Failed building QT Creator from source

[JANG SOONMYUN]

Hi,

After I built and installed QT from source, I tried to build QT Creator from source as following tutorials:
QT: https://wiki.qt.io/Building_Qt_5_from_Git
QT Creator: https://wiki.qt.io/Building_Qt_Creator_from_Git

Environment: Jatson Xavier NX, Jetpack4.5.1

I will describe my steps:

1. QT build
   $ git clone https://code.qt.io/qt/qt5.git
   $ cd qt5
   $ git checkout 5.14.0
   $ perl init-repository
   $ export LLVM_INSTALL_DIR=/usr/lib/llvm-6.0
   $ cd ..
   $ mkdir qt5-build
   $ cd qt5-build
   $ ../qt5/configure -developer-build -opensource -nomake examples -nomake tests
   $ make -j$(nproc)
   $ make install
   And add to ~/.bashrc: export PATH=/home/contrel/Downloads/qt5-build/qtbase/bin:$PATH

2. QT Creator build
   $ cd ..
   $ git clone --recursive https://code.qt.io/qt-creator/qt-creator.git
   $ sudo apt-get install llvm-10
   $ export LLVM_INSTALL_DIR=/usr/lib/llvm-10
   $ mkdir qt-creator-build
   $ cd qt-creator-build
   $ qmake ../qt-creator/qtcreator.pro
   $ make qmake_all
   $ make -j4

But it failed with the error message while building QT Creator [make -j4]:
