How I built QT 5.11.1 for Android on Windows

I tried to build QT 5.11.1 for Android on Windows, and “configure.bat” completed successfully, but “mingw32-make” failed with with the following error:

No rule to make target 'vulkan/qvulkanfunctions_p.h', needed by '.obj\qvulkaninstance.obj'.

It is the bug fixed in QT 5.11.2 that is planned on August/September 2018.

When I build the master branch and copied the following files from it to \qtbase\src\gui\vulkan manually:

qvulkanfunctions.h
qvulkanfunctions_p.cpp
qvulkanfunctions_p.h

and started “mingw32-make” again I got another error:

How I compiled OpenSSL from sources with VS2015

I installed Perl, downloaded and extracted OpenSSL 1.1.0h and built 64 bit version in VS2015 x64 Native Tools Command Prompt with the following commands:

set PATH=%PATH%;C:\Perl64\bin
perl Configure VC-WIN64A no-asm
nmake

32 bit version can be built with VC-WIN32 configuration option as described in INSTALL:

on Windows (only pick one of the targets for configuration):
    $ perl Configure { VC-WIN32 | VC-WIN64A | VC-WIN64I | VC-CE }
    $ nmake
    $ nmake test
    $ nmake install

probably ‘A’ suffix means AMD and ‘I’ means something else, so we need ‘A’.

Regular expressions for editing DEF-file (Windows Module-Definition file)

The following regular expression (find/replace pair) in Visual Studio format removes extra whitespace and @ symbol from a DEF-file:

^[ \t]+(\b(?<name>_\w+|[\w-[0-9_]]\w*)\b)[ \t]+@(?<index>\d+)(?=\r?$)
${name}\t${index}

and converts it to such a form when it can be imported to MS Excel and sorted by the function number, so you can manually add new functions by incrementing the last number.

To convert the file back the following find/replace pair can be used:

^(\b(?<name>_\w+|[\w-[0-9_]]\w*)\b)[ \t](?<index>\d+)(?=\r?$)
\t${name}\t\t@${index}

Setting up QT Creator 4.6.1 for Android development on Windows 10

First I installed Android Studio. When it started I set an option to create the application with Native C++ support and Android NDK was automatically installed to C:\Users\AppData\Local\Android\Sdk\ndk-bundle, also I added Android-19 API level and somehow CMake was installed to C:\Users\AppData\Local\Android\Sdk\cmake\3.6.4111459. Then in QT Creator I opened Tools->Options->Devices->Android and specified the following paths:

Building QT 5.10.1 from sources with VS2017

I am not sure it is a correct way, but I was able to do this:

git clone --recursive https://code.qt.io/qt/qt5.git --branch v5.10.1

and all the submodules were checked out with commit hashes tag v5.10.1 points to:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
...
Submodule path 'qt3d': checked out '31f424bb81cd2583920d3d521e1e01f01c2d28e2'

Generating .NET wrappers for COM during build in MS Visual Studio

If in some Visual Studio solution a .NET project references a C++ project that implements a COM server then the following command can be used in Post-Build Event of the C++ project to generate .NET wrapper for COM:

"$(TargetFrameworkSDKToolsDirectory)tlbimp.exe" "$(TargetPath)" /verbose /strictref /asmversion=$(Version) /out:"$(TargetDir)$(TargetName)Lib.dll"

In VS2015 by default this command will generate .NET 4.0 assembly. To generate .NET 2.0 assembly, the following command can be used:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\TlbImp.exe" "$(TargetPath)" /verbose /strictref /asmversion=$(Version) /out:"$(TargetDir)$(TargetName)Lib.dll"

I am not sure that changing TargetFrameworkVersion attribute in PropertyGroup Label=”Globals” element of the project file can help here, so it is not clear how to get rid of absolute path.

Also it is impossible to add a reference to a TLB or EXE file to .NET assembly, so using TLB generated by MIDL directly is not an option (MIDL->Output page of C++ project using $(OutDir)$(TargetName).tlb as Type Library name).

How to remove APPX package installed by another user.

There is new optionĀ ‘-AllUsers’ in Windows 10 1709 so ‘LinesGame’ APPX package, for example, can be removed for all users with the following command:

Get-AppxPackage -all *lines*
Get-AppxPackage -all *lines* | Remove-AppxPackage -AllUsers

the first line outputs this:

How to run WIX bootstrapper application UI with elevated privileges?

WIX bootstrapper application (BA) can easily determine if it runs as admin with the following code:

using System;
using System.Diagnostics;
using System.Security.Principal;

static bool IsAdmin()
{
    WindowsIdentity id = WindowsIdentity.GetCurrent();
    WindowsPrincipal principal = new WindowsPrincipal(id);
    return principal.IsInRole(WindowsBuiltInRole.Administrator);
}

and if it does not, run a new instance as admin and exit:

static void RunAsAdmin()
{
    ProcessStartInfo proc = new ProcessStartInfo
    {
        UseShellExecute = true,
        WorkingDirectory = Environment.CurrentDirectory,
        FileName = Process.GetCurrentProcess().MainModule.FileName,
        Verb = "runas"
    };

    Process.Start(proc);
}

A simple WIX installer that runs custom actions on install and uninstall.

Below I provided the source code of WIX installer that shows the license, installation directory and runs custom actions on install and uninstall:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

        <Property Id="WIXUI_INSTALLDIR" Value="INSTALLFOLDER" ></Property>
        <WixVariable Id="WixUILicenseRtf" Overridable="yes" Value="License.rtf"/>
        <UIRef Id="WixUI_InstallDir"/>

        <InstallExecuteSequence>
            <Custom Action="InstallService" After="InstallFiles">(NOT Installed) AND (NOT REMOVE)</Custom>

        <CustomAction Id="InstallService" Return="check" Impersonate="yes" Execute="deferred" Directory="INSTALLFOLDER" ExeCommand="[INSTALLFOLDER]$(var.MyService.TargetFileName) parameters..."/>

    </Product>
    ...
</Wix>

MyService is project referenced by my wixproj in VS2015. If Impersonate=”yes” the command is run as the current user, if “no”, the command is run as “NT AUTHORITY\SYSTEM“. INSTALLFOLDER is defined as follows:

Installing Google Play Services on a Windows 10 with MS VS2015

If Android support is enabled in MS VS2015, it installs Android SDK without Google Play Services and I did not find an option in SDK Manager that installs them. When I started “C:\Program Files (x86)\Android\android-sdk\SDK Manager.exe” with admin privileges, it automatically offered to install some 9 packages:
