Haiku shredder 1 hrev57937+113 Sep 12 2024 21:59 x86_64 x86_64 Haiku
(Haiku R1/beta5)
>Description:
Vim, specifically editors/vim-share, fails to link on Haiku because it is missing -lgnu for the xattr family of functions. Supplied patch adds it. Haikuports does the same thing.
>How-To-Repeat:
Install Haiku on a spare machine, bootstrap pkgsrc, try to build editors/vm
>Fix:
