test qt components #5922

AndreyMlashkin · 2021-06-16T11:35:22Z

Specify library name and version: qt/5.15.2

I think, I am not an only one who would like to have a working example, demonstrating how to include different Qt modules in CMakeLists or *.pro file. test_package/ is a perfect place for it.

This is also a good place to share with all of us why you are submitting this PR (specially if it is a new addition to ConanCenter): is it a dependency of other libraries you want to package? Are you the author of the library? Thanks!

I've read the guidelines for contributing.
I've followed the PEP8 style guides for Python code in the recipes.
I've used the latest Conan client version.
I've tried at least one configuration locally with the
conan-center hook activated.

AndreyMlashkin · 2021-06-16T11:36:20Z

The test does not work for me:

[100%] Built target test_package
qt/5.15.2 (test package): Running test()
qt/5.15.2 (test package): Testing qmake
Resource content: "Hello World From Resource\n"

qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Does anyone have the same problem?

AndreyMlashkin · 2021-06-16T11:56:18Z

There is exactly the same problem in CI as I have locally

ruilvo · 2021-06-16T16:19:25Z

That probably means lack of deployment. Does this build Qt as a shared library? You can't use a Qt application before running [win/linux/mac]deployqt on it (that basically copies dlls over and creates files). It works magically on Qt Creator because it adds the Qt libs to path when you click the play button.

Now with the PR of proper Qt5 components, if you want to know how to use it, you can read the official documentation...

ericLemanissier · 2021-06-16T16:40:34Z

Do you have the problem only when using qt as a static library (which is the default)? Can you please try to use Q_IMPORT_PLUGIN ?

EDIT: the error you have is different from the one reported by the bot. In you case the executable built by qmake is able to run properly, but the executable built by cmake fails to find the xcb plugin. The bot fails to run the executable built by qmake because qt.qpa.xcb: could not connect to display, which is most probably because it runs in a headless environment.

ruilvo · 2021-06-16T16:49:37Z

Yeah, as @ericLemanissier said, this seems to be an issue with headless environments, and definitely lack of "deployment". Qt Applications aren't trivial to run.

AndreyMlashkin · 2021-06-17T07:51:07Z

I have removed a gui part, so an example should be able to run on a headless system.

ruilvo · 2021-06-17T07:51:53Z

We'll find out in a couple hours after this really have library rebuilds in the CI :)

AndreyMlashkin · 2021-06-17T07:53:12Z

I have tried to run macdeployqt with the old bincrafters recipe out of conanfile, but it didn't work on some reason for me.
If you have a working example of using it with conan installation, please share it.
Almost every user of this recipe will need it I think.

ruilvo · 2021-06-17T07:54:34Z

If you read the commit log, there was a patch explicitly for macdeploy Qt. I don't have a mac, sorry, so I can't give input.

For all interested, this code allows to create a runnable qt executable with all plugins for gui.
The only problem is that it fails on Linux because of symlinks, but still imports all needed files.

def imports(self):
   self.copy("*.dll",           dst="bin", src="bin"    , keep_path=True)
   self.copy("*.dll",           dst="bin", src="plugins", keep_path=True)
   
   self.copy("*.dylib",         dst="bin", src="lib"    , keep_path=True)
   self.copy("*.dylib",         dst="bin", src="plugins", keep_path=True)
   
   self.copy("*.so",            dst="bin", src="lib"    , keep_path=True)
   self.copy("*.so",            dst="bin", src="plugins", keep_path=True)

I have reported this issue a while ago

ruilvo · 2021-06-17T13:01:33Z

Wouldn't run [win|mac|linux]deployqt be must better in this scenario?
This is an example of the code I've used before in Windows + CMake:

  # On Windows, run windeployqt after building
  if(WIN32)
    # Run winddeployqt if it can be found
    find_program(
      WINDEPLOYQT_EXECUTABLE
      NAMES windeployqt
      HINTS ${QTDIR} ENV QTDIR
      PATH_SUFFIXES bin)
    add_custom_command(
      TARGET qt5_example
      POST_BUILD
      COMMAND ${WINDEPLOYQT_EXECUTABLE} $<TARGET_FILE:qt5_example>)
  endif()

It fails because you copy the symlinks e.g. mylibrary.so which is a symlink to mylibrary.so.5.15.2 which does not get copied by the above commands, thus you end up with a broken symlink.

AndreyMlashkin · 2021-06-23T07:45:49Z

This code worked with bincrafters recipe:

   self.copy("*.so.*.*.*", dst="bin", src="lib", keep_path=True)
   self.copy("*.so", dst="bin", src="plugins", keep_path=True)
