How to build Qt 5.15 Community against OpenSSL 3

How to build Qt 5.15 Community with OpenSSL 3

The Qt v5.15 Community doesn't support OpenSSL 3 by default. You will face some issues at runtime if you attempt to build it with OpenSSL 3. This gist explains how to do it by yourself.


  1. Apply two attached patches
  2. Install OpenSSL 3
  3. Config the Qt with installed OpenSSL like this:
 ..\configure -prefix h:\mousavi\Qt\5.15.10\win32-msvc2019-x86 -debug-and-release -skip qtwebengine -openssl-runtime OPENSSL_PREFIX="H:\mousavi\OpenSSL-Win32"`

Qt 5.15 available configure options
Usage: configure [options] [assignments]
Configure understands variable assignments like VAR=value on the command line.
Each uppercased library name (obtainable with -list-libraries) supports the
_LIBS, and - on Windows and Darwin - _LIBS_DEBUG and _LIBS_RELEASE. E.g.,
ICU_PREFIX=/opt/icu42 ICU_LIBS="-licui18n -licuuc -licudata".
It is also possible to manipulate any QMAKE_* variable, to amend the values
from the mkspec for the build of Qt itself, e.g., QMAKE_CXXFLAGS+=-g3.
