QT Tips-Better manage projects (Add precompiled header files and specify where MOC files are generated) good

• Pre-compilation Accelerated compilation

Qt can also use precompiled header files like vs to speed up compiler compilation. First include the following in the. Pro file:

CONFIG + = Precompiled_header

Then define the header files that need to be precompiled:

Precompiled_header = pch.h

Where the PCH.H header file is the custom precompiled header file.

• Specify a temporary file generation directory to make the project folder cleaner

QT By default, all compiled intermediate files are generated into the debug and release folders. You can include the following in the. Pro file:

Moc_dir = Tmp/moc

Rcc_dir = TMP/RCC

Ui_dir = Tmp/ui

Objects_dir = Tmp/obj

As a result, the temporary files generated at compile time are placed in the TMP folder under the project by different types of classification.
