[X2Go-Commits] [nx-libs] 18/45: NXAGENT_UPGRADE code cleanup:

This is an automated email from the git hooks/post-receive script. x2go pushed a commit to branch 3.6.x in repository nx-libs. commit a5f71f084e9f32e947a04da69edb7aae96d61697 Author: Mike Gabriel <mike.gabriel@das-netzwerkteam.de> Date: Tue Apr 14 09:42:35 2015 +0200 NXAGENT_UPGRADE code cleanup: NX agent contains/ed two build trees. An old one (probably pre-3.x.y) and a "newer" one. The "newer" code tree used to become enabled by setting NXUpgradeAgentServer in nx-X11/config/cf/host.def to YES. As building the NXUpgradeAgentServer has been the default for years now, we drop all code that does not get used at build time for NXUpgradeAgentServer == YES (i.e., the code that belongs to the pre-3.x.y phase of NX agent). --- nx-X11/config/cf/host.def | 7 -
