Subject: Workaround patch for missing Python3 transition of the old
|
|
(pre-USB-storage) photo memory card support (pcardext) as this part builds
|
|
in Python3 environments but with pointer-related warnings which are fatal
|
|
errors for Ubuntu's build servers. The patch silences the warnings but the
|
|
memory card support is dropped in Python3 environments. This patch is
|
|
supplied by the HPLIP upstream developers and will be replaced by a more
|
|
proper solution in the next upstream release of HPLIP (see LP: #1275353)
