Qt for Linux/X11 - 从源代码构建

This page describes configuring and building Qt for Linux/X11 from sources. Note that it is typically easier to install the pre-built Qt libraries and tools via the Qt Online Installer . A lot of Linux distributions also provide Qt packages through their package manager. Build Qt from sources, however, if you want to customize Qt further or are using a distribution for which no binary Qt packages (in the right version) are available.

Distribution packagers can find further information on how to package Qt in the packaging recommendations .

Step 1: Getting the Sources

Qt sources can be installed in the Qt Online Installer. Source packages are also available as Git repositories , as archives in the Qt 帐户 (commercial users), and on download.qt.io (open-source users).

If you install the sources through the Qt Online Installer, they will be available in the Qt installation directory, for example $HOME/Qt/6.5.1/Src .

If you downloaded the single source archive, extract it to a directory of your choice:

cd ~/dev
tar xf ~/Downloads/qt-everywhere-src-6.5.1.tar.xz
					

Step 2: Install Build Requirements

Building Qt requires a build environment with tools, compilers, and development packages.

构建工具

工具 支持版本
CMake Version 3.16 and newer (3.21 and newer for -static builds).
Ninja -
Python Version 3

注意: configure always uses the Ninja generator and build tool if a ninja executable is available. Ninja is cross-platform, feature-rich, performant, and recommended on all platforms. The use of other generators might work but is not officially supported.

Compilers & Development Packages

The following compilers and configurations are supported in Qt 6.5:

分发 体系结构 编译器 注意事项
Red Hat 8.4 x86_64 GCC 10 (toolset)
Red Hat 9.0 x86_64 GCC 11
openSUSE 15.4 x86_64 GCC 9
SUSE Linux Enterprise Server 15 SP4 x86_64 GCC 10
Ubuntu 22.04 x86_64 由 Canonical 提供的 GCC,GCC 11.x

Other compilers and configurations might work but are not actively tested.

Qt also relies on the availability of various libraries and development packages, which are typically installed by the package manager of the respective resolution. See Qt for X11 要求 for the details.

Step 3: Build the Qt Libraries and Tools

运行 ./configure script in the package directory to configure your build:

cd /tmp/qt-everywhere-src-6.5.1
./configure
					

By default, Qt is configured for installation in the /usr/local/Qt-6.5.1 directory. This can be changed by using the -prefix option. See the list of configure options to tweak further.

Did configure run successfully? Then proceed with building the libraries and tools:

cmake --build . --parallel
					

After building, you need to install the libraries and tools in the appropriate place (unless you enabled a developer build ):

cmake --install .
					

Note that this might require root access.

Step 4: Using Qt

After Qt is installed, you can start building applications with it.

If you work from the command line, consider adding the Qt tools to your default PATH . This is done as follows:

.profile (if your shell is bash, ksh, zsh or sh), add the following lines:

PATH=/usr/local/Qt-6.5.1/bin:$PATH
export PATH
					

.login (if your shell is csh or tcsh), add the following line:

setenv PATH /usr/local/Qt-6.5.1/bin:$PATH
					

If you plan to use Qt from an IDE, you need to register the Qt version explicitly there. For Qt Creator, see Qt Creator: Adding Qt Versions .
