* Makefiles: drop support for NXwinUlrich Sibiller2020-05-071-147/+1
| | | | | | | | We have never built nxwin within this tree. And we never shipped it. So drop the according logic. We have also removed CYGWIN stuff in the past so nxwin probably would not compile/work anyway...
* nxagent: drop NXextension.cUlrich Sibiller2019-11-021-3/+0
| | | | | instead of including it and creating NXextension.o we can simply use the dix version. There are no NX specials anymore.

* nxagent/Imakefile: remove ../../exports/libUlrich Sibiller2019-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nxagent links system libraries that link against libX11. Unfortunately, nxagent (and libXcompshad) require a modified libX11 version, nicknamed libNX_X11, for proper functioning. Fortunately, this one can act as a drop-in replacement for the system libX11. So we’ll hack our way out: add a DT_NEEDED entry for libX11 by linking against the system library when building nxagent and link the other system libraries later and set DT_RUNPATH to a special directory containing symlinks from libNX_X11 to libX11. This tricks the loader into pulling in the "fake" libX11 version without checking its SONAME and thus satisfying the DT_NEEDED entry early on - specifically also for the system libraries. Ex.: readelf -a /usr/bin/nxagent | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [libX11.so.6] ... 0x0000000000000001 (NEEDED) Shared library: [libNX_X11.so.6] ... If, however, you run the build a second time, it will find the newly created libX11 links in ../../exports/lib (used as an additional library search path) instead of the system libX11. The results in a binary looking like this: 0x0000000000000001 (NEEDED) Shared library: [libNX_X11.so.6] ... With such a setup, the whole magic falls apart and system libraries will suddenly pull in the actual system libX11 file. We initially believed a compiler call such as: ${CC} [--unrelated-options ...] [-Lunrelated_library_path ...] -lX11 [more options like -l and -L] -L../../exports/lib -lother_libraries to do "the right thing" and link against the system libX11 (or, at worst, a libX11 found in the library directory search list preceding the link call) and use ../../exports/lib only for later linking operations, since the order of options matters. However, this turned out to be blatantly wrong: while the order of -L arguments does matter for building the search path, the whole search path including elements from *ALL* -L arguments (and the system paths) will always be used when linking libraries. Hence, (counter-intuitively to us) both these calls will be equivalent: ${CC} [--unrelated-options ...] -la -Loverride_liba -lb [-Lunrelated_library_path ...] -lc ${CC} [--unrelated-options ...] -Loverride_liba [-Lunrelated_library_path ...] -la -lb -lc By removing LDPRELIBS from NXAGENTSYSLIBS, ../../exports/lib is no longer used during building/linking and the binaries are built reproducibly. We never intended to use this directory at link time anyway.

| | | | | | | | | | for nxagent regeneration. Updating timestamps on object files and libraries used to compose nxagent is only meaningful for actual files within the buildroot. External dependencies would be ignored anyway, and worse, cause older GNU Make versions to fail if they contain special characters like a percent sign, which is typically interpreted as a wild card character.

* nxagent: implement RPATH/RUNPATH override for libX11.Mihai Moldovan2017-12-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | Content of that file is now hard-coded. Adopting an exact copy of os/oscolor.c from X.org leads to this compiler warning: ``` oscolor.c:844:1: warning: string length ‘7614’ is greater than the length ‘4095’ ISO C99 compilers are required to support [-Woverlength-strings] }; ^ ``` This will be address later in coordination with X.org. Note: there is a tiny change in oscolor.c as we ship it. The original X.org file includes <X11/keysym.h> which seems unneeded. We drop that one line from oscolor.c. Fixes ArcticaProject/nx-libs#259.
