yes. There is an incompatibility between gcc 4.8, some Linux kernels and
compiling Linux with g++ instead of gcc.

The solution is to
1) either switch to gcc 4.9+ or
2) add

   VBOX_WITH_VBOXDRV=
   VBOX_WITH_ADDITION_DRIVERS=
   
   to your LocalConfig.kmk. Compiling the R0 drivers is not necessary
   during the normal build process on Linux. You know, these drivers need
   to be compiled separately against the running kernel anyway.

Kind regards,

Frank
