[odb-users] -mtune=/dev/null

[Don Burns]

Hello,

I've just been introduced to odb and have run into a problem that may have
been covered before, but I was unable to come up with anything searching
the archives.  This is my first stab at the hello world program:

$ *odb -d mysql --generate-query person.hxx*
cc1plus: error: bad value (‘/dev/null’) for ‘-mtune=’ switch

My platform:

   - Ubuntu 18.04
   - odb: 2.4.0
   - g++: 7.5.0

Running the above command with -v:
$ *odb -v -d mysql --generate-query person.hxx*

I don't see any -mtune=/dev/null in the generated cc1plus outputs.  Any
help would be appreciated.

Thanks,
