I'm trying to call a function from the windows platform libraries:

BCryptGenRandom

. At link time, I get

undefined reference to 'BCryptGenRandom'

. Here are the linker settings I have for my mingw test target:

targetFromPreset(presets.mingwX64, 'mingw') {
    compilations.test.linkerOpts '-Wl,--subsystem,windows,-L"C:\\Program Files (x86)\\Windows Kits\\10\\Lib\\10.0.17763.0\\um\\x64\\bcrypt.lib"'
}

I think I may have overdone it with the full path to bcrypt.lib there, but I'm trying everything. Any advice here would be appreciated! First time attempting to get my K/N code working for mingw. Thanks!

Mingw is not compatible with with libs in msvc format, please use libs from msys2-mingw64 distribution.

Ah! I’ll give that a try. Thanks!

no need to use lib file here, just

-lbcrypt

in linker options works for me. Technically, it’s a bug in platform libs, so we’ll fix it in upcoming releases.

Thanks I was just about to update that I got it working this way:

compilations.test.linkerOpts "-Wl,--subsystem,windows, -Bstatic -lbcrypt"

. I also happened to have just installed msys2 and the associated mingw-w64-x86_64-toolchain (installs the platform libs to

"C:\msys64\mingw64\lib"

). Did I need that, or would

-lbcrypt

have worked without installing those libs?

Ha! It's literally just bcrypt. Thanks for all of that!
