Debian Stable Qt55_DIR

[kt10aan]

Hi,

After happily using the qtguis in debian testing, I am trying to compile the qt guis in Debian Stable. I have install Qt through the Qt project website and placed it in /usr/local/Qt.

I check in the top level CMakeLists.txt of qtyarp what cmake files are needed and I setup an variable Qt5_DIR in my bashrc:

/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Core:/usr/local/Qt/ 5.3.1/gcc_64/lib/cmake/Qt5Widgets:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Quick:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Qml:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Multimedia:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Xml:/usr/local/ Qt/5.3.1/gcc_64/lib/cmake/Qt5PrintSupport:/usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5Network

But I do get: CMake Error at cmake/FeatureSummary.cmake:537 (message): feature_summary() Error: REQUIRED package(s) are missing, aborting CMake run.

The same happens if I enter the above collection of paths in the Qt5_DIR in ccmake.

Are there any more Qt5* paths I should include?

Or even better, is it possible for Cmake to go through these packages automatically if the user just sets up the Qt5_DIR variable to the top level Qt5 install directory (in this case, /usr/local/Qt).

Thanks, Kostas

Qt5_DIR cannot be a collection of dirs, it should be a single directory, just the first one should work: /usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5 As an alternative, you can try to set (or append) the CMAKE_PREFIX_PATH environment variable to /usr/local/Qt/5.3.1/gcc_64

I tried /usr/local/Qt/5.3.1/gcc_64/lib/cmake/Qt5 before I tried the collection of dirs. It was not working, complaining about missing packages. The CMAKE_PREFIX_PATH solution didnt work either :(. All this on stock debian wheezy. Cmake was from the backports, 2.8.11.1, in case it matters. Also, even the env variable Qt5_DIR is set (and bashrc sourced etc etc) and i can view it with echo $Qt5_DIR, when ccmake starts, it states Qt5_DIR as not found. Shouldn't it have as a value the value of $Qt5_DIR?

I had some progress by checking the AddOns during Qt installation. Now in cmake configure I get the error

CMake Error at /usr/local/Qt/5.3/gcc_64/lib/cmake/Qt5Gui/Qt5GuiConfig.cmake:15 (message):

I had the same problem, which is also discussed here:

http://qt-project.org/forums/viewthread/44605

It seems to be a problem with the installer script in qt. I solved it on Ubuntu 13.10 by installing libegl1-mesa-dev:

apt-get install libegl1-mesa-dev

Thanks @lornat75! Installing libegl1-mesa-dev worked. Maybe the package should added in the README.md instructions.

done!
