As far as I know Arch Linux does not provide debugging versions of the libraries it uses. Package search: http://www.archlinux.org/packages/?sort=&q=libstdc%2B%2B&maintainer=&last_update=&flagged=&limit=50 Information about getting debugging info in Arch Linux: https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces It's not a huge problem now as I've managed to build libstdc++ with debug symbols. It is a little annoying though. Out of interest when you do build using --enable-libstdcxx-debug . How do you tell g++ to use the separately built debugging libraries? Dan.
