Great project - a UI for configuring the display via ddcutil - all I ever wanted :-)

I have tried to build from the sources with Qt Creator 3.01 on Ubuntu 14.04 64 bit.

It would be great to add basic "how to build" instructions to the readme file,
esp. the dev and build environment you are using.

PS: For other readers who want to compile:

What I did so far to compile the code (more or less successfully) with

  • on Ubuntu 14.04
  • Qt version 5.2.1
  • and QtCreator 3.01
  1. Preconditions

    • clone and build ddcutil from github
      if you get the cmake error "No package 'ddcutil' found" you have forgotten this step (incl. the final sudo make install so that the C header files get installed)
  2. Edited the CMakeLists.txt file

    • Relaxed the required cmake version in first line:
      cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
    • Added a line to get rid of the "nullptr not declared in scope" error:
      set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
  3. Started Qt Creator and opened the CMakeList.txt as new project via Ctrl + O

  4. In the "Edit" view:

    • right click on the project root folder ("ddcui [master]")
    • select "Run CMake"
  5. Fixed all compile errors due to the older Qt version 5.2.1 of Ubuntu 14.04, mainly the error:

    'asprintf' is not a member of 'QString'

    by using arg instead of asprintf, e. g.
    setObjectName(QString::asprintf("FeatureWidget-0x%02x", _feature_code));
    becomes
    setObjectName(QString("FeatureWidget-0x%02x").arg(_feature_code));

  6. Specifying the run target in "Projects > Run > Run Configuration > Add > Custom executable"

    • enter ddcui as Executable

Update to build using Ubuntu 18.04 and Qt5 (for early users of ddcui ;-):

CMake will show some errors if there are missing Qt5 packages:

  1. Could not find package Configuration file provided by "Qt5Help"

    You can find the missing Ubuntu package via apt-file search Qt5Help:

    sudo apt-get install qttools5-dev

If executing ddcui fails with this error message

./ddcui
./ddcui: error while loading shared libraries: libddcutil.so.0: cannot open shared object file:
 No such file or directory

you have to update the dynamic linker run-time bindings (because you have built and installed libddcutil.so.0.0.0 into /lib/usr/lib manually as described in the preconditions of my first post above):

# optionally try this if ldconfig does not help and retry ldconfig:
# LD_LIBRARY_PATH=/usr/local/lib
sudo /sbin/ldconfig -v

Then clean and rebuild via QtCreator. ddcui can be run now:

Great work, Sanford!

I followed the build instructions but qt-qreator spits out some error message about /usr/bin/ld: cannot find -lddcutil. I installed the prebuilt binaries and development files through the ubuntu bionic ppa.

I'm sorry can you attach the `CMakeLists.txt file because the formatting is completely destroyed when copy and pasted.

Looks like the email attachment was converted to inline text by github. Here it is linked to using the github GUI.
