It would help if you translate the error message. Can you clarify again with object files have conflicts?
Every file has the issue if BOOST_TEST_DYN_LINK is not defined for the file.
singleton<T>::instance is static method of the template defined in header file. Should be resolved by compiler.
That is what I thought as well.
I don't have an access to this compiler at the moment, so can't reproduce this.
On a side note, there is no multi-file Boost.Test example.
There is one: unit_test_example_09
Sorry I missed that one, although I tried to check every one. On a side note, BOOST_TEST_MAIN must be defined so that the main() function is instanciated, BOOST_TEST_MODULE is not enough (one could think so, and I did, reading the content of test_example_09_2.cpp Matthieu -- French PhD student Website : http://matthieu-brucher.developpez.com/ Blogs : http://matt.eifelle.com and http://blog.developpez.com/?blog=92 LinkedIn : http://www.linkedin.com/in/matthieubrucher
