Question

How do I define my own main() function when testing with boost?

Boost is using it’s own main function, but I’m using a custom memory manager and it needs to be initialized before any memory is allocated, otherwise I’ll get errors.

I do not believe you actually need your own main. I think you are much better off with global fixture:

struct AllocatorSetup {
    AllocatorSetup()   { /* setup your allocator here */ }
    ~AllocatorSetup()  { /* shutdown your allocator/check memory leaks here */ }
};

BOOST_GLOBAL_FIXTURE( AllocatorSetup );
