Description royalsheeplauncher 2015-06-19 05:18:49 UTC

On a hardened gentoo install as virtualbox guest, x11-drivers/xf86-video-virtualbox-4.3.28 compiles and installs, but a reboot results in xorg failure to load vboxvideo and fallback to vesa driver.

Xorg.0.log:
vboxvideo_drv.so: undefined symbol: vgaHWFreeHWRec

It is the same bug reported here:
https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1280292

On my system I was able to fix this by doing:

gcc-config x86_64-pc-linux-gnu-4.8.4-vanilla
source /etc/profile
emerge --oneshot x11-drivers/xf86-video-virtualbox
#(gcc-config x86_64-pc-linux-gnu-4.8.4)

For some reason could not get the per-package package.env LDFLAGS "-z,lazy" flag appending to work, but better you fix on package anyway. (maybe something else that should be fixed in upstream package instead, but damned if I know)

RE: the "-z,lazy" flag, I mean I could not get the flag recognized by the compiler (vbox driver still contained BINDNOW section). So I don't know for sure if changing that flag alone would fix it or not, but vanilla profile surely contains the fix.
