Rebuild Qt Libraries

You can re-build the Unigine Qt libraries but it's not recommended for the Qt components to work properly.

Unigine SDK uses 5.4.1 and 5.6.1-1 versions of Qt:

Qt 5.4.1 is used for Unigine SDK Browser
Qt 5.6.1-1 is used for Unigine Editor

Preparation

Build ICU libraries:

Install cygwin
Download ICU source code

Build ICU with the following batch script, changing %CYGWIN_PATH% variable with the path where cygwin installed

Shell commands

set PATH=%CYGWIN_PATH%\bin;%PATH%
call %VS120COMNTOOLS%vsvars32.bat
:: for x64 build use:
:: call %VS120COMNTOOLS%..\..\VC\bin\x86_amd64\vcvarsx86_amd64.bat
cd icu/source
bash runConfigureICU Cygwin/MSVC --enable-static --disable-shared
nmake
nmake install

Build OpenSSL libraries:

Install perl
Download OpenSSL v1.0.2 source code

Build OpenSSL for x86, changing %PERL_PATH% variable with the path where perl installed

Shell commands

call %VS120COMNTOOLS%vsvars32.bat
set PATH=%PERL_PATH%\bin;%PATH%
cd openssl-1.0.2
call perl Configure VC-WIN32 no-shared no-asm
call ms\do_ms
nmake -f ms\nt.mak
nmake -f ms\nt.mak install

For building OpenSSL 64-bit version use the following script

Shell commands

call %VS120COMNTOOLS%..\..\VC\bin\x86_amd64\vcvarsx86_amd64.bat
set PATH=%PERL_PATH%\bin;%PATH%
cd openssl-1.0.2
call perl Configure VC-WIN64A no-shared no-asm
call ms\do_win64a
nmake -f ms\nt.mak
nmake -f ms\nt.mak install

Build

Download sources of Qt modules and unpack them:
- For 5.4.1 Qt build download:
- For 5.6.1-1 Qt build download:
  - qtbase-opensource-src-5.6.1-1.zip
  - qttools-opensource-src-5.6.1-1.zip

Build Qt base libraries with the script, setting variables %VERSION%, %ICU_PATH% and %OPENSSL_PATH% before

Shell commands

set QMAKESPEC=win32-msvc2013
call %VS120COMNTOOLS%vsvars32.bat
set PREFIX=%~dp0
set LIBDIR=%~dp0\lib
set INFIX=Unigine_x86
set PATH=%ICU_PATH%\bin;%PATH% 
set INCLUDE=%ICU_PATH%\include;%INCLUDE%
set LIB=%ICU_PATH%\lib;%LIB%
set INCLUDE=%OPENSSL_PATH%\include;%INCLUDE%
set LIB=%OPENSSL_PATH%\lib;%LIB%
cd qtbase-opensource-src-%VERSION%

nmake install

Build Qt UiTools library with previously built qmake tool

Shell commands

cd qttools-opensource-src-%VERSION%\src\designer\src
set QMAKESPEC=win32-msvc2013
call %VS120COMNTOOLS%vsvars32.bat
qmake
nmake
nmake install

Build Qt WebKit libraries. For Qt 5.4.1 only
1. Install ruby
2. Install GNUWin32
3. Install SQLite. For SQLite, download the 'amalgamation' sources and make sure you set SQLITE3SRCDIR environment variable to the directory containing the source files. (You could also set %SQLITE3SRCDIR% to the sources in your Qt's base source directory src/3rdparty/sqlite)
4. Build QtWebKit and QtWebKitWidgets libraries with the following batch script, changing variables with the real pathes
  Shell commands
```
set QMAKESPEC=win32-msvc2013
call %VS120COMNTOOLS%vsvars32.bat
set PATH=%CYGWIN_PATH%\bin;%PATH%
set PATH=%PERL_PATH%\bin;%PATH%
set PATH=%RUBY_PATH%\bin;%PATH%
set PATH=%GNUWIN32_PATH%\bin;%PATH%
set PATH=%ICU_PATH%\bin;%PATH%
set INCLUDE=%ICU_PATH%\include;%INCLUDE%
set LIB=%ICU_PATH%\lib;%LIB%
set SQLITE3SRCDIR=%SQLITE_PATH%

cd qtwebkit-opensource-src-5.4.1
call perl Tools\Scripts\build-webkit --qt --release --minimal
cd WebKitBuild\Release
call nmake install
```
