| | | | | | | | and nxcompshad libraries. No change to the actually installed relinked nxagent(-relink) binary that gets installed - only affects the temporary executable build binary.

| | | | | | I am not sure about the maximum font name length in X but just in case use snprintf instead of memcpy to be sure nothing dangerous can happen here.

| | | | | | | This is a partial copy from XlibInt.c's _XPrintDefaultError, which had some minor changes since being copied. Update to reflect these changes. Also comment some more lines as their result was unused an cluttered the output.

* nx-X11: reintroduce creation of libX11 compat symlinks.Mihai Moldovan2017-12-302-0/+25

* nxagent: implement RPATH/RUNPATH override for libX11.Mihai Moldovan2017-12-303-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* zlib compatibility: whenever we want -I flags only, assume that the headers ↵Mihai Moldovan2017-12-162-3/+3

| | | | | | | | Partly reverts ec30a857eb0d67b232f8d43e63a6370023f4c4d0, but in a forward-compatible manner. Legacy libXfont1 versions are automatically detected by the main Makefile.
