How to add new module ?

Hiloshi

Do you mean the content of "qt5/qtbase/include" ?
In this folder, I don't see "QTSerialPort" or anything related to serialport folder.

Is there anything wrong ?

@Hiloshi According to the log you posted it should be in /home/hiloshi/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort

Dear @jsulm , @SGaist ,

Inside the folder, there are:

hiloshi@ubuntu64:~/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort$ ls
5.8.0                QSerialPortInfo      QtSerialPortVersion
QSerialPort          qserialportinfo.h    qtserialportversion.h
qserialportglobal.h  QtSerialPort
qserialport.h        QtSerialPortDepends

Inside the 5.8.0, there are:

hiloshi@ubuntu64:~/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort/5.8.0/QtSerialPort/private$ ls
qserialportinfo_p.h  qserialport_p.h  qtudev_p.h

The above data are in the host side raspbian-jessie.img(mount as rasp-pi-rootfs folder).

Does it mean install successful ?

SGaist

Looks like it yes.

Just to be sure, you are are sure you are using the correct qmake for your project ?

Dear @SGaist ,

I think there are something wrong on the way I create project.

I import example project from:

~/rpi/qt5/qtserialport/examples/serialport/terminal

and try build and run --> It is working ~~~

But then I try to create project again, it still show:

Project ERROR: Unknown module(s) in QT: serialport

The way I create project is:

select Qt Widgets Application
input project name
Select Kit (Raspberry Pi)
Choose base class "QMainWindow"
Add serialport to the end of "QT += core gui " on pro file
Build

I compare the pro file of two project, I cannot see the mistake.

I upload the project: https://www.dropbox.com/s/fn85bcptzl2pa9k/serialport_test.rar?dl=0
Inside the rar, "terminal3" is working project, "terminal" is not working.

Any suggestion is appreciate.

Thanks,

SGaist

What do you mean by importing ?

Take a look at header of the Makefile of the two projects, the qmake line used for each is pretty different.

Hiloshi

Dear @SGaist ,

Sorry, it should be "Open Project" not import.

I may find the reason that cause this issue:

If I put my project into below folder, then build is OK:

~/rpi/qt5/qtserialport/examples/serialport/terminal/

If I put project on my original workspace, compiler will fail:

~/rpi/QT5Projects/

So I feel I may not include correct path into project.
I go through the options on qt creator, unfortunately I didn't find the place to add path.

How should I do to fix it ?

SGaist

Can you try from the command line directly ?

Hiloshi

Dear @SGaist ,

I don't familiar with command line operation, but I will check some document and try.

Do you suspect something wrong with QT Creator ?

Thanks,

Hiloshi

@SGaist said in How to add new module ?:

Just to be sure, you are are sure you are using the correct qmake for your project ?

I think you are correct, I use the wrong qmake.

My original setting about "qmake location"(in Options->Build&Run->QtVersion) is

~/rpi/qt5/qtbase/bin/

but when I build qbase, I use:

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$(which arm-linux-gnueabihf-gcc | sed 's/.\{3\}$//') -sysroot $RPIIMG -opensource -confirm-license -optimized-qmake -reduce-exports -release -no-qml-debug -make libs -make examples -prefix /usr/local/qt5pi -hostprefix $RPIQT

the -hotprefix is $RPIQT, this location is:

~/rpi/qt5pi/bin/

So I should use ~/rpi/qt5pi/bin/ .

Can you try from the command line directly ?

I found this by using command line:

$RPIQT/bin/qmake .
make

I see no error message so I goback to check qmake location and find this error.

Thank you very much.

SGaist

So you have it working now ?

Hiloshi

Dear @SGaist ,

Yes, It works fine.
