Qt 5 / QtWebkit can make use of OpenSSL, which MinGW distributions do not ship.
 
==Pre-built packages==
 
The [http://slproweb.com/products/Win32OpenSSL.html Win32OpenSSL project] provides pre-compiled libraries for both 32 and 64 bit. However, these depend on the Microsoft Visual C++ 2008 runtime being installed.
 
Inside [[MSYS2]] shell, pre-built openssl can be obtained from MSYS2 repo, with this command: pacman -S openssl
 
==Compiling on your own==
 
===Requirements===
 
*Either use MSYS, or use [[MSYS2]] :
**MSYS shell command prompt (an sh shell + some UNIX tools, get it from http://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/msys-1.0.11/MSYS-1.0.11.exe/download?use_mirror=garr. It's also an (optional) part of mingw.org installer). Install it in C:drive in "msys" folder.
**[[MSYS2]] shell command prompt, it can be obtained from https://msys2.github.io/ Install it in C:drive in "msys2" folder.
*Working MinGW, or MinGW-w64 toolchain:
**Either get & load MinGW, or, get & load MinGW-w64 toolchains (from their respective project website), or, use "MinGW-w64" toolchains from MSYS2 repo, inside the MSYS2-shell.
**NOTE: Do not use (or try to avoid using) different type of toolchains for building different sub-components for the same/main project, when targeted for same platform/OS. If you are using MinGW-w64 based toolchains from MSYS2\mingw32 or MSYS2\mingw64, then for main project & all sub-components, use same MSYS2 toolchains. If you are using MinGW toolchain, then for all of your sub-components & main project, use same MinGW toolchain. If you are using MinGW-w64 toolchains from "MinGW-builds", then for all sub-components & main project, use same MinGW-builds toolchains.
 
===How to build===
 
*Download latest+stable [https://www.openssl.org/ OpenSSL] (You must use HTTPS secure encrypted connection to obtain source file) from https://www.openssl.org/source (e.g. openssl-1.0.1c.tar.gz)
*Either start MSYS-shell, or start MSYS2-shell:
**Start a MSYS shell command prompt (C:.0\msys.bat)
**Or, start MSYS2 shell command prompt (C:2\msys2_shell.bat)
***See inside this [[MSYS2]] page, how to prepare MSYS2 with build/compile related toolchains, tools & dependencies
 
*Extract source tar.gz using MSYS tar or MSYS2 tar (and ignore the symlink warnings)
**''don't use 7zip or other apps, since they fail to set up any symlinks! tar will also complain about symlinks, but compilation will still succeed.''
 
*Unzip/decompress source:
 
<code>
$ tar xvzf openssl-1.0.1c.tar.gz
$ cd openssl-1.0.1c
</code>
 
*Check that gcc is in PATH, otherwise add it: change below command to match with your-side directory's exact name & letter-case & location:
**If using MinGW-builds toolchain (which is usually located outside of MSYS or MSYS2), then execute this in MSYS or in MSYS2:
 
<code>
$ export PATH="/c/Mingw-builds/bin:$PATH"
</code>
 
**If using MSYS shell, and if you have installed MinGW toolchain into C:32 directory, then execute this:
 
<code>
$ export PATH="/c/mingw32/bin:$PATH"
</code>
 
**If using MSYS2 shell, execute this, if you are building for 32bit:
 
<code>
$ export PATH="/c/msys2/mingw32/bin:$PATH"
#or if using 64-bit MSYS2
 
$ export PATH="/c/msys64/mingw32/bin:$PATH"
 
</code>
 
**If using MSYS2 shell, execute this, if you are building for 64bit:
 
<code>
$ export PATH="/c/msys32/mingw64/bin:$PATH"
#or if using 64-bit MSYS2
 
$ export PATH="/c/msys64/mingw64/bin:$PATH"

Qt 5 / QtWebkit can make use of OpenSSL, which MinGW distributions do not ship.

Pre-built packages

The Win32OpenSSL project provides pre-compiled libraries for both 32 and 64 bit. However, these depend on the Microsoft Visual C++ 2008 runtime being installed.

