backtrace.c uses a word size provided by libunwind. In some architectures like MIPS, libunwind makes that word size 64-bit for all variants of the architecture. In the lines #90 and #98, backtrace.c tries to do a cast to a pointer, which fails in all MIPS variants with 32-bit pointers, like MIPS32 or MIPS64 n32, because it's trying to do a cast from a 64-bit wide variable to a 32-bit pointer: Making all in os make[2]: Entering directory `/home/test/test/1/output/build/xserver_xorg-server-1.15.1/os' CC WaitFor.lo CC access.lo CC auth.lo CC backtrace.lo backtrace.c: In function 'xorg_backtrace': backtrace.c:90:20: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] if (dladdr((void *)(pip.start_ip + off), &dlinfo) && dlinfo.dli_fname && ^ backtrace.c:98:13: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] (void *)(pip.start_ip + off)); ^ cc1: some warnings being treated as errors make[2]: *** [backtrace.lo] Error 1 make[2]: *** Waiting for unfinished jobs.... Making the cast to a pointer-sized integer, and then to a pointer fixes the problem.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
