[screen-devel] Commit d340b02c (Do not link against libelf.) has been accidentially(?) reverted by a8dc1fb5 (Rename configure.in to configure.ac)

[Axel Beckert]

Hi,

while investigating why screen still uselessly links against libelf
despite commit d340b02c ("Do not link against libelf.") from 2014
(noticed by Sven Joachim, Cc'ed, c.f. https://bugs.debian.org/903818),
I noticed that following:

Commit a8dc1fb5 ("Rename configure.in to configure.ac") from 2015
silently reverted the above mentioned commit and hence reintroduced
the useless linking against libelf. (It also introduced another change
not mentioned in the commit message, which is removing the line
"AC_PREREQ(2.60)". But I assume that's just another ancient thing.)

(I only checked the screen-v4 branch so far, but I assume that the
master branch shows the same issue.)

So please reapply commit d340b02c, e.g. by cherry-picking it, against
configure.ac to stop linking against libelf again, probably in both,
the screen-v4 and the master branch. Will cherry-pick that commit for
the Debian package of screen at least.

Thanks in advance!

P.S.: I would have reported that one via Savannah, but I can't
currently reach savannah.gnu.org nor can I reach git.sv.gnu.org to
check if that has been fixed recently.

                Regards, Axel
