How to configure only what's necessary for a specific module.
-
If I wanted to only build say,
QtQml, but I have the entire qt (5.14) source code, what flags can I pass to the configure script to havenmakeonly produce what's necessary forQtQml?I'm also confused as to how I identify what modules produce what libraries. This was particularly confusing with
QtGui, I think it's theQtBasemodule that produces it, but am still not sure. Where can I find this information? -
It's in the dev branch.
By the way, github is only a mirror. The code resides at https://code.qt.io
@SGaist Ah ok, so to sum it all up.
- In order to identify what module will build which specific library, you should check the dev branches on https://code.qt.io/ or inspect the source code of the module
- In order to build a specific module, you have to either use the
configure/configure.batscripts and pass-skipfor every module except the ones you want. From there runningmake && make installwill build the desired modules- Additionally, you could run the
configurescript with no-skiparguments and runmake module-<name> && make module-<name>-install_subtargetsto build the desired modules.
- Additionally, you could run the
Is that correct?

You can create a module (and it's dependencies) by calling 'make module-<module-name>' (e.g. make module-qtmultimedia)
Where can I find this information?
By looking into the sources.

Hi,
In the dev branch you have the information in the dependencies.yaml file. This one is for the QtDeclarative module.
You have the --skip option to remove modules from the build list.
Otherwise, you can start with only qtbase and then manually build the modules you need.

@Christian-Ehrlicher But
QtQmlandQtGuiaren't modules. Is there no way to figure out what will produce those libraries other than digging through source code?Also tagging @SGaist
-
qtbase provides the essential modules like QtCore, QtGui etc.
Most of the other modules provide the modules matching their name with a couple of exceptions like qtdeclarative which provides QtQML.

@SGaist Interesting, I'm not seeing any
dependencies.yamlfiles in any of the modules in https://github.com/qt/qt5 Is there something that generates those? -

The information is more clearly available now with the dev branch (which is Qt 6 development).
A third option is to build qtbase first and then the other modules.
