[odb-users] Re: when running odb compiler get error "#error libodb-mysql header... THANKS, unfortunately now "internal compiler error: Bus error"

Hi Boris,

Thanks so much for the tip "#ifndef ODB_COMPILER".  I was going down that
route but didn't know if I was a better way.

Now it "compiles" without error but it does not generate any real code,
just stub code with no data members (aka fields).  I turned on --trace and
the compile end with the following:
*** WARNING *** there are active plugins, do not report this as a bug
unless you can reproduce it without enabling any plugins.

                 from MyClass2.h:10:
../Release/include/pplx/pplxtasks.h: In function ‘void
pplx::details::_ScheduleFuncWithAutoInline(const std::function<void()>&,
pplx::details::_TaskInliningMode_t)’:

error
     static void _ScheduleFuncWithAutoInline(const std::function<void ()> &
_Func, _TaskInliningMode_t _InliningMode)

I am compiling with c++11, because the default(c++98) throws all kinds of
compile errors on some of the packages (cpprest & pplx) that my code uses.

Attached is the complete trace, but I expect to help me you would need the
source for UsingClass, but before I go through the effort of trimming it
down to the relevant code I thought I would ask you have any advice to get
this to work on myClass2?
