Which openssl version are you using?

[StFlorian]

cd openssl-src-folder
perl Configure VC-WIN32 no-asm --prefix=C:\Qt\VS2015\openssl
ms\do_ms
nmake -f ms\ntdll.mak
nmake -f ms\ntdll.mak install

I cannot find the files in the ms/ folder. Which version is the readme based on?

We want to build Qt-4.8.7 on windows with msvc 140 and we see on ubuntu-18.04:

:~$ dpkg -l | egrep -wi '(libqt4-dev|libssl-dev|zlib1g-dev)' | awk  '{ print $2 " v" $3}'
libqt4-dev v4:4.8.7+dfsg-7ubuntu1
libqt4-dev-bin v4:4.8.7+dfsg-7ubuntu1
libssl-dev:amd64 v1.1.1-1ubuntu2.1~18.04.23
zlib1g-dev:amd64 v1:1.2.11.dfsg-0ubuntu2.2

Sorry, I changed job and haven't build those in the last 5 years !
I guess it should work with the same OpenSSL version that is the default one on ubuntu 18.04.
