Over the weekend, I ran an experimental amd64 bulk build at home with lld as ld(1). That produced a surprising number and variety of failures, see the list below. I don't know if these can all be blamed on the respective port or if there are problems in lld as well.
Many of "undefined symbol" errors are straightforward: The program refers to a symbol from some libfoo, but fails to explicitly link with this library. This should be fixed. I'm not sure about the _Unwind* ones, which refer to libc++abi. The other errors are largely mysterious to me. audio/audacity undefined symbol: g_signal_connect_data benchmarks/wrk string table non-null terminated databases/pgmodeler undefined symbol: backtrace devel/arm-none-eabi/gcc-linaro cannot preempt symbol: __stack_smash_handler devel/avr/gdb duplicate symbol: _initialize_gdbarch_utils devel/ffcall can't create dynamic relocation R_X86_64_64 against local symbol in readonly segment devel/xtensa-elf/gcc cannot preempt symbol: __stack_smash_handler editors/emacs cannot preempt symbol: memcpy editors/emacs21 cannot preempt symbol: __stack_smash_handler editors/xemacs21/stable cannot preempt symbol: __stack_smash_handler emulators/higan undefined symbol: _Unwind_Resume emulators/mednafen cannot preempt symbol: __stack_smash_handler emulators/retroarch undefined symbol: libusb_init games/gargoyle undefined symbol: gtk_init games/nethack/3.6,qt undefined symbol: _Unwind_Resume games/redeclipse undefined symbol: XOpenDisplay games/tome4 undefined symbol: _Unwind_GetCFA games/uqm undefined symbol: atan2 games/warzone2100 undefined symbol: ogg_sync_init games/xteddy undefined symbol: XShapeCombineMask games/zaz undefined symbol: vorbis_info_init lang/fpc invalid alignment of section headers lang/gcc/4.9 configure: Link tests are not allowed after GCC_NO_EXECUTABLES lang/ghc configure: C compiler cannot create executables lang/myrddin section sh_addralign is not a power of 2 lang/nim unable to find library -lm lang/pypy cc: linker command failed due to signal misc/magicpoint configure: C compiler cannot create executables misc/rocrail undefined symbol: operator new(unsigned long) net/hexchat unable to find library -lc net/openvpn-auth-ldap configure: Could not locate a working Objective-C runtime net/telepathy/folks edbus-private not found net/transmission undefined symbol: libintl_gettext net/utox target emulation unknown news/pan undefined symbol: libiconv_close productivity/glabels edbus-private not found security/opensc unable to find library -lpthread security/xca undefined symbol: _Unwind_Resume sysutils/firmware/vmm ld -nopie -znorelro does not properly handle alignments sysutils/memtest86+ unknown argument: --warn-constructors www/lighttpd unable to find library -lc www/mono-xsp configure: C compiler cannot create executables www/mozplugger target emulation unknown x11/gnome/code-assistance configure: C compiler cannot create executables x11/gnustep/terminal undefined symbol: libiconv x11/rox-filer undefined symbol: floor -- Christian "naddy" Weisgerber na...@mips.inka.de
