* status: reopened => needs_revision Comment: For review: https://github.com/azadi/tor-browser-build-1/tree/bug-25485 This is tested on Ubuntu 17.04 (`gcc 7`; newer) as well as Ubuntu 16.04 (`gcc 5.3.1`; older). To initiate the ABI check, we compare the installed `gcc` version with the bundled Tor Browser version `6.4.0`. If the installed version is more recent, we remove the bundled `libstdc++.so.6` from `Browser/TorBrowser/Tor`, which removes it from `LD_LIBRARY_PATH`. I am guessing this should suffice, or should we follow the symlink for libstdc++.so.6 and then compare the `CXXABI`, like for Ubuntu 17.04: {{{ $ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.24 | grep CXXABI_[[:digit:]] | sort -Vr | head -1 CXXABI_1.3.11 }}} and then compare it with the Tor Browser version: {{{ $ strings Browser/TorBrowser/Tor/libstdc++.so.6 | grep CXXABI_[[:digit:]] | sort -Vr | head -1 CXXABI_1.3.10 }}} which tells us the same thing and instead of comparing the version strings, we can compare this but I thought the `gcc` version is more direct. (As indicated in comment:14, we should consider using `rpath` as discussed in #13373 but I am not focusing on that for now.) -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25485#comment:15> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
