compilation - 在 CentOS 7 上编译 Shotdetect

Question

我正在将服务从 Debian 服务器迁移到 CentOS 7。

该服务需要 Shotdetect 命令( github 、 official site )。

尽管我遵循了所有步骤，但我无法让它在 CentOS 上运行:

安装需要的包

# yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

添加 线程 在 CMakeList 文件中的 TARGET_LINK_LIBRARIES 中，因为它会引发链接器错误中缺少 lpthread

编译 Shotdetect

# FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

我对上述错误进行了大量研究，但没有找到任何线索。

如何在 CentOS7 上成功编译 Shotdetect？

构建的二进制文件将在构建目录中，您可以移动到那里并执行

make install

使二进制系统范围更广。

你检查过这个类似的问题吗？ Linking libavcodec and libavformat: Undefined references

他们建议添加一些库:

-lswresample -lm -lz

祝你好运 :)
