Compiling Virtualbox with VBOX-KVM Errors and Fixes

I wanted to post my notes on this for anyone else trying to compile Virtualbox with virtualbox-kvm from source on a modern Linux OS.

The Error: I was getting a unit32_t error and never could figure out what it was when I started the compile.

The Fix: was to give it a revision on the kmk command

# kmk VBOX_SVN_REV=165881

The Error: Source was unable to find the Qt6 StateMachine module. This also triggered a larger issue of two installs of Qt6 –the system one on LinuxMint at /usr/bin/Qt, but that issue is later down the post…

The Fix: use the maintenance tool for the install. It seems to have been installed on the system side, but whatevs.

 # /opt/Qt/MaintenanceTool --am install qt.qt6.6101.addons.qtscxml

The Error: undefined symbol __memset_check error on compile

kBuild: Compiling webtest - /opt/virtualbox/VirtualBox-7.2.6/out/linux.amd64/release/obj/webservice/soapClient.cpp kmk: *** Exiting with status 2 kBuild: Checking for unresolved symbols in /opt/virtualbox/VirtualBox-7.2.6/out/linux.amd64/release/bin/additions/vboxvideo_drv_70.so /opt/virtualbox/VirtualBox-7.2.6/src/bldprogs/checkUndefined.sh: following symbols not defined in the files /opt/virtualbox/VirtualBox-7.2.6/src/VBox/Additions/x11/vboxvideo/../undefined_xfree86 /opt/virtualbox/VirtualBox-7.2.6/src/VBox/Additions/x11/vboxvideo/../undefined_xfree86_modules /opt/virtualbox/VirtualBox-7.2.6/src/VBox/Additions/x11/vboxvideo/../undefined_xorg: __memset_chk kmk: *** [/opt/virtualbox/VirtualBox-7.2.6/src/VBox/Additions/x11/vboxvideo/Makefile.kmk:459: /opt/virtualbox/VirtualBox-7.2.6/out/l

The Fix: added __memset_check to shared undefined_xorg whitelist

echo "__memset_chk" >> /opt/virtualbox/VirtualBox-7.2.6/src/VBox/Additions/x11/undefined_xorg

The Error: KVM test linking failure around tstVMMUnitTests-1 in the testcase Makefile.kmk

/path/to/VirtualBox-7.2.6/src/VBox/VMM/testcase/Makefile.kmk

The Fix: Comment out tstVMMUnitTests-1

The Error: Issues on not finding the Qt6 Help module. Was getting various errors on this during compiles.

The Fix: Use MaintenanceTool to install the Qt6 Help — could have also been related to my two Qt6 installs.

/opt/Qt/MaintenanceTool --am install qt.qt6.6101.addons.qthelp

The Error: I had dual Qt6 installs. The system one at /usr/bin/Qt and the one I wanted to really use at /opt/Qt – so it kept conflicting.

The Fix: Purge/remove all system stuff. and inform the config globally to point at /opt/Qt

# echo "/opt/Qt/6.10.1/gcc_64/lib" | sudo tee /etc/ld.so.conf.d/qt6.conf
# ldconfig 

Hope this page is found if/when someone else is crazy enough to try and do this.
