It was reported multiple times in the status report on oe-core ML, here are latest logs: http://errors.yoctoproject.org/Errors/Details/69790/ http://errors.yoctoproject.org/Errors/Details/69831/ 63493 1 jku 2016-06-30 10:43:46 +0000 It seems libxcb pkg-config now has stricter Requires rules and piglit has been abusing the over-linking that resulted from the more lax rules. Will fix in my upcoming piglit upgrade branch. 63648 2 3269 jku 2016-07-05 08:20:37 +0000 Created attachment 3269 cmake: Link utils with xcb explicitly I just can't reproduce this, which is weird because there's no autodetection tomfoolery that I can see. I've tried building a "qemux86 nodistro piglit" and it builds, whatever I do. Looking at the linker flags it does seem like a missing "-lxcb", but it's weird that a) it links fine here (somewhat surprisingly) b) even in the failure logs gcc links fine, only g++ fails Martin, feel free to test the patch if you have an easy way to do that. Otherwise I guess I'll send this patch and we'll see if it helps in your next build. 64396 3 Martin.Jansa 2016-07-24 12:07:39 +0000 Not the error got different: | Scanning dependencies of target fbo-drawbuffers-arbfp | /home/jenkins/oe/world/shr-core/tmp-glibc/sysroots/x86_64-linux/usr/bin/arm-oe-linux-gnueabi/arm-oe-linux-gnueabi-gcc -march=armv5te -mthumb --sysroot=/home/jenkins/oe/world/shr-core/tmp-glibc/sysroots/qemuarm -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/home/jenkins/oe/world/shr-core/tmp-glibc/work/armv5te-oe-linux-gnueabi/piglit/1.0+gitrAUTOINC+c39e41a865-r0=/usr/src/debug/piglit/1.0+gitrAUTOINC+c39e41a865-r0 -fdebug-prefix-map=/home/jenkins/oe/world/shr-core/tmp-glibc/sysroots/x86_64-linux= -fdebug-prefix-map=/home/jenkins/oe/world/shr-core/tmp-glibc/sysroots/qemuarm= -Wall -std=gnu99 -Werror=vla -Werror=pointer-arith -Werror=variadic-macros -g -march=armv5te -mthumb --sysroot=/home/jenkins/oe/world/shr-core/tmp-glibc/sysroots/qemuarm -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed CMakeFiles/fbo-fragcoord.dir/fbo-fragcoord.c.o -o ../../../../bin/fbo-fragcoord -rdynamic ../../../../lib/libpiglitutil_gl.so.0 -lGL ../../../../lib/libpiglitutil.so.0 -lrt -lpng -lz -lm -lEGL -lwaffle-1 -lX11 -lGL -Wl,-rpath,/home/jenkins/oe/world/shr-core/tmp-glibc/work/armv5te-oe-linux-gnueabi/piglit/1.0+gitrAUTOINC+c39e41a865-r0/build/lib: | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlsym' | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlerror' | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlopen' | collect2: error: ld returned 1 exit status | make[2]: Leaving directory `/home/jenkins/oe/world/shr-core/tmp-glibc/work/armv5te-oe-linux-gnueabi/piglit/1.0+gitrAUTOINC+c39e41a865-r0/build' | make -f target_api/gl/tests/fbo/CMakeFiles/fbo-drawbuffers-arbfp.dir/build.make target_api/gl/tests/fbo/CMakeFiles/fbo-drawbuffers-arbfp.dir/build Are you using gold with nodistro?

(In reply to comment #3) > Are you using gold with nodistro? You might need to enable gold in order to > reproduce this. This sounds like a really good guess: I wasn't using gold. I'm now on holiday, back on August 12 or so. Maxin: if you want to try reproducing the build failure with ld-is-gold and then adding "-ldl" to the relevant linker flag, feel free. 64727 6 maxin.john 2016-08-01 14:42:15 +0000 > > (In reply to comment #3) > > Are you using gold with nodistro?

Recreated the build error with : DISTRO_FEATURES_append = " ld-is-gold opengl" in local.conf | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlsym' | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlerror' | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to 'dlopen' | collect2: error: ld returned 1 exit status As you have mentioned, this fixes it: LDFLAGS_append_qemux86 = " ${@bb.utils.contains('DISTRO_FEATURES', 'ld-is-gold', '-ldl', '', d)}" 65219 7 jku 2016-08-16 08:57:26 +0000 The non-optimal fix was taken into master so builds should no longer break (and so the bugs doesn't really need to be medium+ anymore). I'll keep the bug open though: LDFLAGS_append is not really the appropriate fix. I'll send a build system patch upstream soon along with the xcb link fix. 66187 8 jku 2016-09-15 06:36:02 +0000 commit 2e8c59d059b21dce23c848e837bd98de5e21dafd Author: Jussi Kukkonen <jussi.kukkonen@intel.com> Date: Tue Sep 13 11:46:40 2016 +0300 piglit: Backport linker flag patch Use the correct build system patch instead of adding linker flags in recipe. Also update upstream status for the other build patch. Fixes [YOCTO #9851].
