Build Qt5 with developer-build on ubuntu by the instruction, got error

I tried to build Qt5 on Ubuntu by the instruction https://wiki.qt.io/Building_Qt_5_fro...he_source_code

and pick this option in build:

Code:

---

$ ../qt5/configure -developer-build -opensource -nomake examples -nomake tests

---

all the way is without error but at

Code:

---

$ make -j4

---

...
...

Code:

---

make[5]: Entering directory '/opt/qt5/qtbase/src/plugins/bearer/networkmanager'
make[5]: *** No targets.  Stop.
make[5]: Leaving directory '/opt/qt5/qtbase/src/plugins/bearer/networkmanager'

make[5]: Nothing to be done for 'first'.

next error is

Code:

what would be the cause as every requirement suggested is fullfilled.. Thanks

What was the output of configure?

If you run the make without parallel jobs (no "-j4" option) does that make a difference?

Now got error in configure, as I move up to ver 5.15

as I'm new in Qt, this trouble is daunting me which I have no the slightest idea what's the cause.. any useful hint is appreciated

Don't do an in-source build.

So what should I do to solve it?

Read the documentation on Qt Configure Options, especially the section on Source, Build, and Install Directories. You do an out-of-source build using the -prefix option to specify where the output goes.
