This is an automated email from the git hooks/post-receive script. x2go pushed a commit to branch 3.6.x-rpm-debug in repository nx-libs. commit 26ab7b8a79e6c901518d9136d00b79e2905dab58 Author: Mihai Moldovan <ionic@ionic.de> Date: Tue Dec 26 04:06:40 2017 +0100 nxagent: implement RPATH/RUNPATH override for libX11. As discussed in ArcticaProject/nx-libs#610, we need a way to load libNX_X11 as a fake version of libX11 into nxagent's address space. For doing so, we have to link against libX11 at build-time and specify a(n) RPATH/RUNPATH to our libX11 -> libNX_X11 compat symlinks. This commit is essentially doing a cross between options 3 and 4 discussed in the provided GH issue. We link libX11 early (before specifying -Lcompat_symlinks_dir), so that the linker finds the "real" libX11 version with the libX11 SONAME. This leads to our binary depending upon both libX11 and libNX_X11 SONAMEs. We already always added RPATH/RUNPATH, but these values are not passed down to dependent libraries. What happens at run-time is that the loader searches for a libX11 SONAME, takes RPATH/RUNPATH into account and loads our libNX_X11 library instead via the compat symlinks. This satisfies the libX11 SONAME and dependent libraries will *not* load the system libX11 version again. Debian's dpkg-shlibdeps isn't quite happy about this mismatching SONAME situation, so instruct to look the other way while we're minding our business.
