Re: [Openexr-devel] exrdisplay compliation fails

[Florian Kainz]

I haven't tried 4.0.3, but OpenEXR does compile with a variety
of different versions of gcc.  Versions 3.0 and later should
work.  The error you are getting does look like a problem with
the either the limits header or the bits/cpp_type_traits.h
header file.

You may want to take a look at file config/OpenEXRConfig.h
in your OpenEXR source directory, and check if it defines any
macros that are referenced in limits or bits/cpp_type_traits.h.
