Ah, my misunderstanding, sorry. Since you were mentioning apt-get, I thought you were attempting to do something with WSL or MinGW. @hlu2021 recently posted steps that worked here ~ https://github.com/AcademySoftwareFoundation/openexr/issues/1374...

Thanks for bringing up vcpkg. I would also note that the vckpg build of OpenEXR is usually reasonably up to date. https://github.com/microsoft/vcpkg/blob/7a98b9a727175eae45ff198c413e382a68468e26/ports/openexr/portfile.cmake It seems logical that a vcpkg user would...

I think that's right, but I'm speculating without a way to try it out. Did you try narrowing it to `/EHs`, and did that resolve your problem? I'm also wondering...

Ok, thanks! cc/ @kdt3rd

you should be able to do this: ``` cd myProjectDir git clone https://github.com/AcademySoftwareFoundation/openexr mkdir openexr-build cd openexr-build cmake ../openexr -DCMAKE_INSTALL_PREFIX=./install ``` then build the using the generated build system files....

In general, you shouldn't see the error about Imath, because OpenEXR automatically installs Imath if it can't find it. To diagnose those sorts of problems, we'd need to know more,...

Even though it complains during configuration that Imath wasn't found, it will download it automatically when you build. Our messages should be better, instead of reporting an error, it should...

on second thought, your error messages show a problem with zlib symbols not being found. I do wonder if maybe cmake is finding the wrong zlib on your system somehow?...

Great! Glad it's working for you now. If there's any improvement you can think of for our build instructions that would have made the experience better for you, we'd be...

I would recommend reading the source code for the various tools in src/bin, or the examples in src/examples. For python, OpenImageIO might be a good place to explore. It will...
