[Boost-users] a question regarding automatic test module registration

Hi,

I'm trying to use the boost unit test framework, and I have a question 
regarding automatic test module registration and the automatic 
definition of the init_unit_test_suite() function.

I'm organizing unit tests into a range of source files:

tests1.cpp
tests2.cpp

where each file is set up as follows:

#define BOOST_TEST_MODULE moduleX
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(test1) { ... }
BOOST_AUTO_TEST_CASE(test2) { ... }

and I'm linking this all with -lboost_unit_test_framework-mt 
-lboost_test_exec_monitor-mt

Intersestingly, as soon as I have two or more test module files, I get 
the following linker error:

/usr/include/boost/test/unit_test_suite.hpp:187: multiple definition of 
`init_unit_test_suite(int, char**)'
debug/testGeometry.o:/usr/include/boost/test/unit_test_suite.hpp:187: 
first defined here

This seems to be a bit counter-intuitive - after all, isn't one supposed 
to be able to use a number of test modules as above? (for me, 
intuitively, yes :)

but if this is not the intended way of using the boost unit test 
library, how would one go about this using auto-registration? it would 
be really nice to spare the hassle of manual registration, but still be 
able to partition test cases into separate modules / files.
