Compilation issue

[chaozhou5]

Hi,

Thanks a lot for your work. I am trying to compile the code and test some videos. However, I end up with the error shows below. After spend hours on this error, I still cannot pass it. Could you please help me and take a look at this error?

I working at ubuntu 14.04 with gcc 5.4.1, opencv 3.1.0, boost 1.54.0.1, cmake 3.2.2

Hi Jesse,

I still cannot figure it out. However, a new guess comes out. My FFmpeg is actually built with gcc 4.8. Even though I updated system gcc to version 5 +, it may still cause the problem. After reinstalling the whole FFmpeg, I will let you know the result.

Hi Chao, Thanks, So you think the problem is the version of gcc, I use the same version as you, maybe i think, let's figure it out. Jesse

[JesseYang-CQ]

Hi Chao, Does it work when you reinstalling the whole FFmpeg?

Hi Jesse,

Could you provide more detail about your reinstall process? I did the same thing but nothing changed. Thanks a lot.
