How to compile and run the QT part on Linux?

[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);

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
make[1]: Verzeichnis „/home/yves/Apps/RTKLIB/src“ wird verlassen
cd app/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/yves/Apps/RTKLIB/app/app.pro ) && make -f Makefile 
make[1]: Verzeichnis „/home/yves/Apps/RTKLIB/app“ wird betreten
make[1]: *** Keine Regel vorhanden, um das Ziel „../../src/libRTKLib.a“, 
  benötigt von „rtknavi_qt“, zu erstellen.  Schluss.

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.

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?

[Cyrille37]

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]

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

          ^~~~~~~~~~~~~~~~~
compilation terminated.

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/

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