Building Erlang on Windows - crypto fails

[Matt Myers]

Hello,
I've been able to successfully build Erlang from master (OTP 24 rc0) on
Windows, but the crypto module is always failing (see note below).
I've built OpenSSL 1.1.1g successfully, and a test application built in C
works OK.

Would it be possible to get the config options used in building the
official Windows release of Erlang? Or where can I go to find that?
Maybe there is something simple that I'm missing.

Here are the options I'm using:

> --host=win32
> --enable-sctp
> --enable-smp-support
> --enable-threads
> --enable-builtin-zlib
> --enable-dynamic-ssl-lib
> --with-ssl=/c/build/openssl/release/1.1.1g
> --disable-hipe
> --disable-kernel-poll
> --disable-fp-exceptions
> --without-javac
> --with-wxdir=/c/opt/local64/pgm/wxWidgets-3.1.3/lib/vc_x64_lib
>

Also, I must say, building on Windows seems much improved from previous OTP
versions. The fact that Visual Studio 2019 is working is a big help. Many
thanks to whoever did that!

Thanks and best regards,
Matt
