Qt4::lrelease: not found Error during make

[vivekruhela]

I  am trying to install Pianobooster (dowloaded from https://github.com/minyor/PianoBooster.git) in linux. The reason to wotk with this git repo is that I want to have MIDI piano keyboard to be integrated with pianobooster software. After installing all the dependencies, cmake . is working fine but make throws an error during building process as shown below:

    /bin/sh: 1: Qt4::lrelease: not found
    build/translations/CMakeFiles/translations.dir/build.make:63: recipe for target 'build/translations/pianobooster_ja.qm' failed
    make[2]: *** [build/translations/pianobooster_ja.qm] Error 127
    CMakeFiles/Makefile2:140: recipe for target 'build/translations/CMakeFiles/translations.dir/all' failed
    make[1]: *** [build/translations/CMakeFiles/translations.dir/all] Error 2
    Makefile:129: recipe for target 'all' failed
    make: *** [all] Error 2

Can anyone suggest to me how to install pianobooster in linux. Thanks.

Sorry for the delay replying.

The latest code is https://github.com/captnfab/PianoBooster/

You need to download version v0.7.2b from here:

https://github.com/captnfab/PianoBooster/releases/tag/v0.7.2b

The steps to compile PB are as follows:

1. Download the source code and unzip it.
2. In a terminal window use cd to change to the source code directory
3. Then type mkdir build followed by cd build.
3. Then in the build directory type cmake .. 
4. Then type make
5. Finally to run piano booster type ./build/pianobooster from the terminal window from the build directory.
6 if you want to install pianobooster type sudo make install

There may be some errors asking you to install stuff and you will often need the -dev version of the missing program. If you cannot solve the error your self please post the error message to this forum.

Good luck and please post how you get on.
