synclient.o: relocation R_X86_64_32 against 'a local symbol' can not be used when making a shared object; recompile with -fPIC but -fPIC is already listed in the flags in the Makefile: CDEBUGFLAGS = -fPIC ... CFLAGS = $(CDEBUGFLAGS) and other stuff from ebuilds (nothing modified) Reproducible: Always Steps to Reproduce: 1. emerge synaptics 2. 3. please forgive me for put the bug in "Major" category. IMHO the "-fPIC" issue it's something we should solve not just for this package but for the compiler gcc-3.4.4 or the distro layout: it's too often on the forum and bugzilla for amd64 and often not fixable by changing the CFLAGS in Makefile.

please look at the bug #93862: the solution it's the same :) you can also find an explanation there. Thanks to tips from other users I solved by: adding -fPIC to CFLAGS adding -hardened to USE flags *both* necessary (I first tried with the only -hardened and it fails) and both, temporarely added to /etc/make.conf (no command line) emerge gcc (updated to 3.4.4-r1) emerge synaptics synaptics compiled and works fine! the same for mplayer, bug #93862: ok now! thanks
adding -fPIC to CFLAGS is not an acceptable solution and will cause breakage with other packages, so this is far from solved
works fine here too, however, in comment 5 there is: x86_64-pc-linux-gnu-gcc -c -march=athlon64 -O2 -pipe -fomit-frame-pointer -pedantic -Wall -Wpointer-arith -fno-merge-constants -fno-pic -I. hardened people: Do you set that flag?
Short answer - no, Long answer - we never set -fPIC, but we do set -fPIE unless one or more of static, shared, ostdlib, nostartfiles, -fno-PIC, -fno-pic, -fPIC, -fpic, -fno-PIE, -fno-pie, -nopie are set, or we're building the kernel. Here, the -fno-pic stops it setting -fPIE. In general hardened want -fPIC for libraries, -fPIE for applications. PIE is similar to PIC. Note that you won't see what the hardened compiler gets up to in make logs - the flag twiddling is behind-the-scenes specs file stuff. An easy way to check whether the hardened compiler makes a difference is to switch between -hardened (Default on hardened systems) and -vanilla (default on non-hardened systems) using gcc-config and try it both ways - no need to waste time re-building gcc. From comment #6 it looks like the problem persists when using a vanilla compiler, unless -fPIC is appended. disperato: just to re-affirm, because it's important - adding "-fPIC" to CFLAGS will break things big-time, so take that out of CFLAGS before you emerge anything else :)
Created attachment 67952 [details] Build shared library for X's dlloader, properly PIC I had a further look at this today, and created the attached revised ebuild for consideration. The main reason for modifying the ebuild is to eliminate "text relocations" (i.e. non-PIC code) from the shared library built for the dlloader in Xorg. Shared libraries should be PIC (whether a system is "hardened" or not), and when building modules for X to be loaded via the dlloader, the modules are shared libraries. However the upstream build only makes the old elf-loader style modules, which are simply partially-linked collections of objects and which are not PIC. The attached ebuild extends the existing dlloader support with improved integration with the existing makefile. This eliminates the need for overriding src_compile and simplifies src_install, which is nice. I've explained the modifications the ebuild makes to the Makefile in the ebuild itself. As far as the elf-loader is concerned, the ebuild should generate the same object collection as it did previously.
This bug appears to be fixed. Can it be closed?
Solution provided so hardened team have done their bit. Over to package maintainer to patch or push upstream as they see fit. (btw textrel issue is not amd64-specific; same on x86)
I've added a Makefile patch in 0.14.4 (added to cvs 6 minutes ago or so) that I'll be pushing upstream to the synaptics maintainers. Closing bug.
Adding '-fno-pic' unconditionally to the client compilation flags causes textrels in the client apps when built with the hardened compiler.
0.14.4-r1 has no more -fno-pic as you (kevin) and I discussed with upstream
