Could the [url= https://boinc.berkeley.edu/wiki/Installing_BOINC#64_Bit_Considerations]wiki[/url] be updated to include lib32stdc++6 or lib32stdc++7. (I discovered that 7 is needed for the latest Ubuntu versions.) A user went to the wiki and followed the instructions but found everything crashing due to this missing. This with CPDN but I know at least one other project uses this.

Thanks.

Sorry, should have checked before posting, it seems the lib is in the list, though not lib32stdc++7 for the latest Ubuntu.

Following discussion with Dave, I've re-arranged this section to assume that current users are installing/running 64-bit versions of Linux by default, and thus the more urgent need is to install extra 32-bit libraries where needed. Previously (from about 2009), the presumption had been that the base system was 32-bit, and that 64-bit libraries were needed for compatibility.

Please check, and let me know if any further tweaks are necessary.

Certainly a great improvement. The real test will be whether anyone still gets tripped up by it. Nothing about getting the 32bit libs with Gentoo but as I said in our discussion, anyone who can install and run that distro is capable of find the answers themselves!
