failing to build Qt, Project ERROR: Building QtQml requires Python. - ubuntu
 
Hey guys,



i am currently installing openFOAM 1912 and have some trouble building Qt. I downloaded the right tarball (https://download.qt.io/archive/qt/5.9/5.9.9/single/) extracted it into the thirdparty folder and started building it using "./makeQt 5.9.9". Just as it says in the BUILD.md



After severals minutes i get the following error and the building aborts:


Code:

Info: creating cache file /home/thenew/OpenFOAM/ThirdParty-v1912/build/linux64Gcc/qt-everywhere-opensource-src-5.9.9/qtdeclarative/.qmake.cache
sh: 1: python: not found
Project ERROR: Building QtQml requires Python.

Error building: Qt-5.9.9

I am using Ubuntu 18.04 lts on a Thinkpad e495. Any idea what caused the error and how to overcome it?


Greetings and thanks in advance:

_solved_
 
it seems in ubuntu 18.04 you cant call python by "python", if you haven't installed python2.7. So i just needed to install python 2.7, did so by

Code:

sudo apt install python
. Worked just fine afterwards.
