It must be something in the environment. 55965 5 eduard.bartosh 2015-10-29 09:35:38 +0000 unset LDFLAGS before running configure made it working. I'll dig further. 55971 6 eduard.bartosh 2015-10-29 10:30:03 +0000 The reason is this part of LDFLAGS: -Wl,-rpath-link,/home/ed/yocto/poky/build/tmp/sysroots/i686-linux/lib Because of above rpath option linker takes yocto dbus libraries instead of host ones and breaks as some symbols required by pulseaudio are not provided by yocto dbus. 55990 7 eduard.bartosh 2015-10-29 13:22:30 +0000 Both qemu and qemu-native builds worked for me on Ubuntu 15.10 and OpenSUSE 12.3 with this patch: https://gist.github.com/bartosh/b589e457a9fe60640fe1 The patch just clears up LDFLAGS and CFLAGS, making the build to use only host libraries. Mixing yocto native libraries with host libraries can and will cause similar build issues from my point of view. Thoughts? 56029 8 richard.purdie 2015-10-30 07:09:13 +0000 (In reply to comment #7) > Both qemu and qemu-native builds worked for me on Ubuntu 15.10 and OpenSUSE > 12.3 with this patch: https://gist.github.com/bartosh/b589e457a9fe60640fe1 > > The patch just clears up LDFLAGS and CFLAGS, making the build to use only > host libraries.

If you look at the qemu recipe, there are a number of DEPENDS which it expects to find built by the OE build process. I tried your patch and saw: | ERROR: User requested feature uuid | configure was not able to find it. | Install libuuid devel for example (since the util-linux-native dependency is now masked out. We'd also have similar issues if the host didn't have glib-2.0-devel, zlib-devel and so on. Its therefore not this simple unfortunately, you just have a lot of -devel packages installed on the machine you tested on. 56030 9 richard.purdie 2015-10-30 07:09:36 +0000 I suspect upgrading dbus to the newer version will "fix" this btw. 56036 10 eduard.bartosh 2015-10-30 09:25:00 +0000 I agree that upgrading dbus might fix this issue for Ubuntu. However it might break it for other distro(s). My point was that we should choose one way(link qemu with yocto libs) or another(link with system libs) instead of balancing on the edge as we do now. I can try to upgrade dbus, but it can potentially break qemu build on other distros. Are you sure we want that now? 56066 11 eduard.bartosh 2015-10-31 22:22:00 +0000 Upgraded dbus: http://lists.openembedded.org/pipermail/openembedded-core/2015-October/112168.html Tested on Ubuntu 15.10 and OpenSUSE 13.2 by building core-image-minimal and running it with runqemu script. It worked just fine. Tried an idea of running configure several times until it succeeds: - first time without any additional options - second time with adding output of pkg-config --libs sdl to LDFLAGS - third time with adding output of pkg-config --libs dbus-1 to LDFLAGS Does this make sense for you? 56074 12 eduard.bartosh 2015-11-02 08:57:14 +0000 dbus upgrade has been rejected: http://lists.openembedded.org/pipermail/openembedded-core/2015-November/112173.html Any other ideas how to fix it? Does it make sense to try running configure several times? 56135 13 eduard.bartosh 2015-11-03 13:02:07 +0000 Moved to 2.1 as upgrading dbus just before a release is too dangerous. 56169 14 eduard.bartosh 2015-11-04 08:31:10 +0000 Sent workaround for review: http://lists.openembedded.org/pipermail/openembedded-core/2015-November/112207.html 56702 15 alex.kanavin 2015-11-23 16:11:51 +0000 This happens on Debian testing/stretch/sid as well, for the same reason. 56725 16 eduard.bartosh 2015-11-24 09:27:44 +0000 Do you want me to update a workaround to work for Debian? 56730 17 eduard.bartosh 2015-11-24 10:22:49 +0000 Robert, Chen: Any plans for dbus upgrade? My attempt to upgrade to 1.10 was rejected http://lists.openembedded.org/pipermail/openembedded-core/2015-November/112173.html as I tried to do it just before a release. I'm just wondering if you can help with this? 56731 18 ross.burton 2015-11-24 10:32:31 +0000 Can you rework the workaround to remove the distro check and just do it all the time, and submit it to the list? 56732 19 ricardo.ribalda 2015-11-24 10:34:05 +0000 Probably a stupid question, but why dont we want to compile a host version of libsdl? if I got it right, it is the root of the problem. 