From ef9d66230f9697caaa77dbfc275650412d0d9c0d Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/1] Singular/Makefile.am: drop -static linker flags.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are a few hard-coded "-static" flags in the Makefile.am for
Singular that are causing weird problems for shared builds. The
visible symptom on Gentoo was a few insecure rpaths being stripped
from the "Singular" executable, but François Bissey was able to track
down the root cause, namely the "-static" that is causing libtool to
act weird.
In retrospect, this problem was also reported on Stack Overflow at,
https://stackoverflow.com/questions/17905121
The Gentoo bug is,
https://bugs.gentoo.org/712004
If we experience no problems with this patch, it will be sent upstream.
