iex_debugTrap link error

[rromerik]

when using adsk fbx lib & other lib that include your lib we get link error over debugTrap, any plan to fix that ?

You can get around the problem by defining your own iex_debugTrap() as

void iex_debugTrap() { std::cout << "what the heck" << std::endl; }

I suggest reporting this problem to Autodesk as the issue lies with the fbx distribution.

Looking into the OpenEXR issue backlog. Does not seem to be an OpenEXR issue, so closing.

Why the issue is not considered to be an OpenEXR issue?
iex_debugTrap is a part of Iex, which is a part of OpenEXR.
Issue is occurring when linking separate versions of libraries together, which is explicitly supported with namespace-mangling mechanism.
But iex_debugTrap is not namespaced, and that breaks promise, given by the library.

That is a good point about the namespacing introduced across the rest of the library to resolve these kinds of collisions. TBH iex_debugTrap should probably be removed. It's not a normal sort of thing to find in a modern library. I personally added this mechanism a loooooong time ago, when debuggers such as the Visual Studio debugger were unable to break when exceptions were thrown. Those days are long gone, and the mechanism is archaic.
