Cannot build library with OpenImageIO multimedia engine using MinGW 64

[C010UR]

While trying to build libs using mingw, i get the error below. I used following cmake options: USE_DOCTEST=off USE_PANDOC=off BUILD_EXECUTABLES=off USE_MULTIMEDIA=oiio. Using ffmpeg instead of OpenImageIO helps, but perfomance is bad and the demo breaks after the penguin scene.

I enjoy nothing more than large C++ diagnostics! let me see if i can figure out what's going on; thanks for the report!

ooh and it's mingw, too. yes, i recall regular problems with OpenImageIO on the windows platform. ok, i'll need build back up some context to look into this. i think i only support ffmpeg on windows? maybe it's the other way around, though.

This make it build, but is it also separated to two libs on other platforms? https://packages.msys2.org/package/mingw-w64-ucrt-x86_64-openimageio?repo=ucrt64

oooh i don't know!

[dankamongmen]

looks like yes on Linux. on those platforms, we get the library names from pkg-config, which lists all necessary ones.

we would probably need a corresponding notcurses-static line.
