[odb-users] C++11 with clang on OSX 10.8

[Jeff Waller]

Just as a base of comparison, I have no problems building and linking
on OS X 10.7 using clang.

However some differences

1) I do not use the packaged odb, but rather generate the source on linux
and simply include the generated source as part of the distribution.  I
don't think this makes any difference, but it's worth mentioning.

2) Version is 2.2.2

3) libodb, libodb-sqllite, libodb-boost are built from source:
./configure CC=clang CXX=clang++, but no other flags.

And then of course own project is built once again
./configure CC=clang CXX=clang++ and no other flags

4) and from above, using autotools not cmake

Maybe as a test, we could compare link, compile steps?
