Re: [Openexr-user] exrdisplay compile woes on Redhat 7.3

[Drew Hess]

Yikes, that looks like a gcc bug.  I wasn't able to reproduce that on my 
RedHat 7.2 system with gcc 2.96, though.  What version of gcc 2.96 RPM are 
you using?  Mine is gcc-2.96-98.

Also, try this: #include <ImathMath.h> and change the pow () function on 
line 85 to Math::pow<float> () and see if that fixes the problem.
