal error: wrl/client.h: No such file or directory compilation terminated.
解决方案： 从 https://forum.videolan.org/viewtopic.php?f=32&t=137580&p=453684&hilit=roapi.h%3A80%3A25#p453684 下载 mingw-w64-mingw-w64 将mingw-w64-mingw-w64/mingw-w64-headers/include下的 wrl 文件夹整个拷贝到编译包的contrib/i686-w64-mingw32/include下

4、/home/zqf/vlc/contrib/i686-w64-mingw32/include/versionhelpers.h: In function ‘IsWindows8Point1OrGreater’: /home/zqf/vlc/contrib/i686-w64-mingw32/include/versionhelpers.h:70:45: error: ‘_WIN32_WINNT_WINBLUE’ undeclared (first use in this function) return IsWindowsVersionOrGreater(HIBYTE(_WIN32_WINNT_WINBLUE), LOBYTE(_WIN32_WINNT_WINBLUE), 0); ^ /home/zqf/vlc/contrib/i686-w64-mingw32/include/versionhelpers.h:70:45: note: each undeclared identifier is reported only once for each function it appears in /home/zqf/vlc/contrib/i686-w64-mingw32/include/versionhelpers.h: In function ‘IsWindowsThresholdOrGreater’: /home/zqf/vlc/contrib/i686-w64-mingw32/include/versionhelpers.h:74:45: error: ‘_WIN32_WINNT_WINTHRESHOLD’ undeclared (first use in this function) return IsWindowsVersionOrGreater(HIBYTE(_WIN32_WINNT_WINTHRESHOLD), LOBYTE(_WIN32_WINNT_WINTHRESHOLD), 0);解决方案：
修改拷贝到contrib/i686-w64-mingw32/include/下面的versionhelpers.h文件，将_WIN32_WINNT_WINBLUE和_WIN32_WINNT_WINTHRESHOLD改成_WIN32_WINNT_WIN8
引申：下面是 Windows 10 版 SDKDDKVer.h（它对每个版本的 Windows 的值进行编码）中的行：
// // _WIN32_WINNT version constants //
#define _WIN32_WINNT_NT4 0x0400 // Windows NT 4.0 #define _WIN32_WINNT_WIN2K 0x0500 // Windows 2000 #define _WIN32_WINNT_WINXP 0x0501 // Windows XP #define _WIN32_WINNT_WS03 0x0502 // Windows Server 2003 #define _WIN32_WINNT_WIN6 0x0600 // Windows Vista #define _WIN32_WINNT_VISTA 0x0600 // Windows Vista #define _WIN32_WINNT_WS08 0x0600 // Windows Server 2008 #define _WIN32_WINNT_LONGHORN 0x0600 // Windows Vista #define _WIN32_WINNT_WIN7 0x0601 // Windows 7 #define _WIN32_WINNT_WIN8 0x0602 // Windows 8 #define _WIN32_WINNT_WINBLUE 0x0603 // Windows 8.1 #define _WIN32_WINNT_WINTHRESHOLD 0x0A00 // Windows 10 #define _WIN32_WINNT_WIN10 0x0A00 // Windows 10
make完成后，进行打包生成windows相关文件的操作：
make package-win-common
第一次打包成功，无任何错误报出，第二次报出以下错误：
cp: cannot stat '../share/hrtfs': No such file or directory Makefile:2389: recipe for target 'package-win-common' failed make: *** [package-win-common] Error 1
解决方案：在vlc3.0.4根目录的share文件夹下面手动建一个空文件hrtfs
会在win32下面生成vlc-3.0.4文件夹，然后
cd vlc-3.0.4 find . -name "*.dll" -type f | xargs -i strip --strip-all {} 去掉调试信息
拷贝整个vlc-3.0.4文件夹到本地测试，播放文件和网络流等一切正常。
最后分享一下用到的几个文件
