ubuntu20.04交叉编译vlc3.0.21 x64 windows版本

1.下载源码：Index of /pub/videolan/vlc/3.0.21/

2.下载contrib:

http://download.videolan.org/pub/videolan/contrib/x86_64-w64-mingw32/vlc-contrib-x86_64-w64-mingw32-20240625.tar.bz2

3.安装依赖

sudo apt-get update -qq
#官网说的依赖
sudo apt-get install -qqy \git wget bzip2 file libwine-dev unzip libtool libtool-bin libltdl-dev pkg-config ant \build-essential automake texinfo yasm p7zip-full autopoint \gettext cmake zip wine nsis g++-mingw-w64-i686 curl gperf flex bison \libcurl4-gnutls-dev python3 python3-setuptools python3-mako python3-requests \gcc make procps ca-certificates \openjdk-11-jdk-headless nasm jq gnupg \meson autoconf liblua5.2:i386 liblua5.2-dev#博客说的依赖，反正都安装一遍
apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 mingw-w64-tools
apt-get install lua5.2:i386 libtool automake autoconf autopoint make gettext pkg-config qt4-dev-tools qt5-default git subversion cmake cvs wine64-development-tools libwine-dev zip p7zip nsis bzip2 yasm ragel ant default-jdk protobuf-compiler dos2unix

4.安装contrib

mkdir contrib/win32 && cd contrib/win32#将下载好的contrib文件拷贝到contrib/win32下
#或者用命令下载：wget http://download.videolan.org/pub/videolan/contrib/x86_64-w64-mingw32/vlc-contrib-x86_64-w64-mingw32-20240625.tar.bz2tar -xjf vlc-contrib-*.tar.bz2
../bootstrap --host=x86_64-w64-mingw32
make prebuilt

5.返回源码根目录，配置编译环境

cd /home/name/vlc-3.0.18
./bootstrap
mkdir win32 && cd win32

6.编写build.sh，内容如下：

export PKG_CONFIG_LIBDIR="../contrib/x86_64-w64-mingw32/lib/pkgconfig"
export GIT_DISCOVERY_ACROSS_FILESYSTEM=1
../configure \--host=x86_64-w64-mingw32 \--disable-static \--enable-shared \--disable-chromecast \--with-win32-sdk=../contrib/x86_64-w64-mingw32

7.执行./build.sh文件，有报错一般是缺组件，apt安装就是了

8.执行make -j4编译，遇到错误就查，参考：修改vlc 3.0.21源码解决directx_va.c:69:41: error: ‘FF_PROFILE_AV1_HIGH’ undeclared here (not in a function)-CSDN博客

如果是/gettext-runtime/intl/printf.c:138: undefined reference to `__imp___acrt_iob_func'，就是minGW版本错误，那么需要更换ubuntu版本，我一开始是18.04，后面折腾问题越来越多，果断换ubuntu20.04，果然没有这些错误了。

还有不要在共享文件里编译，不要git clone费劲下载源码和contrib依赖，直接浏览器下载，不然数不清的坑等着你。

9.执行make package-win-common，会生成一个vlc3.0.21的文件夹，要的东西都在里面了。
