GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. For instructions on how to set up the Qt Creator repository to contribute patches back to Qt Creator, please check:.

This section provides step by step instructions for compiling the latest versions of Qt and Qt Creator on Windows. If you plan to contribute to Qt Creator, you should compile your changes with both compilers.

If you plan to use the MinGW compiler suite, do not choose to put git in the default path of Windows command prompts.

Building Qt Documentation

For more information, see step 9. If you plan to use MinGW accã¸s ã  linformation Microsoft Visual Studio simultaneously or mix different Qt versions, we recommend creating a directory structure which reflects that.

Run perl -v to verify that the version displayed is 5. Note that git ships an outdated version 5. You should now have the directories qt and creator under your working directory.

We strongly recommend using the bit version and bit compilers on bit systems. It is a replacement for nmake that utilizes all CPU cores and thus speeds up compilation significantly.

For convenience, we recommend creating shell prompts with the correct environment. This can be done by creating a. You can create desktop links to the. That should result in a sh is not recognized as internal or external command If a sh. You have to remove it from the path.This page describes the process of configuring and building Qt for Windows. Before building, there are some requirements that are given in more detail in the Qt for Windows - Requirements document.

You can download the Qt 5 sources from the Downloads page. For more information, visit the Getting Started with Qt page. If you have the commercial edition of Qt, copy the license file from your account on the distribution server into your home directory this may be known as the userprofile environment variable and rename it to. This renaming process must be done using a command prompt on Windows, not with Windows Explorer. Uncompress the files into the directory you want Qt installed; e.

Note: The install path must not contain any spaces or Windows specific file system characters.

Qt Documentation

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. Assuming the file is called qt5vars. Note: Setups for MinGW 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 MinGWplease make sure that no sh. Settings required by the additional libraries see Qt for Windows Requirements should also go this file below the call to the Windows SDK setup script. The default behavior of configure is to create an in-source build of Qt 5. Alternatively, the command line option -developer-build creates an in-source build for developer usage. To configure the Qt library for a debug build for your machine, type the following command in the command prompt:.

The Configure Options page contains more information about the configure options. If an installation prefix was given, type jom installnmake install or mingwmake install.

Note: If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing nmake distclean before running configure again.

Step 1: Install the License File Commercial Editions Only If you have the commercial edition of Qt, copy the license file from your account on the distribution server into your home directory this may be known as the userprofile environment variable and rename it to.Prerequisites Assumptions means Prerequisites for this process are the following:. Make sure to get the latest version of each one of dependencies mentioned above, apart from the ones which are explicitly mentioned.

If you are sure about the prerequisites mentioned above, then just proceed with the instructions. Just so that we have an example case during this tutorial, I will assume 5.

How To Build Qt Creator From Source

As it was mentioned in the Prerequisites section, if you are on Windows, you must add the following to the PATH This is only required in Windows for taking care of bison, flex and gperf binaries :.

After that, switch to the folder where you extracted the source files from the link above, using the command below:. Wait until you are presented with the following:. Configuration Examples Below are some example configure commands that you can use for building Qt with various configurations:. Static build, the recommended way since QtWebEngine does not support static linking at the moment :. Look for the following codes in msvc-desktop.

You can also refer to the following link for a complete list of requirements and possible build customization on all platforms:. Thank you for the detailed steps to build Qt statically for windows, i did the same and builded successfully. Now i want to build it on Mac OS version Kindly suggest the Qt version that could be suitable for mojave and build steps.

The build steps mentioned in this post are universal and with little or no modifications you should be able to use them on Windows, macOS and Linux alike. Generally speaking, you need to have the dependencies python, perl, bison, flex and so on and run the following commands:. Obviously you can pass parameters like -prefix and so on to customize the configure command. Regarding the Qt version, as a rule, you can always go for the latest Qt version or if you want to be on the safe side, go for the latest LTS version of Qt which at the moment is 5.

Thank you, i have build and generated the qmake with the above steps using Qt 5. What exactly are you trying to achieve? Do you want to build Qt Installer Framework from scratch? Thank you for your time. I have downloaded the pre built QT Installer Framework 3. But when i try to install this application installer on Mac Book air After waiting for so long time i did force quit. I did not understand what could be the problem and how to fix it.

This hang is not happening all the time. Check your installer scripts, try a simple installer. Try the simplest example installer out there and if you can get it to work, then start changing your script the way you need.

You can use VS Code or even write your own set of scripts using Notepad and without using any professional code editor, as long as you have the necessary requirements for building Qt from sources.

What would you recommend? Just make sure the compiler and the kit are checked during the installation. Hi, thank you for the tutorial, is very helpful!

I have one question. In Windows, Qt needs bison, flex and GPerf in PATH to build some libraries, so after installing Qt, can I delete the source files or there will be problems with the dependencies metioned above?If you have Qt installed, you probably have all the other dependencies of Qt Creator, too.

There are numerous Qt Creator plugins, and they may require additional packages to be installed but they usually don't block the compilation, so don't worry. If you do not want to include the Qbs plugin, you'll need to omit --recursive from the above command.

This should be enough to compile Qt Creator from source. If you are interested in using other branches of the Qt Creator repository, please see the Qt Creator section at Branch Guidelines. For building Qt Creator, an out-of-source build is recommended. For simplicity, this tutorial gives instructions for a build directory namely 'qt-creator-build' that is located in parallel to the source directory 'qt-creator'but any other folder can be used.

If you have checked out Qbsit will be compiled together with the rest of the code, you do not need to do anything special. Before you start with building, make sure you are using correct version of Qt.