Inside MSYS2 shell, pre-built openssl can be obtained from MSYS2 repo, with this command: pacman -S openssl

Compiling on your own

Requirements

  • Either use MSYS, or use MSYS2 :
  • Working MinGW, or MinGW-w64 toolchain:
    • Either get & load MinGW, or, get & load MinGW-w64 toolchains (from their respective project website), or, use "MinGW-w64" toolchains from MSYS2 repo, inside the MSYS2-shell.
    • NOTE: Do not use (or try to avoid using) different type of toolchains for building different sub-components for the same/main project, when targeted for same platform/OS. If you are using MinGW-w64 based toolchains from MSYS2\mingw32 or MSYS2\mingw64, then for main project & all sub-components, use same MSYS2 toolchains. If you are using MinGW toolchain, then for all of your sub-components & main project, use same MinGW toolchain. If you are using MinGW-w64 toolchains from "MinGW-builds", then for all sub-components & main project, use same MinGW-builds toolchains.

How to build

  • Download latest+stable OpenSSL (You must use HTTPS secure encrypted connection to obtain source file) from https://www.openssl.org/source (e.g. openssl-1.0.1c.tar.gz)
  • Either start MSYS-shell, or start MSYS2-shell:
    • Start a MSYS shell command prompt (C:.0\msys.bat)
    • Or, start MSYS2 shell command prompt (C:2\msys2_shell.bat)
      • See inside this MSYS2 page, how to prepare MSYS2 with build/compile related toolchains, tools & dependencies
  • Extract source tar.gz using MSYS tar or MSYS2 tar (and ignore the symlink warnings)
    • don't use 7zip or other apps, since they fail to set up any symlinks! tar will also complain about symlinks, but compilation will still succeed.
  • Unzip/decompress source:
$ tar xvzf openssl-1.0.1c.tar.gz
$ cd openssl-1.0.1c
  • Check that gcc is in PATH, otherwise add it: change below command to match with your-side directory's exact name & letter-case & location:
    • If using MinGW-builds toolchain (which is usually located outside of MSYS or MSYS2), then execute this in MSYS or in MSYS2:
$ export PATH="/c/Mingw-builds/bin:$PATH"
    • If using MSYS shell, and if you have installed MinGW toolchain into C:32 directory, then execute this:
$ export PATH="/c/mingw32/bin:$PATH"
    • If using MSYS2 shell, execute this, if you are building for 32bit:
$ export PATH="/c/msys2/mingw32/bin:$PATH"
#or if using 64-bit MSYS2

$ export PATH="/c/msys64/mingw32/bin:$PATH"
    • If using MSYS2 shell, execute this, if you are building for 64bit:
$ export PATH="/c/msys32/mingw64/bin:$PATH"
#or if using 64-bit MSYS2

$ export PATH="/c/msys64/mingw64/bin:$PATH"
  • Check that you have your PATH correctly setup
# should point to a mingw distribution of gcc

$ which gcc
/c/msys64/mingw32/bin/gcc
  • for MinGW (32 bit) do:
$ ./Configure --prefix=$PWD/dist no-idea no-mdc2 no-rc5 shared mingw
  • for MinGW-w64 do:
$ ./Configure --prefix=$PWD/dist no-idea no-mdc2 no-rc5 shared mingw64
  • Compile & install:
$ make depend && make && make install

Using it

  • If you are using cmd.exe (Cmd-shell), then: add the bin, include, lib folders to your compilation environment:
C:\> set PATH=PATH;C:\openssl1.0.1c\dist\bin
C:\> set INCLUDE=INCLUDE;C:\openssl1.0.1c\dist\include
C:\> set LIB=LIB;C:\openssl1.0.1c\dist\lib
  • If you are using MSYS2/MSYS-shell, then: add the bin, include, lib folders to your compilation environment:
$ export PATH="$PATH:/c/openssl-1.0.1c/dist/bin"
$ export INCLUDE="$INCLUDE:/c/openssl-1.0.1c/dist/include"
$ export LIB="$LIB:/c/openssl-1.0.1c/dist/lib"

When you now run Qt's configure.exe openssl should be detected, and Qt links against the libraries.
