HawkEye problems with Qt

[Soudaaa]

Hi.

I've compiled the binary version of the LROSE package, which runs fine, but I'm having an issue while trying to display the CF/Radial data on HawkEye.

Everytime I try to run HawkEye, I get this error message:

This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Reinstalling the application may fix this problem.

The problems is that, I've installed Qt5 and reinstalling it didn't fix the issue, and my attempts to solve it via other means, had no success.

By the way, I'm using bash on Ubuntu on Windows 10, and I'm kinda new to linux.

Thanks

Is LD_LIBRARY_PATH set to something? Sometimes that can cause problems with where programs expect their libraries to be.

echo $LD_LIBRARY_PATH

A well compiled lrose distribution should package all its dependency libraries, including libxcb.so, under its release area, and the HawkEye executable should know where to find them. So cd to the top of your installation (one folder above where the HawkEye executable is) and then run this command:

find . -name "libxcb.so*"

If you get no result, there was a missing step in the installation.

To get an idea where HawkEye thinks the xcb library is, run this command (obviously, replace /path/to, with the appropriate location) I'm assuming you will see a "not found" next to libxcb

ldd /path/to/HawkEye | grep libxcb

Thanks for your reply

When running find . -name "libxcb.so*" i got the following result:

_./lrose_runtimelibs/libxcb.so.1

So i tried to set $LD_LIBRARY_PATH with to this path to see what happens, and the error persists.

Any idea?

[mjskier]

Did you set LD_LIBRARY_PATH to the full path to lrose_runtime_libs? or just ./lrose_runtime_libs?

Next step is to see if HawkEye knows about this path. Run ldd on it. Assuming you are in the bin folder where HawkEye is, run this and show me the output.

ldd HawkEye

Looks ok. About ldd on libxcb. Any "Not found" in the output?

ldd /usr/local/lrose/bin/./lrose_runtime_libs/libxcb.so.1

To get an idea where HawkEye thinks the xcb library is, run this command (obviously, replace /path/to, with the appropriate location) I'm assuming you will see a "not found" next to libxcb ldd /path/to/HawkEye | grep libxcb Bruno. … <#m-3000781089364102204_> On Tue, Nov 13, 2018 at 4:38 PM Soudaaa @.**> wrote: Hi. I've compiled the binary version of the LROSE package, which runs fine, but I'm having an issue while trying to display the CF/Radial data on HawkEye. Everytime I try to run HawkEye, I get this error message: This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Reinstalling the application may fix this problem. The problems is that, I've installed Qt5 and reinstalling it didn't fix the issue, and my attempts to solve it via other means, had no success. By the way, I'm using bash on Ubuntu on Windows 10, and I'm kinda new to linux. Thanks — You are receiving this because you are subscribed to this thread.

Thanks for your reply When running find . -name "libxcb.so" i got the following result: ./lrose_runtime_libs/libxcb.so.1 So i tried to set $LD_LIBRARY_PATH with to this path to see what happens, and the error persists.

if you mean ldd _/usr/local/lrose/bin/./lrose_runtime_libs/libxcb.so.1_, i got a file or directory not found

and without the asterisks, i got this:

Looks like the asterisks were added by github markdown (that's how you do bold fonts) I'm not seeing anything wrong with the library dependency.

Do you see any obvious error if you call HawkEye like this? QT_DEBUG_PLUGINS=1 /usr/local/lrose/bin/HawkEye

On my system I get an entry per plugin. The one for xcb looks like this:

QFactoryLoader::QFactoryLoader() looking at "/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so" Found metadata in lib /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so, metadata= { "IID": "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.2", "MetaData": { "Keys": [ "xcb" ] }, "className": "QXcbIntegrationPlugin", "debug": false, "version": 328450 }

Got keys from plugin meta data ("xcb")

By running this, i get the following error message:

Reinstalling the application may fix this problem. Abortado (imagem do núcleo gravada)

Weird, I don't know why it looks in /usr/local/lrose/bin/platforms.

Is there a /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms folder on your machine? If yes, try this command:

ln -s /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms /usr/local/lrose/bin/

That will create a symbolic link from where Qt looks for plugins to the place where they actually are.

What packages are installed on your machine? When I build the docker image on Ubuntu I have the following, (which bring in some more qt5 packages to resolve dependencies)

libqt5gui5 libqt5core5a qt5-default libx11-6 libfreetype6

You can run dpkg -l | grep qt5 and dpkg -l | grep libfreetype6

What's your environment? A virtual machine (which one, VirtualBox?) hosted on windows 10?

What's your environment? A virtual machine (which one, VirtualBox?) hosted on windows 10?

There is a Windows Subsystem for Linux that was launched with the Windows 10 anniversary around two years ago, where you can have the linux bash shell running on windows. It always runned fine.

For more info: https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

[mjskier]

Thanks for the link. I don't use Windows so I was not aware of this environment, we haven't tested in it. It sounds like it should work, (other people have run Qt5 apps in this env) but it might require an extra step to make it all work.

