安装编译器和二进制工具
在源码根目录下执行prebuilts脚本，安装编译器及二进制工具。
bash build/prebuilts_download.sh
在源码根目录执行如下指令安装hb编译工具：
python3 -m pip install --user build/hb
使用build.sh脚本编译源码
- 进入源码根目录，执行如下命令进行版本编译。
x86系统编译：
./build.sh --product-name {product_name} --ccache
ARM系统编译：
./build.sh --product-name {product_name} --ccache --target-cpu arm64
说明： {product_name}为当前支持的产品名称，例如Hi3516DV300、rk3568等。
- 检查编译结果

=====build error=====
无论使用站点下载或者repo方式下载源码编译都出现这个错误，而别人编译是没有这个错误的。
怀疑是环境问题或源码不全，试下用如下方式看是否能解决：
1. 删除out目录，清除缓存 再次编译
rm -rf ./out
rm -rf ~/.ccache
hb clean
ccache -C
执行编译命令
2. 如果还报错
重新同步一下源码，并预编译 ：
repo sync -c -j16
repo forall -c ‘git lfs pull’
bash build/prebuilts_download.sh --skip-ssl
重复 1 里面的的步骤再次编译…
用了上述操作依然解决不了。
以前编译过4.1源码，环境应该是没问题的。
被搞郁闷了，别人编译都是一次过，没这问题。
按照错误提示ff_hwcontext_type_vulkan和by hwcontext.c进去源码分析错误原因，全局搜索ff_hwcontext_type_vulkan在哪里定义和使用了的，发现是在third_party/ffmpeg/libavutil/hwcontext_vulkan.c中定义，都有定义，为啥还会编译错误呢？看third_party/ffmpeg/libavutil/hwcontext.c：
static const HWContextType * const hw_table[] = {
#if CONFIG_CUDA&ff_hwcontext_type_cuda,
#endif
#if CONFIG_D3D11VA&ff_hwcontext_type_d3d11va,
#endif
#if CONFIG_LIBDRM&ff_hwcontext_type_drm,
#endif
#if CONFIG_DXVA2&ff_hwcontext_type_dxva2,
#endif
#if CONFIG_OPENCL&ff_hwcontext_type_opencl,
#endif
#if CONFIG_QSV&ff_hwcontext_type_qsv,
#endif
#if CONFIG_VAAPI&ff_hwcontext_type_vaapi,
#endif
#if CONFIG_VDPAU&ff_hwcontext_type_vdpau,
#endif
#if CONFIG_VIDEOTOOLBOX&ff_hwcontext_type_videotoolbox,
#endif
#if CONFIG_MEDIACODEC&ff_hwcontext_type_mediacodec,
#endif
#if CONFIG_VULKAN&ff_hwcontext_type_vulkan,
#endifNULL,
};
在这里看到ff_hwcontext_type_vulkan是在这里被使用的，链接找不到，说明CONFIG_VULKAN被配置成了1，但是ffmpeg的关于vulkan的功能又被禁用了，所以链接时找不到ff_hwcontext_type_vulkan？
找到CONFIG_VULKAN定义的地方，是在out/rk3568/gen/third_party/ffmpeg/include/config.h文件，在这里还可以看到Makefile：out/rk3568/gen/third_party/ffmpeg/include/config.mak
对比以前编译成功的4.1代码中的这2个文件发现，4.1配置如下，config.mak、config.h：
!CONFIG_VULKAN=yes
#define CONFIG_VULKAN 0
而我编译OH5.1这2个配置确实这样的：
CONFIG_VULKAN=yes
#define CONFIG_VULKAN 1
也对比同事编译的生成的配置也是和4.1的一样。搞不懂为啥我编译生成就变了呢，源码也没修改过，这应该就是一直编译出链接现这个错误的原因了。
那去分析ffmpeg配置。
third_party/ffmpeg/BUILD.gn是产生编译ninja编译文件的，其中调用//third_party/ffmpeg/ohos_config.sh进行配置ffmpeg。
action("gen_config_header") {if (current_os == "ios") {script = "//third_party/ffmpeg/ios_config.sh"} else if (current_os == "android" && host_os == "mac") {script = "//third_party/ffmpeg/android_mac_config.sh"} else {script = "//third_party/ffmpeg/ohos_config.sh"}if (!is_cross_platform_build) {if (ffmpeg_selected_platform == "aarch64") {print("third_party:ffmpeg # external_deps //third_party/musl:soft_libc_musl_static")external_deps = [ "musl:soft_libc_musl_static" ]}}
只能分析ohos_config.sh了，该文件里有2处定义FFmpeg配置的地方
第一处在文件18行，配置–disable-vulkan：
FF_CONFIG_OPTIONS="......--disable-vulkan......"
第二处在文件130行，没有配置–disable-vulkan。
尝试在该配置加入–disable-vulkan，然后编译，嗨，编译成功了。
至于为啥和别的配置一样却编译出现这个问题就搞不懂了，见鬼了。
