Hello,
Fedora Linux is applying a bunch of patches to ilmbase which probably
should be included / reviewed upstream:
ilmbase-1.0.3-secondary.patch
# the FPU exception code is x86 specific - This should fix building on
# no-x86 archs.
ilmbase-1.0.3-ucontext.patch
# fix build on i686/32bit
# https://github.com/openexr/openexr/issues/3
They also revert the soname bump in 1.0.3:
# revert soname bump
# upstream missed bumping to so7 for OpenEXR-1.7.0, decided to do so now for
# OpenEXR-1.7.1. given fedora has shipped OpenEXR-1.7.0 since f15, bumping
# ABI now makes little sense.
Even with these patches ilmbase testsuite still fails on ix86, though.
