| * nxproxy/src/Makefile.am: build library using RUNPATH instead of RPATH.Mihai Moldovan2018-01-031-0/+1
| | | | | | | | | | Will only be useful at build time, since installation strips any RPATH/RUNPATH again.
| * nxproxy/configure.ac: enable libtool support.Mihai Moldovan2018-01-031-0/+3
| | | | | | | | | | | | | | | | Using libtool, the nxproxy binary will be replaced by a shell script wrapper that correctly pulls in required libraries (like libXcomp), thus making it possible to start the binary directly in the build directory. This wrapper is dropped during installation time.
| * nxproxy/configure.ac: drop --enable-cxx11.Mihai Moldovan2018-01-031-6/+0
| | | | | | | | | | | | | | | | This is a C program, so enabling or disabling C++11 support will not do anything useful. At most it'll lead to errors when using libtool, which is the next change to come...

| * nxagent: implement RPATH/RUNPATH override for libX11.Mihai Moldovan2017-12-304-2/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Fixes: ArcticaProject/nx-libs#610
