Compilation 在CentOS 7上编译Shotdetect

我正在将一个服务从Debian服务器迁移到CentOS 7服务器

该服务需要Shotdetect命令（，）

尽管我遵循了所有步骤，但无法在CentOS上运行：

编译ffmpeg

安装所需的软件包

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

在CMakeList文件的目标链接库中添加pthread，因为它在链接器错误中抛出一个lpthread missing

编译Shotdetect

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

5.陷入沉思

我对上述错误做了很多研究，但没有发现任何线索

如何在CentOS7上成功编译Shotdetect

感谢tryp，这里有一个工作的CMakelist文件： 构建的二进制文件将在构建的目录中，您可以移动到那里并执行

make install

---

使二进制系统更宽。

您检查过类似问题吗

他们建议添加一些库：

-lswresample -lm -lz

祝你好运：）

非常感谢。我将目标链接库更改为：目标链接库（${TARGET_NAME}${FFMPEG_LIBRARIES}${LIBXML2_LIBRARIES}${LIBXSLT_LIBRARIES}${GD_LIBRARIES}“pthread”“m”“z”“/root/FFMPEG_build/lib/libswresample.a”）和附加的缺失库太多（FFMPEG_LIBRARIES${FFMPEG_LIBRARIES}；/root/ffmpeg_build/lib/libswresample.a；/root/ffmpeg_build/lib/libx264.a；/lib64/libdl.so.2；/root/ffmpeg_build/lib/libfdk aac.a”）

make install

-lswresample -lm -lz
