>From b7b414dc76b7852a77410d1812afbb79b76ca67d Mon Sep 17 00:00:00 2001 From: Akira Yokosawa <akiyks@xxxxxxxxx> Date: Wed, 27 Nov 2019 00:38:12 +0900 Subject: [PATCH 1/6] Makefile: Add compatibility check of Ghostscript and a2ping (9.50 vs 2.84p) Ghostscript 9.50 changed the default behavior regarding SAFER mode. Prior to 9.50, -dNOSAFER was assumed by default. 9.50 has made -dSAFER the default. To override this change, a2ping 2.84p now explicitly adds the option -dNOSAFER when it invokes "gs" internally. Add the compatibility check of a2ping and Ghostscript in Makefile and update FAQ-BUILD.txt accordingly.
