Created attachment 437452 [details] build log I am building libunwind-1.1 on a CoreOS machine (based on gentoo and uses the same ebuilds) and getting the following error: /bin/sh ../libtool --tag=CC --mode=link x86_64-cros-linux-gnu-gcc -O2 -pipe -mtune=generic -g -fexceptions -Wall -Wsign-compare -Wl,-O1 -Wl,--as-needed -o test-coredump-unwind test-coredump-unwind.o ../src/libunwind-coredump.la ../src/libunwind-x86_64.la libtool: link: x86_64-cros-linux-gnu-gcc -O2 -pipe -mtune=generic -g -fexceptions -Wall -Wsign-compare -Wl,-O1 -o .libs/test-coredump-unwind test-coredump-unwind.o -Wl,--as-needed ../src/.libs/libunwind-coredump.so ../src/.libs/libunwind-x86_64.so /usr/libexec/gcc/x86_64-cros-linux-gnu/ld: warning: libunwind.so.8, needed by ../src/.libs/libunwind-x86_64.so, not found (try using -rpath or -rpath-link) ../src/.libs/libunwind-x86_64.so: undefined reference to `_Ux86_64_setcontext' collect2: error: ld returned 1 exit status Makefile:794: recipe for target 'test-coredump-unwind' failed make[1]: *** [test-coredump-unwind] Error 1 If I emerge libunwind-1.0.1 it seems to work, but not libunwind-1.1.

this is fixed in 1.1-r1 already
(In reply to SpanKY from comment #2) > this is fixed in 1.1-r1 already sys-libs/libunwind-1.2_rc1 still fails. Shall I open a new bug?
(In reply to Matt Whitlock from comment #3) i've pushed a commit already for 1.2_rc1 to pull the change from 1.1-r1 the test failures are still covered in bug 461958
(In reply to SpanKY from comment #4) > i've pushed a commit already for 1.2_rc1 to pull the change from 1.1-r1 When should I expect to be able to rsync your fix? I've just sync'd a few minutes ago, and I'm still getting the same failure in 1.1, 1.1-r1, and 1.2_rc1. /usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: ./.libs/libunwind-dwarf-local.a(Lstep.o): multiple definition of '_ULx86_64_step' /usr/lib/gcc/x86_64-pc-linux-gnu/5.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: x86_64/.libs/Lstep.o: previous definition here collect2: error: ld returned 1 exit status This same failure occurs even if I force usage of the BFD linker (instead of Gold), although the error message is phrased a little differently: ./.libs/libunwind-dwarf-local.a(Lstep.o): In function `_ULx86_64_step': /var/tmp/portage/sys-libs/libunwind-1.2_rc1/work/libunwind-1.2-rc1/src/x86_64/Gstep.c:57: multiple definition of `_ULx86_64_step' x86_64/.libs/Lstep.o:/var/tmp/portage/sys-libs/libunwind-1.2_rc1/work/libunwind-1.2-rc1/src/x86_64/Gstep.c:57: first defined here collect2: error: ld returned 1 exit status
(In reply to Matt Whitlock from comment #5) then it's not the same error as any reported thus far, so you should open a new bug report
(In reply to SpanKY from comment #6) > you should open a new bug report https://bugs.gentoo.org/show_bug.cgi?id=586208
FWIW, I can verify that 1.1-r1 fixed the problem I was seeing. Thank you!
