Compiling Simple DAB

[andimik]

I tried to compile under Ubuntu with Qt-creator, but after 35 seconds it stops compiling:

usr/bin/ld: **/tmp/ccM3phWs.ltrans5.ltrans.o**: undefined reference to symbol 'dlclose@@GLIBC_2.2.5'

or on console with make

there are no files in /tmp/ starting with cc*.*

If I comment out the spectrum,

#CONFIG += spectrum

the error is

simple-dab.cpp:119: Fehler: ‘spectrumHandler’ was not declared in this scope
  spectrumHandler = NULL;

I am not sure what happens here. Did you install the dab library? 2017-11-08 21:40 GMT+01:00 andimik <notifications@github.com>:

I see. No, just dab-cmdline for wave, airspy and rtl_sdr.

Will test it in the next days.

[andimik]

I'll give up.

Have installed the library with

cd dab-cmdline/
cd library/
mkdir build
cd build/
cmake .. -DDABSTICK=ON -DRTLTCP=ON -DSPECTRUM=ON -DAIRSPY=ON
make
sudo make install

then I went to the simple-dab folder, but added QMAKE_CXXFLAGS += -std=c++11 to simple-dab.pro and then tried to build it

cd ..
cd simple-dab/
mkdir build
cd build/
qmake ..
make

It failed again with

/usr/bin/ld: linux-bin/simpleDab: hidden symbol `_ZN13deviceHandler12set_autogainEb' in /tmp/ccd8DNeV.ltrans2.ltrans.o is referenced by DSO
/usr/bin/ld: final link failed: Ungültiger Wert
collect2: error: ld returned 1 exit status
Makefile:185: die Regel für Ziel „linux-bin/simpleDab“ scheiterte
make: *** [linux-bin/simpleDab] Fehler 1

Even a sudo ldconfig does not help me.

This is Ubuntu 16.04 LTS

[JvanKatwijk]

It seems an issue with Ubuntu, on Fedora there is not a problem. Later forthcoming week I'll try to install Ubuntu in a virtual machine, then I can run some tests there best jan 2017-11-12 17:18 GMT+01:00 andimik <notifications@github.com>:

I tried to build it again.

Now it works, but the message in simpleDAB is now Sorry, no device found, although I've added this in the library:

See the sentence:

Does the library accept rawfiles or wavefiles?

[JvanKatwijk]

Hi Andreas I think there is a misunderstanding. The basic idea of the example programs is give people an idea of what can be done. They were not meant to be full working programs, just proof of concept. Given that thre is a library, and looking at the examples one should be able to create something to one's own ideas The simpledab version is no exception to this. It is a demonstration that the library can be used with a GUI generating mechanism The library itself is free from devices, the actual device should be handled by the demonstration program, as is the case in example-1 .. example-6. The python example is an exception to this, since I have no idea how to connect a device to the python layer, I created an interface layer between the python part and the library part, including the device. Now your question: since simpleDab is an example program, the Qt layer binds to the sdrplay device. If you really want to use it with e.g. dabstick or airspy I'll be happy to create - in source form - the configuration (not today, since I have to look after my 3 year old granddaughter the whole day, nice, funny and extremely tiring) best jan 2017-12-18 22:25 GMT+01:00 andimik <notifications@github.com>:

I see. I thought this is a very rudimentary version of qt-dab for laptops with less power.

[JvanKatwijk]

I added the possibility in configuring either dabstick, sdrplay or airspy in the simple-dab.pro file. If you are in need of having wavfiles or rawfiles added, let me know it is a matter of minutes (actually tens of minutes) adding these. best jan 2017-12-19 13:09 GMT+01:00 andimik <notifications@github.com>:
