Build dependencies

[taisto]

After following the build instructions I get an error during compilation with qt4.8:
In file included from src/main.cpp:1:0: src/miomain.h:8:30: fatal error: QCommandLineParser: Datei oder Verzeichnis nicht gefunden #include <QCommandLineParser>
From searching online I get the impression, that QCommandLineParser was introduced with qt5.2.

Ok, again I broke the compatibility with QT4.8...
Qt5.2 is about 3 Years old. Do you think backward compatibility to QT4.x ist still needed? What distro are you on?

After retrying with QT5 compilation works fine for me. I guess all it takes is an update of the build instructions.

@MatthewGitter Do you use QT >= 5.2?

[MatthewGitter]

After I ran ------------------------------ $ sudo apt-get install qt4-qmake-dev libqt4-dev libasound2-dev libusb- 1.0-0-dev ------------------------------ to satisfy other installation dependencies, but still failed on QCommandLineParser: ------------------------------ $ qmake --version QMake version 2.01a Using Qt version 4.8.7 in /usr/lib/x86_64-linux-gnu $ pkg-config --modversion QtCore 4.8.7 ------------------------------

Then everything is ok. You still need QT5.2 or later and as you clearly stated you have only4.8.x.

[MatthewGitter]

It was already installed (as per https://github.com/dehnhardt/iconnconfig/blob/master/BUILD.md ): ------------------------------------------ $ sudo apt-get install qtbase5-dev Reading package lists... Done Building dependency tree Reading state information... Done qtbase5-dev is already the newest version (5.9.5+dfsg-0ubuntu1). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. ------------------------------------------

I noticed in the BUILD.md doc that I needed to install libclalsadrv-dev , so I did. I ran qmake -qt=5 ; make again (this time including the -qt=5). This time no problem (except a warning on a switch/case default fallthru) building, and it runs and finds my device. I suppose it what the -qt-5 switch to qmake that made the difference.

Ok, thanks for the finding. I will add that tip that in the dependencies file,
