I was wondering where the symbol .test_main(int, char**) is defined if
it
comes up undefined.

I have done an object dump and I know it is undefined in
libboost_test_exec_monitor.a, but that's as far as I got.
I think, test_main is supposed to be defined by the test. Optionally,
Boost.Test could generate it if asked. I think you should define
BOOST_TEST_MODULE for that. I don't know if Boost.ASIO tests are supposed
to
work that way.
I'm a little confused where is BOOST_TEST_MODULE located? And should I
define this in the cpp code of the test itself?
It's a macro that should be defined before Boost.Test headers are included.
