How to compile and run the QT part on Linux?

[matmis]

I don't know much about qt, but when I run the following:

mkdir build
cd build
qmake ../app/rtknavi_qt/rtknavi_qt.pro
make

I got the error:

../app/appcmn_qt/serioptdlg.cpp:13:50: fatal error: QtExtSerialPort/qextserialenumerator.h: No such file or directory
 #include <QtExtSerialPort/qextserialenumerator.h>
compilation terminated.
Makefile:231: recipe for target 'qextserialenumerator.o' failed
make: *** [qextserialenumerator.o] Error 1

Any suggestions?

Two quick questions. First are you using the right repository, or do you want cartoocm/RTKLIB-QT for this? Second, that error normally occurs when you are using Qt rev 4.x and fail to include the 3rd party serial stuff (it is now built into rev 5.x). [I do not know what version JensReimann used] You are better off going to Qt 5.x (currently at 5.9.1) if you can. Finally, as Qt is more of less a GUI development environment, many folks (most?) click on the *.pro file, pick the build tool chain you want (called kits now), and go on - rather than a command line.

Thank you for you answer!

I think that I'm in the right repository because I use U-blox receivers.
I installed qt5-default and did the same thing.
Now when I run
qmake ../app/rtknavi_qt/rtknavi_qt.pro
the error is:

Info: creating stash file /tmp/RTKLIB/build/.qmake.stash
Project ERROR: Unknown module(s) in QT: serialport

libqt5serialport5 is installed. (if that's useful to know)
libqt5serialport5/zesty,now 5.7.1~20161021-2build1~1 amd64 [installed,automatic]

UPDATE
I installed libqt5serialport5-dev and I could generate the "Makefile" with qmake
but when I run make
I got the following error:

make: *** No rule to make target '../../src/libRTKLib.a', needed by 'rtknavi_qt'. Stop.

I came across the same problem, so have you solved this?

Workaround

ur need to compile the static lib libRTKLib.a:

cd <PATH_TO_RTKLIB_ROOT_DIR>
qmake RTKLib.pro
make

The build process will stopped with the same error:

ar cqs libRTKLib.a rtkcmn.o convkml.o convrnx.o convgpx.o datum.o download.o ephemeris.o geoid.o gis.o ionex.o lambda.o options.o pntpos.o postpos.o ppp.o ppp_ar.o ppp_corr.o preceph.o qzslex.o rcvraw.o rinex.o rtcm.o rtcm2.o rtcm3.o rtcm3e.o rtkpos.o rtksvr.o sbas.o solution.o stream.o streamsvr.o tides.o tle.o binex.o crescent.o gw10.o javad.o novatel.o nvs.o rcvlex.o rt17.o septentrio.o skytraq.o ss2.o ublox.o tersus.o comnav.o swiftnav.o cmr.o

cd app/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/yves/Apps/RTKLIB/app/app.pro ) && make -f Makefile

make[1]: *** Keine Regel vorhanden, um das Ziel „../../src/libRTKLib.a“,

Befor the error comes, it has create the libRTKLib.a and u can find it in the src dir:

$: find . -iname '*RTKLib.a*'
./src/libRTKLib.a

The build process stopped while building the app.pro in the app dir and try to link (?) the libRTKLib.a in ../../libRTKLib.a what is wrong (there is in ../src/).
U can go into the rtknavi_qt dir and build it because there is a .pro file too:

cd app/rtknavi_qt
qmake rtknavi_qt.pro
make

Sry, i dont use QMake or QTCreator and dont know the hole build processes. but it works for me.

Thanks for the solution

qmake *.pro
make

Next error...

rtknavi_qt compilation fails in mondlg.cpp because of incompatible call for function code2obs() defined in rtklib.h :

mondlg.cpp:1864:38: error: too few arguments to function ‘char* code2obs(int, unsigned char, int*)’
In file included from mondlg.cpp:7:0:
../../src/rtklib.h:1453:14: note: declared here
 EXPORT char *code2obs(int sys, unsigned char code, int *freq);
              ^~~~~~~~
Makefile:884: recipe for target 'mondlg.o' failed

[Cyrille37]

As a hack to make rtknavi_qt compile, I modified code2base calls with add 0 as first missing parameter.

mondlg.cpp: line 1007:
code=code2obs(0,obs[i].code[k],NULL);
mondlg.cpp: line 1864:
char *code=code2obs(0, i-17,NULL);

Next error:
rtknavi_qt compilation fails because missing libgd

solution (easy):

sudo apt-get install libgd-dev

[sonicpp]

As the main RTKLib.pro has been deleted, one must compile library and apps this way:

git clone https://github.com/rtklibexplorer/RTKLIB.git
cd RTKLIB/

pushd .
cd src
qmake && make
popd

cd app/qtapp
qmake && make

Hi, I'm getting an error trying to build the RTKLIB-demo5 qt apps on Ubuntu 18.04 LTS,

$ qmake && make

          ^~~~~~~~~~~~~~~~~

the QSerialPortInfo header is installed at /usr/include/x86_64-linux-gnu/qt5/QtSerialPort/QSerialPortInfo by the libqt5serialport5-dev package. Qt5 version 5.9.5.

any ideas?

thanks,
Hamish

[HamishB]

ah, the rtk*_qt apps' Makefiles are all written including qt4, but the source code uses qt5 functions. The system's qmake is using Qt4 as linked by qtchooser?

[HamishB]

Ok, got it built, I needed to install the qt5-default package as per
https://rtklibexplorer.wordpress.com/2020/12/18/building-rtklib-code-in-linux/

[rtklibexplorer]

Qt apps are no longer supported in the 2.4.3 and demo5 versions of RTKLIB