56733 20 ross.burton 2015-11-24 10:39:40 +0000 Because that means building pulseaudio-native mesa-native gtk-native and more. 56736 21 eduard.bartosh 2015-11-24 11:09:41 +0000 Sent updated patch: http://lists.openembedded.org/pipermail/openembedded-core/2015-November/113264.html please review 56819 22 ross.burton 2015-11-26 17:26:20 +0000 Ed's patch appears to break on older systems with our friend the libx11/libext _XEatDataWords error. Testing my patch on the autobuilder now. 56996 23 eduard.bartosh 2015-12-03 14:59:05 +0000 How it went with your patch? Did it work? 57071 24 ross.burton 2015-12-07 12:25:07 +0000 After spending too long looking at this I decided we should build a libsdl-native after all. I've a patch which adds libsdl-native support with a minimal PACKAGECONFIG so it doesn't massively pull in build dependencies. 57137 25 francisco.j.pedraza.gonzalez 2015-12-08 23:19:44 +0000 Thanks a lot for the help :) 57268 26 dl9pf 2015-12-15 10:43:32 +0000 (In reply to comment #24) > After spending too long looking at this I decided we should build a > libsdl-native after all. > > I've a patch which adds libsdl-native support with a minimal PACKAGECONFIG > so it doesn't massively pull in build dependencies. Can we do a backport to 2.0 for this then as it breaks with current distros like 15.10 ? I agree on the "either native or target" linking - just no mix. 58237 27 ross.burton 2016-01-26 14:26:00 +0000 Poky switched over to building libsdl-native in 685daeb6e265ddbd28be0ef44dcc356727b99375. oe-core was fixed in 3d6c31c3a4ff34376e17005a981bb55fc6f7a38f. 58882 28 stanciux.mihail 2016-02-11 13:48:58 +0000 Verified for 2.1_M2: 3d2c0f5902cacf9d8544bf263b51ef0dd1a7218c 58997 29 stanciux.mihail 2016-02-15 09:07:02 +0000 Still present in 2.0.1_rc6: 5b12268f6e17574999f91628a60e21711cf62ee4 59617 30 alexandru.c.georgescu 2016-03-02 08:31:01 +0000 (In reply to comment #29) > Still present in 2.0.1_rc6: 5b12268f6e17574999f91628a60e21711cf62ee4 present in 2.0.1.rc7 as well 59810 31 tracy.graydon 2016-03-08 22:00:30 +0000 Incidentally, I just ran into this same issue with Debian 8 last night. I installed libsdl-dev to fix it, but I will try to reproduce it and add the particulars. Essentially the same error message as above. 59814 32 ross.burton 2016-03-08 22:44:42 +0000 If installing libsdl-dev works then that isn't the problem. The problem is that on some distributions after installing libsdl-dev it still won't build. 61535 33 a.schuller 2016-04-21 20:13:54 +0000 I have remove the whitespace in build/conf/local.conf from the rows PACKAGECONFIG_append_pn-qemu-native = "<here>sdl" PACKAGECONFIG_append_pn-nativesdk-qemu = "<here>sdl" and add the line below to my local.conf file BUILD_LDFLAGS_prepend_pn-qemu-native = "-Wl,-rpath-link,/lib/x86_64-linux-gnu" now it works well. here my currently local.conf MACHINE ??= 'cgtimx6' DISTRO ?= 'poky' PACKAGE_CLASSES ?= "package_rpm" EXTRA_IMAGE_FEATURES = "debug-tweaks" USER_CLASSES ?= "buildstats image-mklibs" PATCHRESOLVE = "noop" BB_DISKMON_DIRS = "\ STOPTASKS,${TMPDIR},1G,100K \ STOPTASKS,${DL_DIR},1G,100K \ STOPTASKS,${SSTATE_DIR},1G,100K \ STOPTASKS,/tmp,100M,100K \ ABORT,${TMPDIR},100M,1K \ ABORT,${DL_DIR},100M,1K \ ABORT,${SSTATE_DIR},100M,1K \ ABORT,/tmp,10M,1K" PACKAGECONFIG_append_pn-qemu-native = "sdl" PACKAGECONFIG_append_pn-nativesdk-qemu = "sdl" ASSUME_PROVIDED += "libsdl-native" CONF_VERSION = "1" DL_DIR ?= "${BSPDIR}/downloads/" ACCEPT_FSL_EULA = "1" BUILD_LDFLAGS_prepend_pn-qemu-native = "-Wl,-rpath-link,/lib/x86_64-linux-gnu" regards, alex 61538 34 ross.burton 2016-04-21 21:34:28 +0000 That whitespace is actually important. If you want to disable sdl the comment out those lines. There's a series of patches to fix this properly in the jethro branch, which should be released as 2.0.2 shortly. 61539 35 a.schuller 2016-04-21 22:08:58 +0000 I don't understand, why is the whitespaces important actually? Please explain this, to get more comprehension. I just beginning to work with yocto. 61541 36 francisco.j.pedraza.gonzalez 2016-04-22 01:02:09 +0000 (In reply to comment #35) > I don't understand, why is the whitespaces important actually? > Please explain this, to get more comprehension. > I just beginning to work with yocto. Hi In the latest versions of ubuntu this fix is not neede anymore. Are you facing it? 61546 37 ross.burton 2016-04-22 07:57:38 +0000 _append doesn't insert whitespace so if the value is a whitespace separated list then you need to add your own whitespace. If you are disabling SDL (which is likely what your packageconfig changes were doing) then you don't need any further changes to the qemu build, the linker flag changes were an attempt to make the build work when SDL is enabled. Repeating that this is fixed in master and jethro branches, and will be released in 2.0.2 shortly. 61552 38 stanciux.mihail 2016-04-22 10:03:18 +0000 Marking as verified.
