Use 14.04 (trusty) or older

Interesting project. Please use 14.04 (trusty) or older as the basis for your AppImages; this way, they can run on older distributions, too. Thanks!

Ubuntu Trusty has outdated packages for CMake and GCC. Resolved it by adding custom PPA-s, however when trying to run the AppImage on plain Ubuntu Trusty VM it will fail with the following error:

/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by ./Plex_Media_Player_20170705_044db29_x86-64.AppImage)

Using new version of GCC (minimum GCC 4.9 is required to compile the code) will increase the dependency for libstdc++ to version supported by it. Of course it will not be present on plain Trusty system.

Ubuntu 14.04 has reached its end of life. Closing as it will not be used as the base for the AppImage.

Correct, 16.04 is now the new baseline.
