A list of open issues in porting software to run on GNU/Hurd systems. This list also includes toolchain-level items, items that are either already solved in Debian GNU/Hurd systems (tagged fixed_in_debian) or being worked around, so if you're out for working on application-level porting issues, then perusing through the list of Debian packages that need porting may be better.
These pages are tagged as having a stable URL. That is, they're linked to from external pages, and their locations should not be changed needlessly.
