== Compiling OpenSSL with MinGW or MinGW-w64 ==
Qt 5 / QtWebkit can make use of OpenSSL, which MinGW distributions do not ship.
== Pre-built packages ==
The &quot;Win32OpenSSL project&amp;quot;:http://slproweb.com/products/Win32OpenSSL.html 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 &quot;msys&amp;quot; folder.
** [[MSYS2]] shell command prompt, it can be obtained from https://msys2.github.io/ Install it in C:drive in &quot;msys2&amp;quot; folder.
* Working MinGW, or MinGW-w64 toolchain:
** Either get &amp; load MinGW, or, get &amp; load MinGW-w64 toolchains (from their respective project website), or, use &quot;MinGW-w64&amp;quot; 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 &amp; all sub-components, use same MSYS2 toolchains. If you are using MinGW toolchain, then for all of your sub-components &amp; main project, use same MinGW toolchain. If you are using MinGW-w64 toolchains from &quot;MinGW-builds&amp;quot;, then for all sub-components &amp; main project, use same MinGW-builds toolchains.
=== How to build ===
* Download latest+stable &quot;OpenSSL&amp;quot;:https://www.openssl.org/ (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 &amp; 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:<br /><code><br />&amp;#36; tar xvzf openssl-1.0.1c.tar.gz<br />&amp;#36; cd openssl-1.0.1c<br /></code>
* Check that gcc is in PATH, otherwise add it: change below command to match with your-side directory's exact name &amp; letter-case &amp; location:
** If using MinGW-builds toolchain (which is usually located outside of MSYS or MSYS2), then execute this in MSYS or in MSYS2:<br /><code><br />&amp;#36; export PATH=&quot;/c/Mingw-builds/bin:&amp;#36;PATH&amp;quot;<br /></code>
** If using MSYS shell, and if you have installed MinGW toolchain into C:32 directory, then execute this:<br /><code><br />&amp;#36; export PATH=&quot;/c/mingw32/bin:&amp;#36;PATH&amp;quot;<br /></code>
** If using MSYS2 shell, execute this, if you are building for 32bit:<br /><code><br />&amp;#36; export PATH=&quot;/c/msys2/mingw32/bin:&amp;#36;PATH&amp;quot;<br /></code>
** If using MSYS2 shell, execute this, if you are building for 64bit:<br /><code><br />&amp;#36; export PATH=&quot;/c/msys2/mingw64/bin:&amp;#36;PATH&amp;quot;<br /></code>
* for MinGW (32 bit) do:<br /><code><br />&amp;#36; ./Configure —prefix=&amp;#36;PWD/dist no-idea no-mdc2 no-rc5 shared mingw<br /></code>
* for MinGW-w64 do:<br /><code><br />&amp;#36; ./Configure —prefix=&amp;#36;PWD/dist no-idea no-mdc2 no-rc5 shared mingw64<br /></code>
* Compile &amp; install:<br /><code><br />&amp;#36; make depend &amp;&amp; make &amp;&amp; make install<br /></code>
== Errors ==
* If you run into<br /><code><br />perl asm/sha1-x86_64.pl mingw64 &gt; sha1-x86_64.s<br />gcc -I.. -I../.. -I../modes -I../asn1 -I../evp -I../../include -D_WINDLL -DOPENSSL_PIC -DOPENSSL_TH<br />READS -D_MT -DDSO_WIN32 -DL_ENDIAN -O3 -Wall -DWIN32_LEAN_AND_MEAN -DUNICODE -D_UNICODE -DOPENSSL_IA<br />32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM <s>DSHA256_ASM</s><br />DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM -c -o sha1-x86_<br />64.o sha1-x86_64.s<br />sha1-x86_64.s: Assembler messages:<br />sha1-x86_64.s:1824: Warning: end of file not at end of a line; newline inserted<br />sha1-x86_64.s:2183: Error: number of operands mismatch for `rol'<br />make[2]: '''* [sha1-x86_64.o] Error 1<br />make[2]: Leaving directory `/d/dev/tmp/openssl-1.0.1c/crypto/sha'<br />make[1]:'''* [subdirs] Error 1<br />make[1]: Leaving directory `/d/dev/tmp/openssl-1.0.1c/crypto'<br />make: '''* [build_crypto] Error 1<br /></code>
<br />''' check out http://openssl.6102.n7.nabble.com/Compile-error-with-MinGW-w64-td36657.html<br />'''* Use perl inside MSYS or inside MSYS2<br />'''* or change crypto/perlasm/x86_64-xlate.pl as mentioned in the e-mail thread.
== Using it ==
* If you are using cmd.exe (Cmd-shell), then: add the bin, include, lib folders to your compilation environment:<br /><code><br />C:gt; set PATH=PATH;C:–1.0.1c\dist\bin<br />C:gt; set INCLUDE=INCLUDE;C:–1.0.1c\dist\include<br />C:gt; set LIB=LIB;C:–1.0.1c\dist\lib<br /></code>
* If you are using MSYS2/MSYS-shell, then: add the bin, include, lib folders to your compilation environment:<br /><code><br />&amp;#36; export PATH=&quot;&amp;#36;PATH:/c/openssl-1.0.1c/dist/bin&amp;quot;<br />&amp;#36; export INCLUDE=&quot;&amp;#36;INCLUDE:/c/openssl-1.0.1c/dist/include&amp;quot;<br />&amp;#36; export LIB=&quot;&amp;#36;LIB:/c/openssl-1.0.1c/dist/lib&amp;quot;<br /></code>
When you now run Qt's configure.exe openssl should be detected, and Qt links against the libraries.
