Re: [Linux-gpib-general] RHEL 9 build failing

[dave p. <dpe...@gm...>]

Hi Chris,
It was fixed with this commit [778a98]
<https://sourceforge.net/p/linux-gpib/git/ci/778a98df97a2b89d401a54515bad3ce2346dd3af/>
,
The latest kernel divers are currently available in the
linux-gpib-git/linux-gpib-kernel directory of the git repo: git clone
https://dpe...@gi.../p/linux-gpib/git linux-gpib-git
I hope to cut a release for 4.3.7 which includes this fix in the next few
weeks.
cheers,
-Dave
