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 `checkrt` tool does. It will search for a bundled `libstdc++.so.6`
and `libgcc_s.so.1` library inside the AppImage or AppDir. If found it will
compare their internal versions with the ones found on the system (using dlopen())
and prepend their paths to `LD_LIBRARY_PATH` if necessary.
and `libgcc_s.so.1` library inside sub-directories next to it. If found it will
compare their internal versions with the ones found on the system and return a
path that can be prepended to `LD_LIBRARY_PATH`.
# Usage
Compile with `make -C src`. Inside your AppDir create the directory `usr/optional/`
Compile by running `make` inside the `src` directory.
Inside your AppDir create the directory `usr/optional/`
and put the binary `checkrt` inside there. Execute `usr/optional/checkrt --copy-libraries`
to bundle your system's `libstdc++.so.6` and `libgcc_s.so.1` libraries.
Use the provided AppRun script or write/modify your own. `checkrt` will either
