MediaInfo: Version `GLIBCXX_3.4.20' not found!

**Ashfaqur Rahman** · January 26th, 2015

I have installed Mediainfo 0.7.72 on Ubuntu 14.04 64 Bit. But when I run MediaInfo I get following error -

mediainfo-gui: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version GLIBCXX_3.4.20' not found (required by /usr/lib/libmediainfo.so.0)
mediainfo-gui: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: versionGLIBCXX_3.4.20' not found (required by /usr/lib/libzen.so.0)

What can I do?

Thanks!

I'm not sure what you installed but probably better you use a package built for 14.04

What do you mean by "Package Built"? Are you suggesting to compile from source?

I mean a package (.deb) that has been built for 14.04
You linked to the mediainfo page & said you installed 0.7.72 by some unmentioned, by you, means. I'm not inclined to guess what that was.

I have found that libstdc++.so.6 is actually a symbolic link to libstdc++.so.6.0.19 . I thought may be libstdc++.so.6.0.20 would solve my problem as the required version is GLIBCXX_3.4.20 . So I searched a little to know which version of GCC contains libstdc++.so.6.0.20 . Found this document which is indicating GCC 4.9.0 contains it. So I add this ppa and install GCC 4.9.0 which solved my problem.

Thanks by the way.