This can be done with the following command:. If the output points to a wrong version of Qt, or returns an error, you need to show the qmake binary to your environment it may also mean that something is wrong with your Qt installation.

You need to modify your PATH environment variable to include the directory with the qmake executable, e.

Qt Static Build on Windows

Note: Your build directory must be on the same path hierarchy level as your source directory. Other configurations are not supported by qmake in all cases. If you do not heed that rule, your Qt Creator build will fail to deploy its resources to the build directory, and you cannot run Qt Creator without installing it. Compilation takes a while only a bit less than compilation of Qt libraries themselves - so be patient.

For themes, and therefore colors, to work correctly, you may have to install QT Creator see next step. Jump to: navigationsearch. Navigation menu Personal tools Sign in. Namespaces Page Discussion.

Building Qt Creator from Git

That's an easy and quick way to take a part in developing the Qt Creator tool. With appropriate path name changes they should work on OS X and Linux, but I have not tested that yet.

I decided today that I wanted to chase down a bug in the Qt Creator 2. The official build of Qt Creator is done in an environment where the Qt Library is freshly built. In that environment, all of the private headers are present in the library tree. I also wanted to build things in such a way that I could use the "stock" version of Qt Creator as my debugger, because it has all kinds of useful IDE goodness.

Hopefully, my solution will be useful to other people who want to work on Qt Creator, either to fix a bug or to develop a new or improved Qt Creator plugin.

If you want to build Qt Creator without re-building the Qt Library, the recommended procedure is as follows:. The designer component is one of them, and that one is pretty important. If you are trying to hunt down a problem, you probably want to be using a build that is as close to the "real thing" as you can.

So my question was: what was the least change I could make to the build environment provided in the SDK that would let me do a complete build of Qt Creator? Note that these changes are pretty easy to undo. The "official" SDK tree doesn't have source code or private header files down in the Qt Version subdirectories, so they are easy to find and delete by hand. The private header files that you copied simply turn around and include things from the src tree. If you include a private header by mistake, moving the src tree will cause a compile failure.

This is a nice way to do things, since it's easy to restore. Caution: Removing the Desktop Qt component the one you just modified using the package manager will not remove the extra files. In fact, if you remove and re-install the component, they will still be present! Hopefully this sort of thing will become unnecessary when the anticipated modularity improvements to Qt Library are implemented.

I selected the MinGW build environment. I have not tested the build under Visual Studio. Once the project has loaded, you will need to make the following changes:. Now re-run qmake and re-build the QtCreator project. Depending on the power of your machine, the build make take as much as an hour.

Hint: If you plan to debug the resulting version of Qt Creator, you may find it helpful to disable Restore last session on startup in the Qt Creator session manager. If you do not disable this, the inferior version of Qt Creator the one you just built will happily load up the same Qt Creator project that you have loaded in the superior version of Qt Creator. This is amusing the first time, but both copies of Qt Creator will be attempting to update their "current session" state at the same time, which probably isn't a good thing.

If you like, you can create separate sessions named something like Superior Creator and Inferior Creator to help keep things organized. I'm off to go debug the Mercurial plugin. In the meantime, I hope this "How To" will be useful to somebody.

When you have everything installed.Your browser does not seem to support JavaScript. As a result, your viewing experience will be diminished, and you may not be able to execute some actions. Please download a browser that supports JavaScript, or enable it if it's disabled i. Linux is my development platform, but I need to package my application for Windows, too. I need to build Qt from source with -static flag.

I followed many tutorials and documents, tried VS, msys2, mingw, options A and B, But, each one failed somewhere. Has anybody recently built Qt 5. If so, which installation instructions should I follow? Happy to start from scratch, slight preference with linux-like tools rather than VSbut would accept anything. Pretty desperate here. If you feel more comfortable on Linux, why don't you cross compile for Windows? I don't know which distro you have, but there should be a package for mingw-w64, so you can build and deploy from Linux.

In theory, after installing the cross compiler, you should just run. Hi Leonardo - I tried cross-compiling the application, but that failed too due to some Windows specific optimisation requests. As you said, in theory Furthermore, the project is very Windows-centric and it does make sense to create a deployment environment on a Windows box.

Hi janeb. I followed many tutorials and documents I lost track of all my attempts. Did you fully clean your source tree between each attempt? Stale files will mess up your build. Note: Commands like make clean don't work. If using MinGW, replace make with mingwmake.

If using MSVC, replace make with nmake. AFAIK, all you need to do for a static build is add -static to the configure. Does that work? If not, post your first few error messages. Hi JKSH - thanks for your comments.

There were many attempts and I tried to make each one of them from a clean branch of source code. I haven't tried building from Git yet. All attempts failed at some point, so I asked which set of instructions I should follow in order to build Qt5 from source. Anyway, yesterday I cleaned the machine completely and started from scratch. This is what I've done so far:. This is not needed unless you want to build Qt WebKit, which is now deprecated. But if you want Qt WebKit, you'll need several other dependencies.

Windows SDK 7. What is your graphics card?You can download the Qt 5 installers and sources from the Downloads page. For more information, visit the Getting Started with Qt page. This page lists the relevant information for installing Qt by building the Qt sources.

The installation procedure is different on each Qt platform. This page collects the relevant information for the supported platforms. Building Qt revolves around using configure to configure Qt for a particular platform with a particular set of Qt features or modules. For more information, visit the following page:.

The top-level qt5 Git repository contains a set of build instructions in the form of provisioning scriptsused by Qt's continuous integration CI system to build and test the supported Reference Configurations.

These scripts are useful for anyone building Qt from source, as they provide information on the tools and components that are required for each configuration. Documentation contributions included herein are the copyrights of their respective owners.
