throwErrno symbols missing when Iex is linked before other libraries statically

I'm not sure anything can be done about this, but in case someone else has this problem, I'll file it. I won't be offended if its closed :)

We got symbol errors when OpenEXR tried to throw an exception based on an errno. We linked OpenEXR statically and the link order was "Half Iex ...[rest]". This caused a symbol error when it tried to call throwErrno. By moving Iex to the end of the link order, we fixed this issue.

Yeah, I'm pretty sure this is standard linker behavior, symbols are searched for left to right. But to be clear - this link order is in your application Makefile, not from OpenEXR's build files, right?

[skurmedel]

Yeah, it was the order in our CMake scripts. Probably nothing OpenEXR can do about it.

Closing the issue for now, feel free to re-open or file a new issue if you need further help.
