Ah, interesting. So that sounds like we should downgrade the version of fmt that is automatically downloaded when none is found locally -- currently 9.1, but we should use something older to ensure it can compile with all the gcc versions we claim to support.
And maybe we also should double check and warn if the fmt it found is not going to work with the gcc being used? Do you think those two changes would adequately address the problem? > On May 7, 2023, at 9:54 PM, Fabrice Macagno <fabrice.maca...@al.com.au> wrote: > > Hi there, this is more an FYI: fmt-9.1.0 > <https://github.com/OpenImageIO/oiio/blob/32a361ab3ed6479725f0b22d591a436728cfe640/src/cmake/externalpackages.cmake#L322> > cannot be built with gcc lesser than 7.3.
