compile Qt from repository using linux

QT-static-prgm

Hey,

i want to compile Qt from source multiple times.

I found this tutorial: http://doc.qt.io/qt-5/linux-building.html
But i'd prefer to download from a git repo, because i want to download and compile it within a script.
Furthermore how would i clean and rebuild?? As far as i remember confclean is no more possible.

You can use the instructions above in a script... but anyway, since you ask for git repo, here is a guide especially for that use case: https://wiki.qt.io/Building_Qt_5_from_Git

If you want to build several times from the same source code, simply run configure and make in another folder. Example:

# Let's assume you have Qt source code in folder qt-src
mkdir qt-build1
cd qt-build1
./../qt-src/configure -prefix $PWD
make 
# Now rinse and repeat for your other builds
cd ..
mkdir qt-build2
cd qt-build2
./../qt-src/configure -prefix $PWD
make

If you want to keep all the build artifacts away from results (include files and libraries), you need to point -prefix to yet another directory. And you will have to run make install after compilation is done, so that the build system has a chance to copy the libs to your prefix folder.
