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

../../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
2、/usr/share/mingw-w64/include/roapi.h:60:33: error: ‘Windows::Foundation::Initalize’ declared as an ‘inline’ variable

Makefile:25261: recipe for target 'access/dshow/dshow.lo' failed
make[4]: *** [access/dshow/dshow.lo] Error 1
解决方案:
将mingw-w64-mingw-w64/mingw-w64-headers/include中的roapi.h dwrite.h dwrite_1.h dwrite_2.h versionhelpers.h等文件拷贝到contrib/i686-w64-mingw32/include/,这样可以避免后面出现的许多错误

解决方案:安装protobuf3.0.1版本,上面已安装的话,就应该不会报这个错误了
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’:

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
