Preface

This will guide you through using a PowerShell script to automatically download and compile Qt statically for you.

The install will default to C:\Qt\Static\{VERSION}\{PLATFORM} (e.g. C:\Qt\Static\5.8.0\msvc2017_64)

Prerequisites

MSVC
    -QtSrcUrl    (Default: "http://download.qt.io/official_releases/qt/5.8/5.8.0/single/qt-everywhere-opensource-src-5.8.0.7z")
    -QtVersion   (Default: "5.8.0")
    -QtRoot      (Default: "C:\Qt")
    -QtStaticDir (Default: "$QtRoot\Static")
    -QtToolsDir  (Default: "$QtRoot\Tools")
    -NumJobs     (Default: 12)
    -MSVC        (Default: 2017)
    -Arch        (Default: "x86") (Other: "amd64")
    -Release     (Default: "debug-and-release") (Other: "release")
  • If building for 64-bit, pass in -Arch amd64
  • To change number of jobs for CPU, pass in e.g. -NumJobs 8 (or your # of CPU cores)

Setting up PowerShell

  • Install PowerShell 3.0 or 4.0
  • Run PowerShell as Administrator
  • Enter:

    Set-ExecutionPolicy RemoteSigned
    ... and hit Return.

Building Qt

  • Run the script.

  • It will download the source package.

  • It will extract the source package to C:\Qt\src.

  • For MSVC, it will import your environment using the VS Command Prompt BAT file. Note: For VS 2017 they no longer create the necessary environment variables. If you do not have the file at C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat you will need to adjust the path in the file.

  • It will configure Qt, for example:

       cmd /c "configure.bat -static -debug-and-release -platform win32-msvc -prefix $QtDir `
   -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -qt-sql-sqlite -no-openssl `
   -opensource -confirm-license `
   -make libs -nomake tools -nomake examples -nomake tests"

  • It will compile Qt with N jobs where N = # of CPU threads. This will take anywhere from 1 hour to several hours.

  • It will install Qt to C:\Qt\Static\{VERSION}\{PLATFORM}.

  • After installing it will:

    • Patch CONFIG += static into the platform's qmake.conf
    • Patch the .prl files to point to the install directory
    • Create a qt.conf file in QTDIR\bin which defines the install location
    • Copy the .pdb files to the install dir if using a debug-and-release or debug configuration. It doesn't do this for whatever reason.

After it builds you can add the version manually inside Qt Creator at Tools > Build & Run > Qt Versions
