you should NOT need IN_RING0, this can only cause problems.
VBOX_WITH_XPCOM should be automatically detected based on RT_OS_...
You missed VBOX_WITH_XPCOM_NAMESPACE_CLEANUP, too.
Also I wonder why you do it this way, normally these defines are
specified in the compiler command line, see below.

These are compile time assertions which fail... I guess it's the first
two AssertCompile ones which check the size of the Utf16 char type to be
consistent. It means you forgot to make sure that you're compiling the
code with -fshort-wchar. Again see the sample makefile, it contains all
In other words, make sure that you compile with
g++ -fshort-wchar -DRT_OS_LINUX -DVBOX_WITH_XPCOM_NAMESPACE_CLEANUP
plus whatever options you need for the rest of your code.