Did you install an X server for it (which one if you did)? HawkEye would need one to be able to run.

I'm using MobaXterm and I never had any problem with other packages/softwares. In the past i also used to run the environment with Xming, with no issues.

[Soudaaa]

So, is there something else i could do to fix this issue?

[mjskier]

Let's try to set the plugins path directly:

QT_PLUGIN_PATH=/usr/local/lrose/bin/lrose-blaze_runtime_libs /usr/local/lrose/bin/HawkEye

If that doesn't work, add the debug flag we used earlier to see if we get a clue (all on one line)

QT_DEBUG_PLUGINS=1 QT_PLUGIN_PATH=/usr/local/lrose/bin/lrose-blaze_runtime_libs /usr/local/lrose/bin/HawkEye

[Soudaaa]

this is what i got with the flag added:

Do you get the same thing if you set QT_PLUGIN_PATH to /usr/lib/x86_64-linux-gnu/qt5/plugins instead?

[mjskier]

What does this command give you?

nm -D /usr/local/lrose/bin/lrose-blaze_runtime_libs/libQt5Gui.so.5 | grep _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE

On my system, it finds the function: 00000000000d39d0 T _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE

[Soudaaa]

I got the following error message.

nm: '/usr/local/lrose/bin/lrose-blaze_runtime_libs/libQt5Gui.so.5': Não é esse arquivo

The translation for the sentence in the end, would be something like "it isn't the file" or "this is not the file".

[mjskier]

Sorry, I cut and pasted from a different distribution. Same command but with lroze_runtime_libs instead of lroze-blaze_runtime_libs

nm -D /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5 | grep _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE

[Soudaaa]

No problem. With the new command line, I didn't get any message whatsoever.

[mjskier]

So that's the problem. This function is supposed to be in libQt5Gui.so, but it isn't in your case.

In the remote chance that the lrose install pulled libQtGui.so in lrose_runtime_libs from somewhere else, please run the nm command on the file the build should have copied into lrose_runtime_libs

nm -D /usr/lib/x86_64-linux-gnu/libQt5Gui.so | grep _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE

On an Ubuntu 16.04 docker image, I have the same qt5 version you have:

dpkg -l | grep -i qt5gui ii libqt5gui5:amd64 5.5.1+dfsg-16ubuntu7.5 amd64 Qt 5 GUI module

nm does show that /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so contains an undefined entry for _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE, but nm shows that the function is in /usr/lib/x86_64-linux-gnu/libQt5Gui.so.

[Soudaaa]

with nm i got the following:

00000000000e0980 T _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE

[mjskier]

What's the output of these 2 commands?

ls -l /usr/lib/x86_64-linux-gnu/libQt5Gui and ls -l /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui

[mjskier]

Interesting. I would have expected /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5 and /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5.5.1 to be the same. Bug judging from the sizes, they are not.

So try this:

cd /usr/local/lrose/bin/lrose_runtime_libs mv libQt5Gui.so.5 libQt5Gui.so.5.hide ln -s /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5.5.1 libQt5Gui.so.5

We might also need to do the same thing with the other libQt5* libraries, but let's start with the obvious issues.

Then try to run HawkEye (with the debug flags)

QT_DEBUG_PLUGINS=1 QT_PLUGIN_PATH=/usr/local/lrose/bin/lrose-blaze_runtime_libs /usr/local/lrose/bin/HawkEye

[Soudaaa]

well, this is what i got:

/usr/local/lrose/bin/HawkEye: /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5: version Qt_5' not found (required by /usr/local/lrose/bin/HawkEye) /usr/local/lrose/bin/HawkEye: /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5: versionQt_5' not found (required by /usr/local/lrose/bin/lrose_runtime_libs/libQt5Widgets.so.5) /usr/local/lrose/bin/HawkEye: /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5: version `Qt_5_PRIVATE_API' not found (required by /usr/local/lrose/bin/lrose_runtime_libs/libQt5Widgets.so.5)

[mjskier]

Makes sense. All the qt5 libs need to match, so let's do the other ones:

cd /usr/local/lrose/bin/lrose_runtime_libs

mv libQt5Core.so.5 libQt5Core.so.5.hide mv libQt5Network.so.5 libQt5Network.so.5.hide mv libQt5Widgets.so.5 libQt5Widgets.so.5.hide

ln -s /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.5.1 libQt5Core.so.5 ln -s /usr/lib/x86_64-linux-gnu/libQt5Network.so.5.5.1 libQt5Network.so.5 ln -s /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5.5.1 libQt5Widgets.so.5

And try HawkEye again.

That does make me curious how lrose was compiled though. The build scripts will copy the libs it linked against into lrose_runtime_libs. So for these not to match what is in /usr/lib/x86_64-linux-gnu/ is puzzling. Was lrose compiled on a different system?

