Error on ./configure script in qt-everywhere-opensource-src-5.9.6

[Hi_Be]

I am not aware of and it was not my intention. Can I check this or is it posible,
to take out of compilation?

Thank you and best regards.

The most simple is: do you need all of Qt's module right now ? If not, then only build the one you are going to use. It's going to take less time and disk space.

[Hi_Be]

No, you are right, i did not Need all modules. But there are 2 Problems.
First, if i want to skip a module, where i got the right name as skip-parameter,
because the module-names on the QT-Webseite delivers an error. For example for the
module "Qt SQL" -skip qt sql or -skip qt_sql or -skip sql doesn't work.

Second, is it possible to add later the module again, if nessecary?

https://doc.qt.io/qt-5/configure-options.html#excluding-qt-modules and
https://doc.qt.io/qt-5/sql-driver.html#building-the-drivers
You should see all options with running

configure -help

Second, is it possible to add later the module again, if nessecary?

Yes

[Hi_Be]

Sorry, may be a missunderstandig of mine, but

in https://doc.qt.io/qt-5/configure-options.html#excluding-qt-modules
is discripted:
Excluding Qt Modules¶

Configure's -skip option allows top-level source directories to be excluded from the Qt build. Note that many directories contain multiple Qt modules. For example, to exclude Qt NFC and Qt Bluetooth from the Qt build, provide -skip qtconnectivity as the argument to configure.

./configure -skip qtconnectivity

and when i look under QT-Modules (https://doc.qt.io/qt-5/qtmodules.html) i see:

The following table lists the Qt essentials:

Module

Description

Qt Core Core non-graphical classes used by other modules.
Qt GUI Base classes for graphical user interface (GUI) components. Includes OpenGL.
Qt Multimedia Classes for audio, video, radio and camera functionality.
Qt Multimedia Widgets Widget-based classes for implementing multimedia functionality.
Qt Network Classes to make network programming easier and more portable.
Qt QML Classes for QML and JavaScript languages.
Qt Quick A declarative framework for building highly dynamic applications with custom user interfaces.
Qt Quick Controls 2 Provides lightweight QML types for creating performant user interfaces for desktop, embedded, and mobile devices. These types employ a simple styling architecture and are very efficient.
Qt Quick Dialogs Types for creating and interacting with system dialogs from a Qt Quick application.
Qt Quick Layouts Layouts are items that are used to arrange Qt Quick 2 based items in the user interface.
Qt Quick Test A unit test framework for QML applications, where the test cases are written as JavaScript functions.
Qt SQL Classes for database integration using SQL.
...

Can you give me a example, how the Modul QT SQL could be excluded and where
i found the argument for skip?
May be, i understand this better.
Thank you.

@Hi_Be

You can check out what the proper options is by

./configure -help

Under windows is says:

Database options:

  -sql-<driver> ........ Enable SQL <driver> plugin. Supported drivers:
                         db2 ibase mysql oci odbc psql sqlite2 sqlite tds
                         [all auto]
  -sqlite .............. Select used sqlite3 [system/qt]

I would use the prefix "-no" which would be "-no-sql-mysql" according to this help text.

[SGaist]

To shorten things, start by only building qtbase, then you can continue with the other modules.

[Hi_Be]

Ok, now the building of qt works!

But to get the correct Parameters/arguments for adding or removing
modules likes a little as a quesswork.

For example in the documentation was the example

"./configure -skip qtconnectivity"

where "qtconnectivity" belongs to the modules "Qt NFC" and "Qt Bluetooth" (as descriped in the doc by the skip example)

But where could i find, that "qtconnectivity" was the right argument to
remove connections?

Neither the terminal Output of "./configure -help" nor the terminal
Output of the configure script, wenn running:

(an so on) contains the term "qtconnectivity".

Is there no complete list of all arguments of skip and
the belonging modules and a list of arguments off
modules which ar by -no-..... excluded?
For example:

• skip
  Connections (Bluetooth, NFC,..) - "qtconnectivity"
  Speech - "qtspeech"
  Developement Tools - "devtools"

Thank you and best regards

[SGaist]

IIRC, the skip argument matches the name of the modules you can find as sub-folders in the Qt 5 root folder.

[Hi_Be]

Thank you very much. This answer is very helpfully for me.
