While configure has many options which you can display by running configure -h , we will just use the defaults: %. Download the source code archive I find the easiest way to download Qt version is to browse to the and navigate to the appropriate directory. For more information, visit the page. Also, the Clang code model provides much better information about issues in code without going through the edit-compile-analyze cycle explicitly. My covered how to set up Qt and Qt Creator on a Windows 10 system. While the dependencies are typically all available as standard packages for your Linux distribution, it can take some time to identify and install all of the packages that are needed, especially on a clean system where you have never built Qt before. Step 2: Unpacking the Archive Unpack the archive if you have not done so already.
Do you accept the terms of either license? It made huge progress during the last releases, and at some point we need to do this switch. Debugging will of course work see previous answer, buit rebuilding your own Qt shouldn't actually be necessary. You should now be able to debug into Qt code. Select and download the appropriate installer. We will be building Qt natively to run on the desktop rather than as a cross-compiled version for developing code for an embedded target system. Type 'y' to accept this license offer.
. The configure script tells you which make utility to use. So during editing you will not be able to just jump straight into the Qt source code. Qt is now configured for building. For the per user install, the default installation will be a subdirectory called Qt in the current working directory.
Using the Qt online installer as I describe here will allow you to install the latest Qt release or one or more older releases, as well as install optional modules that may not be available as packages for your Linux distribution. By default we are building all Qt modules, including some large ones like QtWebEngine, as well as all the Qt examples and demos. The convenience symlink is very useful here, so we don't have to edit this file each time we upgrade to a new Qt version. The Qt Company offers a free of Qt Commercial. Conclusions I hope this tutorial has encouraged you to try building Qt on your Linux desktop. If you are using another Linux distribution, the build process will be similar but some of the specific commands will be different.
You will see several files there that offer the release in different archive formats. If you want to test an Alpha release of Qt, these are typically only provided as source code. You can download the Qt 5 sources from the page. The documentation provided herein is licensed under the terms of the as published by the Free Software Foundation. For more information please see the separate wiki page. 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 make confclean before running configure again. Once done, you can launch Qt Creator.
Figuring out all of the correct dependencies to build Qt is often the hardest part of the build process. This means that the code is highly optimized and will sometimes behave very strange when stepping inside Qt binaries. Other versions of Qt will follow a similar process. Assumptions and Prerequisites For this example I will assume you want to install Qt 5. That should get you to the right place, independently of whether the code was provided by some included header file or not.
Rationale Why would you want to build Qt from source? Qt binary packages for Linux don't contain debug symbols and therefore the debugger doesn't know files or line numbers where to jump to. In our case we want to select to access the official source code release for Qt 5. Qt is written in C++ and is fully object-oriented. You can pass the -j option to make specifying how many jobs to run in parallel. On a different Linux distribution you will typically need to use a different package installer program e. It supports both Qt4 and Qt5 toolkits. Then you can at least use the locator Ctrl-K to look up methods, etc.
I can assure you the deployment is quite easy since all required Qt files and libraries get copied to the build folder anyway. In this post I'll look at how to configure a Linux system for Qt desktop development. Here is an abbreviated version of the output I saw on my system: Which edition of Qt do you want to use? On Ubuntu Linux the command line tool to install packages is apt-get. So for a 4 core system we might use: % make -j4 This will take some time, anywhere from under an hour on a fast machine to many hours on a low-end computer. Let's walk through the process for doing this on a Linux desktop system showing in detail the commands used to perform all the steps. I've found this can happen when building QtWebEngine, as it has some large files that require a significant amount of memory to compile.
We didn't cover the Mac desktop platform, but it is much the same as Linux. It has been successfully tested with both 64-bit and 32-bit instruction set architectures. If not, you can download it from , and place it somewhere in your path. You can directly download the latest installer from You need to select either the 32-bit or 64-bit installer, depending on the architecture of your system. You can also refer to the following link for a complete list of requirements and possible build customization on all platforms: Hi Amin, I am trying to compile the latest version, 5.
