I did a pacman -Syu and upgraded all of my packages. However, since doing this, bitcoind no longer works at all. I get an undefined symbol error that appears to be boost related
[earlz@EarlzWork ~]$ bitcoind --help bitcoind: symbol lookup error: bitcoind: undefined symbol: _ZN5boost10filesystem6detail9copy_fileERKNS0_4pathES4_NS0_11copy_option9enum_typeEPNS_6system10error_codeE
I can confirm this.
Please open a bug report.
Very similar bug report here: https://bugs.archlinux.org/task/38187
Please try boost-libs-1.55.0-4 which I just pushed.
Fixed for me, thanks :-)
