Cast to what? init function has right signature.

Greg > The cast is right above you. Yes the signature matched- bool return; void arguments. But VS2008 still complained that I could not pass that into unit_test_main.  The cast worked fine, the function got called no problem.

What the error message?

Greg> "Invalid test unit type" . ?!

Since I was debugging the program, it stopped on the exception. If I just let it run, that's pretty much the error message. What does that message mean? Somewhere else I saw on the net that it could mean there is no test suite defined but I am hoping I don't need to do that.

Please post simple example. I do not follow what is your problem. By the
way what version of Boost r u using?

Greg > 1.38 as the subject says.  TestMain is simply a function that returns an int and gets passed a void. I trust the above line is the correct way to add such a function?

This issue fixed since. And it was just an issue with proper error report.

No you don't.

Greg> good.

To summarize:
-The framework is throwing saying "Invalid unit test type"
-I am not defining suites or test cases other than the code you've seen which manually adds them using master_test_suite.add()
-Boost is 1.38

Since I haven't really defined a unit test other than to pass a function, maybe there is some step I need to take?
