Ubuntu 9.04 x86:

vlad@vlad:~/bitcoin/bin/32$ ./bitcoind
./bitcoind: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11′ not found (required by ./bitcoind)

Anybody know what Bitcoin needs?

I don’t know.  Maybe someone with more Linux experience knows how to install the library it needs.

I built it on Ubuntu 10.04.  I hope that wasn’t a mistake.  Maybe it should have been built on an older version for more backward compatibility.  Is this a problem on Linux, that if you build on the latest version, then it has trouble working on older versions?  Is there any way I can downgrade to an older version of GCC on 10.04?

The 64-bit version shouldn’t be any faster than the 32-bit version, but it would be great if someone could do a side-by-side comparison of the two linux versions and check.  SHA-256 is a 32-bit algorithm and nothing in BitcoinMiner uses 64-bit at all.

We don’t need to bother with a 64-bit version for Windows.  32-bit programs work on all versions of Windows.  It’s not like Linux where the 64-bit OS wants 64-bit programs.

I’m also curious if it’s a little faster on linux than windows.

Do you think I should make the directories:
/bin32/
/bin64/
instead of
/bin/32/
/bin/64/
