Can please someone explain in detail how to build a single qt module. I tried to understand the build sources documentation, but there is no info on how to build just a single module, let alone what to do with it after. I would like to do some modification on the qtmultimedia module, build it with the changes and use that module in my existing QT installation. I need only the IOS part.
Use the qmake executable from the Qt build you want to build with to create a Makefile. Then run make.
<path_to_qt_build>/bin/qmake <path_to_module>
make [or nmake or jom for windows]
