This is due to mesa only providing libGL is DISTRO_FEATURES 'x11' is set. However, on headless systems (think: edgerouter-lite) it doesn't make sense to build with x11 (nor libGL or mesa, but nvm), yet qemu/kvm is usefull on these systems for headless VM images (qemu --nographic ...). Possible solutions: * build qemu without SDL, x11, ... depending on DISTRO_FEATURES * make sure qemu doesn't depend on libGLU * make sure mesa actually provides libGL even on systems without x11 The first solution isn't that great because it also prevents using VNC or SPICE remotely. 54870 1 ross.burton 2015-10-01 13:08:48 +0000 "* make sure mesa actually provides libGL even on systems without x11" doesn't make any sense - libGL.so is explicitly bound to libX11 (its the GLX API). Are you sure that qemu won't do VNC/SPICE when SDL is disabled? I'm sure I've ran it headless with a VNC connection in the past. 54875 2 ross.burton 2015-10-01 13:55:13 +0000 Qemu doesn't need X11 nor SDL for VNC to work: $ runqemu qemux86 [...] VNC server running on `::1:5900' $ ldd /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/qemu-system-i386 linux-vdso.so.1 (0x00007ffef3297000) libz.so.1 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libz.so.1 (0x00007f4557f17000) libpixman-1.so.0 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libpixman-1.so.0 (0x00007f4557c6c000) libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007f4557a69000) libasound.so.2 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libasound.so.2 (0x00007f4557770000) libuuid.so.1 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libuuid.so.1 (0x00007f455756c000) libfdt.so.1 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libfdt.so.1 (0x00007f4557366000) libgthread-2.0.so.0 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libgthread-2.0.so.0 (0x00007f4557165000) libglib-2.0.so.0 => /data/poky-master/tmp/sysroots/x86_64-linux/usr/bin/../lib/libglib-2.0.so.0 (0x00007f4556e2d000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f4556c25000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f455691a000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f4556619000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f4556403000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f45561e6000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4555e3d000) /lib64/ld-linux-x86-64.so.2 (0x00007f4558d41000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f4555c39000) libSDL will only depend on GL if your distro wants OpenGL, so you should probably remove "opengl" from DISTRO_EFATURES too. Removing "sdl" from qemu's PACKAGECONFIG will stop it linking to SDL at all. 54888 3 ross.burton 2015-10-01 15:14:32 +0000 If you remove opengl and x11 from DISTRO_FEATURES then qemu will happily build without any other intervention. It links to SDL which isn't ideal but maybe you'll end up with some awesome ascii-rendered virtual machine. 54896 4 ross.burton 2015-10-01 15:25:36 +0000 In fact, this must be fixed in master already and is specific to 1.8 as I just removed x11 from DISTRO_FEATURES and qemu builds fine. Marking as a potential 1.8.1 (impact needs to be reviewed) and assigning to the 1.8 maintainer. 55191 5 dgolle 2015-10-12 15:27:47 +0000 Thanks everyone for having a deeper look at the issue! The intention is indeed to use qemu with libvirt headless with VMs providing only ASCII output, if any. I didn't verify dependencies of SPICE/VNC because we don't use them, just mentioned them because that was the only thing which came into my mind what one could potentially use SDL or libGLU for on a headless system. If that doesn't require linking against libGLU, even better. We got neither 'opengl' nor 'x11' set in DISTRO_EFATURES, however, adding both, 'x11' and 'opengl' to DISTRO_FEATURES is the current work-around leading to a successful qemu build based on poky-1.8. 57735 6 joshuagloe 2016-01-12 10:23:42 +0000 On the latest fido branch and x11 and opengl removed from DISTRO_FEATURES with the following in my local.conf: DISTRO_FEATURES_remove = "opengl x11" I am able to build qemu (tested with a qemux86 MACHINE). If this issue persists could you please provide steps for reproduction? 59469 7 ross.burton 2016-02-25 15:52:21 +0000 Closing as nobody else can replicate and the reporter hasn't provided any further feedback. Daniel, if you can still replicate this, please reopen and provide more details.
