zint/win32

Visual Studio 2017
------------------

To build the zint library DLL and the command line tool "zint.exe" with PNG
support for x86/Win32:

Install git (https://git-scm.com/downloads)
Install cmake (https://cmake.org/download/)

Open a "Developer Command Prompt for VS 2017" (should be available under the
"Visual Studio 2017" tab in the Start menu).

Make sure git and cmake are in your PATH, e.g. (your paths may differ)

  set "PATH=C:\Program Files\Git\cmd;%PATH%"
  set "PATH=C:\Program Files\CMake\bin;%PATH%"

Download zint, zlib and libpng by going to the directory you want to clone them
into:

  cd <project-directory>

and cloning each:

  git clone https://git.code.sf.net/p/zint/code zint
  git clone https://git.code.sf.net/p/libpng/code lpng
  git clone https://github.com/madler/zlib.git zlib

First build zlib:

  cd zlib

  nmake -f win32\Makefile.msc LOC="-DASMV -DASMINF=" OBJA="inffas32.obj match686.obj"

  cd ..

and then lpng:

  cd lpng

  cmake -G"Visual Studio 15 2017"^
        -DCMAKE_BUILD_TYPE=Release^
        -DPNG_BUILD_ZLIB=ON^
        -DZLIB_INCLUDE_DIRS=..\zlib^
        -DPNG_STATIC=ON^
        -DPNG_SHARED=OFF^
        -H.^
        -Bbuild

  cmake --build build --config Release

  cd ..

If you now open "<project-directory>\zint\win32\zint.sln" with Visual Studio
2017, you should be able to build the Release configuration for Win32.

"zint.dll" and "zint.exe" will be in "<project-dir>\zint\win32\Release".

To build Zint Studio ("qtZint.exe"), you need to have Qt installed, which
involves signing up for a Qt account and installing the Qt Maintenance Tool.
Using this tool you can install various versions of Qt and various optional
components.

The following requires the "MSVC 2017 32-bit" component to be installed.

As of writing Qt 5.14.2 is the latest release that includes this component and
is used here. Add the location of this component to your PATH, e.g. (your path
may differ):

  set "PATH=C:\Qt\5.14.2\msvc2017\bin;%PATH%"

Next build the zint backend Qt library:

  cd zint\backend_qt

  qmake backend_qt_zintdll.pro
  nmake clean
  nmake release

  cd ..\..

Then "qtZint.exe":

  cd zint\frontend_qt

  qmake frontend_qt_zintdll.pro
  nmake clean
  nmake release

  cd ..\..

This creates "<project-directory>\zint\frontend_qt\release\qtZint.exe". It
requires the zint DLL to run, so add its location to your PATH:

  set "PATH=<project-directory>\zint\win32\Release;%PATH%"

You should now be able to run Zint Studio:

  zint\frontend_qt\release\qtZint


Visual Studio 2015
------------------

The solution and project files for Visual Studio 2015 have been moved to the
sub-directory vs2015 and are no longer maintained. However by copying the steps
above and adapting the settings from the Visual Studio 2017 project files (and
adding any sources missing), they should be pretty serviceable.

For information on building a standalone version of Zint Studio using Visual
Studio 2015, see "frontend_qt/howto_build_qzint_using_msvs2015.txt"
