Unable to find the platform plugin.

[SGaist]

In one of the bug report linked in the thread you got inspiration from, it's explicitly stated that you should not use --release with the pre-built binary. They are built in release mode with debug symbols.

After removing --release from the command, I could successfully deploy it with out the platform plugin error. Although, there is a strange thing happening. It is missing out the texttospeech plugin. I get this error when I run the executable from Qt creator after using the windeployqt

No text-to-speech plug-ins were found.

The same error I had shared on this post.

And that was solved using Qt 5.15, correct ?

[saitej]

@SGaist

Ya. but I had not used windeployqt in the release folder at that time. As soon as I run windeployqt, i get this error No text-to-speech plug-ins were found. and the speech part does not work

Check the corresponding plugins in your Qt installation and copy them over to your deployment folder.

@SGaist

Yes. I have already tried copying the following relevant texttospeech files from the Qt installation directory. Hope I have not missed out any? Also, is it possible that texttospeech does not work in a Qt Quick Application?

[SGaist]

It's the deployed version that currently has issues, correct ?

[saitej]

@SGaist

Yes Sir.

[SGaist]

Did you add the -texttospeech option to your windeployqt call ?

[saitej]

@SGaist said in Unable to find the platform plugin.:

-texttospeech

Ya I have tried adding -texttospeech in the windeployqt command also but no success. It still gives the same No text-to-speech plug-ins were found. error

[SGaist]

Did you do that in a clean folder ?
