Openshot-qt: AppImage install failure on Linux Mint 18 Cinnamon 64-bit - wrong qt lib

[Windsurfer01]

This error repeatedly occurs in the log file:
In /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqeglfs.so:
Plugin uses incompatible Qt library (5.5.1) [release]
"The plugin '/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqeglfs.so' uses incompatible Qt library. (5.5.1) [release]"

I have qt 5.5.1 installed.

[Windsurfer01]

I forgot to mention that it is OpenShot 2.1.

This is because the OpenShot AppImage does not correctly bundle its own qt5/plugins/. Qt then tries to load the plugins from the host system, which doesn't work due to version mismatch. The OpenShot AppImage needs to be fixed.

[jonoomph]

Looking into this now. Our AppImage does include the plugins correctly, at least based on my initial investigation. However, I think I need to include a qt.conf file, which tells Qt where to look for it's plugins... and basically ignore the system PATH. I'll keep you posted.

[jonoomph]

Committed a fix which adds a qt.conf file, which will hopefully help set the prefix correctly, and only search the current folder, rather than the system Qt path. I'll give it a test on Mint 18/Cinnamon/64-bit, and see what happens. =)

[Windsurfer01]

Thanks for the rapid response. I tried the new commit. Qt appears to load correctly, but there is an error report in the last line. See attached log file.
Openshot_log_1.txt

I also noticed with the earlier version that it created a menu entry in 'Other' rather than 'Sound and Video'. Should I make another error report for this?

[Windsurfer01]

The error is issue #298.

[Windsurfer01]

Sorry, I closed it in error.

[probonopd]

Looks like the plugin mismatch is solved, which is great 👍

So the error you are getting now is

g_type_check_instance_is_fundamentally_a

Which means you now have a duplicate to https://github.com/OpenShot/openshot-qt/issues/298

I answered there.

[Windsurfer01]

If the latest libraries are now included, and is contained in the AppImage, then it appears that they may need renaming within the AppImage, or that the file names are being read, rather than the internal version number. My Linux Mint 18 Synaptic shows the correct files are present as per attached screenshot.

I will try copying them with a new name, or making some symlinks and report back.

[Windsurfer01]

I followed the instructions at #298 exactly, and copied the files into /home/mike/usr/lib/. I moved the AppImage to /home/mike, deleted .openshot_qt, removed the menu entry in Other and ran AppImage again.

A dialog appeared warning about a gtk issue. 'Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.' I closed it and continued. The application would not start. I ran the AppImage again and the gtk warning did not appear. Still nothing appears to work.

I cannot reproduce the gtk dialog warning, but it at the start of the log.

Are there any folders other than .openshot_qt that I need to remove?

[probonopd]

You understand that the steps I posted in #298 must be done at AppImage creation time, not when using the AppImage? So @jonoomph would have to do this in his build process.

[Windsurfer01]

Yes. I deleted everything except AppImage. Followed your steps, and then
ran AppImage.

Sorry, but " I deleted everything except AppImage" doesn't sound like you have understood it. Let @jonoomph fix the AppImage and then retry.

[Windsurfer01]

@probonopd thanks for trying to help me.

I first tried the basic download, but have since been using OpenShot-v2.1.0-6-gdb65e4f-49-580-x86_64.AppImage (Sept. 9, 2016, 12:02 a.m.) which @jonoomph loaded after I first posted. I assumed it had a fix in it. I could not see the point of deleting it, as there was nothing later, and I assumed that it is not self modifying.

The first screen shot attachment (example file) indicates that I have the required files in /usr/lib as a symlink pointing to the real files in /usr/lib/x86_64-linux-gnu which is the Linux Mint 18 default. In /usr/lib/x86_64-linux-gnu are the all the files typically shown in the second screen shot. All the symlinks appear to point to the highlighted files as shown in the second screen shot. These are all installed by Linux Mint in a fresh install, or by AppImage. I cannot tell which.

I also have all of the libg*.so files in /home/mike/usr/lib/ which is the place that I assumed you require them.

So it is very possible that I don't understand what is required. I hope this helps you to understand what is in my system.

[probonopd]

@Windsurfer01 yes I think I understand and all I can tell you is _NOT_ to change things in your base system but wait for @jonoomph to fix the AppImage. Otherwise you might damage your base system.

[Windsurfer01]

Thanks. We certainly agree on not changing the base system. AppImage
seems to have all the dependency hell of debs.

The AppImage should be fixed now. I can successfully run it on Mint 18. Please give this a try again, and re-open this ticket if it still breaks. Please visit www.openshot.org/download, click 'Other Downloads', and install the latest daily build of OpenShot's AppImage. Thanks!

[Windsurfer01]

Thanks Jonathan,

It now installs (Sept 12th version) and opens in Linux Mint 18.
