I'm unable to reply to thread ID 7137, which is the top hit when searching for this error. The error message was misleading in my case, as the symlink was broken, not recursive. The root problem was that libstdc++.a did not exist. On Fedora, it can be installed with `sudo dnf install libstdc++-static`. This appears to be a dependency of the BOINC wrapper, at least on Linux. On Debian and Ubuntu, I believe it is `sudo apt install build-essential` that ensures libstdc++.a is present.

I want to make sure this information is here for the people of the future who run into this error and keep things organized on this board. Thanks. :-)
