tw1ddle / geometrize-installer Goto Github PK

This AppImage does not run on Ubuntu 14.04 which is the minimum requirement for inclusion in the AppImageHub central directory of available AppImages.

AppRun: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version CXXABI_1.3.11' not found (required by /run/firejail/appimage/.appimage-7254/AppRun)`

Reference:

This is because geometrize-installer was compiled on a distribution newer than Ubuntu 14.04, or a newer libstdc++ version was used than what comes with Ubuntu 14.04.

There are (at least) two solutions:

1. Compile on a stock Ubuntu 14.04 (without PPAs that install a newer libstdc++.so.6
2. Bundle libstdc++.so.6 inside the AppImage. In this case make sure to use https://github.com/darealshinji/AppImageKit-checkrt/

Background information:

Some projects require newer C++ standards to build them. To keep the glibc dependency low you can
build a newer GCC version on an older distro and use it to compile the project. This project however will now require a newer version of the libstdc++.so.6 library than available on that distro. Bundling libstdc++.so.6 however will in most cases break compatibility with distros that have a newer library version installed into their system than the bundled one. So blindly bundling the library is not reliable. While this is primarily an issue with libstdc++.so.6 in some rare cases this might also occur with libgcc_s.so.1. That's because both libraries are part of GCC. You would have to know the library version of the host system and decide whether to use a bundled library or not before the application is started. This is exactly what the patched AppRun binary from https://github.com/darealshinji/AppImageKit-checkrt/ does. It will search for usr/optional/libstdc++/libstdc++.so.6 and usr/optional/libgcc_s/libgcc_s.so.1 inside the AppImage or AppDir. If found it will compare their internal versions with the ones found on the system and prepend their paths to LD_LIBRARY_PATH if necessary.
