Qt Creator native build error

ObiWan

Hi everybody,

I've successfully natively built Qt 5.5.1 on Pi 2.
Now I get an error when I try compile Qt Creator 3.6.
The problem is in plugins/designer:

Include and lib paths seem to be correct.
Does anybody have any idea?

Hi,

Where did you get the sources ?

ObiWan

Hi SGaist,

from http://download.qt.io/official_releases/qtcreator/3.6/3.6.0/qt-creator-opensource-src-3.6.0.tar.gz.

QDesignerComponents are afaik in Qt5Designer.
And libQt5Designer.so is in /home/pi/opt/qt551/qttools/lib.
The /usr/bin/g++ argumets seem to be correct.

SGaist

Silly question but did you use the qmake from /home/pi/opt/qt551/bin to setup the build of Qt Creator ?

ObiWan

After "sudo make install" of Qt, I added the following to my .bashrc:


LD_LIBRARY_PATH=/usr/local/qt5/lib
PATH=/usr/local/qt5/bin:$PATH

So qmake comes from /usr/local/qt5/bin.
Is that wrong?

SGaist

It depends, is it were you installed your custom Qt ? Because in your second message, you are talking about /home/pi/opt/qt551/

ObiWan

I followed the instructions on
https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
to build Qt.
I've configured it with

-prefix /usr/local/qt5

/home/pi/opt/qt551/ is the source dir.

SGaist

And is libQt5Designer.so only in the build dir ?

ObiWan

I solved the problem.
I've built qttools. But it was not enough.
I had to build qttools/src/designer/src/components.
This generates the library Qt5DesignerComponents.so.
That's it.

@SGaist: Thank you for your patience.

SGaist

Strange… But nice you found out !

Thanks for sharing !
