ffmpeg在安装x264播放器的时候出现 ERROR: libx264 not found

[zz12006345]

我查了config.log 里面显示是

应该是编译这个问题的时候少了一个 -ldl 请问这个问题怎么解决？

[赵4老师]

在GUI配置相应项或makefile里面的gcc命令行中添加-ldl

[zz12006345]

makefile使用shell写的。。找不到把路径加在哪里怎么办。。。

仔细找，应该能找到。

./configure make su 输入root用户的密码 make install

解决了。。。只要在configure选项里面加上 --extra-libs=-ldl就可以了

[Frank范]

要在./configure 选项的哪个地方加上 --extra-libs=-ld 啊。我现在也出现这个问题了。怎么解决呢？

[Frank范]

./configure --extra-libs=-ld 直接用这个命令

[petersoap]

我是用楼主的方法，显示了Unknown option --extra-libs=-ldl, ignored请问这是为什么呢？
