Thanks Thiago.

Has anybody built qt5.5.0 from sources with MSVC2015?

There are people on the list that will want to build qt5.5.0 and qt5.5.1 if
we must wait until qt5.6 to get a MSVC2015 binary build
using Windows 10.

So I would like to document a HOWTO for people in the community to repeat
step-by-step to build Qt5.5.0 from sources.

I did try to compile from qt.5.5.0 sources and ran into openssl path
errors.  Once I solve the openssl problems, I will likely run into others.
Building from sources
is trivial when everything goes right.

Since openssl is needed and it does not come standard on a Windows machine,
and since there is no "yum install openssl" on Windows 10, I found
a MSVC2015 compiled developer ready package for the latest library and
header files from the following link:

http://p-nand-q.com/programming/windows/openssl-1.0.2d-32bit-release-dll-vs2015.7z

Unzipped an put into: C:\macdev\openssl  directory

For those who want more security, build your openssl from sources.  But
that is not the goal here, we want to compile qt5.5.0 from sources using
MSVC2015 Community edition.

Using the git configure as a guide, I tried to do emulate as close as
possible the binary package build:

http://code.qt.io/cgit/qtsdk/qtsdk.git/tree/packaging-tools/releases/release-55?h=v5.5.0-packaging

The closest config I could find was:

-opensource -confirm-license -debug-and-release -release -nomake tests
-nomake examples -qt-zlib -qt-libjpeg -qt-libpng -opengl dynamic
-plugin-sql-mysql -plugin-sql-psql -plugin-sql-sqlite -plugin-sql-odbc
-openssl -target xp -dbus

So I removed the -target xp and removed some database stuff since I don't
need it)
Added in a platform option to point to the correct mkspec.

Here is my shadow build batch file:
***************************************************
mybuild.bat
REM A script file to build
mkdir C:\macdev\qt550\2015build
cd C:\macdev\qt550\2015build

REM Make sure you go grab a beer at Moe's with Homer before checking if the
build is finished

REM just clean things up before building again
nmake clean

REM OPENSSLBUILD -> Here is my openssl version (this fails with openssl.h
path errors (copied below))
REM C:\macdev\qt550\src\configure -opensource -confirm-license -prefix
C:\macdev\qt550\msvc2015x86 -opensource -debug-and-release -release -nomake
tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -opengl dynamic
-dbus REM -platform win32-msvc2015 -openssl -I C:\macdev\openssl\ -I
C:\macdev\openssl\include\ -I C:\macdev\openssl\include -L
C:\macdev\openssl -L C:\macdev\openssl\bin -L C:\macdev\openssl\lib

REM NOOPENSSLBUILD -> If it will not build with openssl, how will it work
without openssl as a test?  (Try below)
C:\macdev\qt550\src\configure -opensource -confirm-license -prefix
C:\macdev\qt550\msvc2015x86 -opensource -debug-and-release -release -nomake
tests -nomake examples -qt-zlib -qt-libjpeg -qt-libpng -opengl dynamic
-dbus -platform win32-msvc2015 -no-openssl -no-ssl
<http://p-nand-q.com/programming/windows/openssl-1.0.2d-32bit-release-dll-vs2015.7z>

REM Now Compile
jom

MANY SSL ERRORS ABOVE - But the net result:
c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_p.h(185): error
C2061: syntax error: identifier 'QSslCertificate'
c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_p.h(199): error
C3646: 'sessionCipher': unknown override specifier
c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_p.h(199): error
C2059: syntax error: ')'
c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_p.h(199): error
C2238: unexpected token(s) preceding ';'
c:\macdev\qt550\src\qtbase\src\network\ssl\qsslsocket_openssl_p.h(75):
fatal error C1083: Cannot open include file: 'openssl/asn1.h': No such file
or directory

What?

My -no-openssl and -no-ssl should beg the question why Qt build process
wants openssl.

Cheers all,