[Soudaaa]

Meh, now i got this:

/usr/local/lrose/bin/HawkEye: /usr/local/lrose/bin/lrose_runtime_libs/libQt5Gui.so.5: version `Qt_5' not found (required by /usr/local/lrose/bin/HawkEye)

I compiled LROSE only on the Windows Subsystem for Linux.

[mjskier]

Ok, let's put everything back the way it was.

cd /usr/local/lrose/bin/lrose_runtime_libs rm libQt5Core.so.5 libQt5Network.so.5 libQt5Widgets.so.5 mv libQt5Core.so.5.hide libQt5Core.so.5 mv libQt5Network.so.5.hide libQt5Network.so.5 mv libQt5Widgets.so.5.hide libQt5Widgets.so.5

What do these give you?

type qmake qmake --version

Do you have anything else on your system that might have pulled a different version of Qt5 (anaconda for example)?

[Soudaaa]

i do have miniconda on my system, and by running both commands above i got this:

qmake is /home/vitorgoede/miniconda2/bin/qmake

QMake version 2.01a Using Qt version 4.8.7 in /home/vitorgoede/miniconda2/lib

Which points to a Qt 4 version

[mjskier]

That would explain the discrepancy!

My suggestion is to rebuild lrose with /home/vitorgoede/miniconda2/bin removed from PATH We can try to play games with LD_LIBRARY_PATH and plugins location but it would be a lot simpler to just have a known configuration. (with a Qt4 qmake I'm really surprised you ended up with Qt5 components in /usr/local/lrose/bin/lrose_runtime_libs)

echo $PATH

Should give you a list of ':' separated places to look for binaries. One of the component will be /home/vitorgoede/miniconda2/bin

My suggestion is to edit your ~/.bashrc file, and comment out the line that looks like export PATH="/home/vitorgoede/miniconda2/bin:$PATH" (add a # at the start of the line)

Then in your shell, set PATH to what the echo command showed you but without /home/vitorgoede/miniconda2/bin. You do that with the 'export PATH=...' command:

export PATH=same list but without /home/vitorgoede/miniconda2/bin

And then do type qmake and verify it is /usr/bin/qmake qmake --version should be a Qt version 5

If it isn't /usr/bin/qmake, then another component you installed might have done the same thing conda did and shipped their own version of qmake. (Another potential source of problem)

From that same shell, build lrose like you did originally. Once done, you can edit ~/.bashrc again and remove the # from the export PATH line.

[Soudaaa]

Well, i did all the steps above and that xcb plugin error message just happened again.

[mjskier]

I'm going to try to find a windows 10 machine and try it myself. Probably sometime next week.

[Soudaaa]

Ok. Let me know if you have any results

[mjskier]

I got it to work this morning using the steps I use to create Docker images. So something in your setting is causing the build system to grab the wrong Qt5 libraries. It is obviously hard to debug remotely, so let me list the steps I followed. (Note that I built lrose-blaze, which is a subset of the full lrose distribution) Description here: https://nsf-lrose.github.io/

I installed Ubuntu 16.04 because I know it works. Some later versions have dropped a couple of libraries needed (libjasper and libpng12) We'll fix this eventually, but for now 16.04 is the way to go.

• Edit ~/.bashrc to specify PATH so that it doesn't include a bunch of Windows folders. Add this line anywhere (I put it toward the top)

export PATH=~/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin//bin

• grab the build/install script, and make it executable

wget "https://raw.githubusercontent.com/NCAR/lrose-core/master/build/checkout_and_build_auto.py" chmod +x checkout_and_build_auto.py

• install the required packages

sudo apt-get update sudo apt-get install -y libbz2-dev libx11-dev libpng12-dev libfftw3-dev \ libjasper-dev qtbase5-dev git \ gcc g++ gfortran libfl-dev \ automake make libtool pkg-config libexpat1-dev python

• The lrose build system expects a qmake-qt5. This isn't installed on a Ubuntu/Debian system. So make a link

ln -s /usr/lib/x86_64-linux-gnu/qt5/bin/qmake /usr/bin/qmake-qt5

• Create the /usr/local/lrose folder and change its ownership to yourself. Note that you only need to do this if you want to install in a folder that is now owned by you. /usr/local is a system folder, so unless you use sudo you can't create it, or write to it. And it is bad practice to run build scripts with sudo. Alternatively, you could specify a different folder under your $HOME as an install prefix.

sudo mkdir /usr/local/lrose sudo chown vitorgoede:vitorgoede /usr/local/lrose

• Now you can just run the build/install script.

./checkout_and_build_auto.py --debug --package lrose-blaze --prefix /usr/local/lrose --clean

This takes a while as it downloads the sources, builds in /tmp/lrose-build, and then installs. Make sure your machine doesn't go to sleep, or does an update that requires a reboot in the middle.

[Soudaaa]

It worked, thanks a lot for all your help.

[mjskier]

Good to hear. And thanks for being brave enough to try Lrose on the Linux subsystem :-)
