This page describes the process of configuring and building. Before building, there are some requirements that are given in more detail in the document. You can download the Qt 5 sources from the page.

If you are using a binary installer or the commercial Qt Creator, your licenses are automatically fetched and stored in your local user profile (%USERPROFILE% AppData Roaming Qt qtlicenses.ini file). If you do not use any binary installer or Qt Creator, you can download the respective license file from your Web portal and save it to your user profile as%USERPROFILE%.qt-license. If you prefer a different location or file name, you need to set the QT_LICENSE_FILE environment variable to the respective file path. Step 2: Unpack the Archive Uncompress the files into the directory you want Qt installed; e.g.

C: Qt%VERSION%. Note: The install path must not contain any spaces or Windows specific file system characters. Step 3: Set the Environment Variables We recommend creating a desktop link that opens a command prompt with the environment set up similar to the Command Prompt menu entries provided by the Windows SDKs. This is done by creating an application link passing a.cmd file setting up the environment and the command line option /k (remain open) to cmd.exe.

Assuming the file is called qt5vars.cmd and the Qt folder is called qt-5 and located under C: qt. REM Set up Microsoft Visual Studio 2017, where is c amd64, c x86, etc.

CALL 'C: Program Files (x86) Microsoft Visual Studio 2017 Professional VC Auxiliary Build vcvarsall.bat' SET _ROOT =C: qt qt - 5 SET PATH =%_ROOT% qtbase bin;%_ROOT% gnuwin32 bin;%PATH% REM Uncomment the below line when using a git checkout of the source repository REM SET PATH =%_ROOT% qtrepotools bin;%PATH% SET _ROOT = A desktop link can then be created by specifying the command%SystemRoot% system32 cmd.exe /E:ON /V:ON /k c: qt qt5vars.cmd as application and c: qt qt-5 as working directory. Note: Setups for are similar; they differ only in that the bin folder of the installation should be added to the path instead of calling the Windows SDK setup script. For, please make sure that no sh.exe can be found in the path, as it affects mingw32-make. Settings required by the additional libraries (see ) should also go this file below the call to the Windows SDK setup script. Step 4: Build the Qt Library The default behavior of configure is to create an in-source build of Qt 5.
