I'm trying to build ICU 72 for Windows. I got the source (ICU4C) from the GitHub repo and built the project with Visual Studio 2019 by following the steps outlined on the ICU website. I also ran the tests as specified on the website, and all of them pass.
However, when I check the content of icu/bin, the .dll files are suspiciously tiny. In particular, icudt72.dll is only 3KB whereas its counterpart in the binary distribution is over 30MB.
This is an issue for me as I am trying to call icu::Normalizer2::getNFKCInstance() in my code but am getting U_FILE_ACCESS_ERROR. I suspect that this could be due to one of the ICU .dlls being incomplete and not including the normalizer.
I cannot simply use the ICU binaries distributed on the ICU GitHub as I am building with custom build settings. I thought that the small .dll file were because of my build settings, but it turns out that a fresh (unmodified) copy of the source builds into those tiny .dlls as well.
I imagine that there's something in the process I missed, but I can't figure out what. Can anyone lend me a hand? Thanks!!
