Packaging reported issue that python installation
without proxy didn't work - therefore enabling proxy
back was needed but with a fix to handle Py 3.10+ changes
Py 3.10+ pip 24.2 has moved to use system certifications
by default which caused issue when proxy is used
and if host didn't have one specific certification
GlobalSign Root CA - R3 for pypi.org.
Also noticed that sometimes Windows x64 images seemed to
have this missing certification, but after installing it
to Windows ARM (which was clearly missing it) - logs showed
they didn't have it - and direct check to both Win x64
Tier1 images showed that they didn't have that cert.
Not sure what steps in provisioning or proxy usage could have
affected to that, but missing certification is now added directly
to all of these new three Windows Tier 1 images:
- qtci-windows-10_22H2-x86_64-52 (via QTQAINFRA-6207)
- qtci-windows-11_23H2-x86_64-53
- qtci-windows-11_22H2-aarch64-53
Therefore --use-deprecated=legacy-certs flag is not needed
when system has correct certification available as Py 3.10+
has moved to use them by default.
Long-term improvements could still be added in future, in two ways:
1) Internal package cache (QTQAINFRA-6485 QTQAINFRA-5531), or
2) To update system certificates with Py 3.10+
But those will need more time to decide and implement.
Therefore this improved quick fix to get proxy back with Py 3.10+
was needed now and it removes previous quick fix to unset proxy.

HOW TO BUILD Qt 6
Synopsis
System requirements
- C++ compiler supporting the C++17 standard
- CMake
- Ninja
- Python 3
For more details, see also https://doc.qt.io/qt-6/build-sources.html
Linux, Mac:
cd <path>/<source_package>
./configure -prefix $PWD/qtbase
cmake --build .
Windows:
- Open a command prompt.
- Ensure that the following tools can be found in the path:
- Supported compiler (Visual Studio 2019 or later, or MinGW-builds gcc 11.2 or later)
- Python 3 ([https://www.python.org/downloads/windows/] or from Microsoft Store)
cd <path>\<source_package>
configure -prefix %CD%\qtbase
cmake --build .
More details follow.
Build!
Qt is built with CMake, and a typical
configure && cmake --build . build process is used.
If Ninja is installed, it is automatically chosen as CMake generator.
Some relevant configure options (see configure -help):
-releaseCompile and link Qt with debugging turned off.-debugCompile and link Qt with debugging turned on.
Example for a release build:
./configure -prefix $PWD/qtbase
cmake --build .
Example for a developer build: (enables more autotests, builds debug version of libraries, ...)
./configure -developer-build
cmake --build .
See output of ./configure -help for documentation on various options to
configure.
The above examples will build whatever Qt modules have been enabled by default in the build system.
It is possible to build selected repositories with their dependencies by doing
a ninja <repo-name>/all. For example, to build only qtdeclarative,
and the modules it depends on:
./configure
ninja qtdeclarative/all
This can save a lot of time if you are only interested in a subset of Qt.
Hints
The submodule repository qtrepotools contains useful scripts for
developers and release engineers. Consider adding qtrepotools/bin
to your PATH environment variable to access them.
Building Qt from git
See http://wiki.qt.io/Building_Qt_6_from_Git and README.git for more information. See http://wiki.qt.io/Qt_6 for the reference platforms.
Documentation
After configuring and compiling Qt, building the documentation is possible by running
cmake --build . --target docs
After having built the documentation, you need to install it with the following command:
cmake --build . --target install_docs
The documentation is installed in the path specified with the
configure argument -docdir.
Information about Qt's documentation is located in qtbase/doc/README
Note: Building the documentation is only tested on desktop platforms.
