Rpcs3: AppImage fails to run, GLIBCXX_3.4.21 not found

[probonopd]

Currently the mimimum system requirement for applications listed in the AppImageHub central directory of available AppImages is Ubuntu 14.04 trusty, the oldest still-supported LTS version.

However, the RPCS3 AppImage fails to run since it needs a newer libstdc++ than what comes with Ubuntu 14.04 trusty. This results in a GLIBCXX_3.4.21 not found error.

AppRun: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /run/firejail/appimage/.appimage-7327/AppRun)
/run/firejail/appimage/.appimage-7327/AppRun: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /run/firejail/appimage/.appimage-7327/AppRun)

This could be solved by compiling RPCS3 on a stock Ubuntu 14.04 trusty system, while making sure that no never libstdc++ version is installed on the build system than what comes with the system by default.

Alternatively, libstdc++ could be bundled inside the AppImage; in this case, care must be taken not to load this bundled libstdc++ version if a newer version of it is already present on the system, or else it will crash.

Does this still occur? I'll look into fixing this, but I can't reproduce it in my trusty virtualbox vm.

Yes, libstdc++.so.6: version 'GLIBCXX_3.4.20' not found still persists. To check, run it on a Ubuntu 14.04 Live ISO.

Alright, the latest build now works on Ubuntu Trusty.
I was looking at your script, and you can get the latest build of rpcs3 using something like
https://rpcs3.net/cdn/builds/$(curl -s https://rpcs3.net/cdn/builds/latest-llvm.txt)

Thanks @hcorion is there any chance you could add permalinks? Reason is that we can't have bash scripts in the data files for each application (only links).

Yes, will add permalink for latest Linux build. latest-llvm.txt is used on internal scripts and wasn't meant for end user usage, although it can be accessed by anyone who wants to fetch the latest filename.

I've added permalink for the latest Linux AppImage

wget
wget --content-disposition https://rpcs3.net/latest-appimage

curl
curl -JLO https://rpcs3.net/latest-appimage
