how to build and install qt5.12.5 plugin for raspbian-buster in raspberry 4?

[jsulm]

@stevewu Acoording to the "make install" output it was installed in lib subdirectory, not plugins.

[stevewu]

where is the subdirectory?
I check the path /usr/bin/qt5.12.5

and the build path,

and the source path,

but can not find it,,,,

the same code , I build in windows, it seems that everything is OK! I can get the /bin /lib and /plugins.... after build.

Did you check the output from "make install" you posted?
It is right there: /usr/lib/qt5.12/lib...

[stevewu]

@jsulm thank you for reply, I check the /usr/lib/qt5.12/lib, find no subdirectory.
after “make install” ,

I check the out put from “make ”, and find that ,
it only build the code in path “/home/qt5_install/qtspeech_build/src/tts”,
so i can get "libQt5TextToSpeech.so...etc" in the /lib, after "make" ,new add libs as below:

but when it enters in “/home/qt5_install/qtspeech_build/src/plugins/tts”,
put out information "nothing need to do for the first" and left, so the /plugin not be built.

lib in/usr/lib/qt5.12/ IS the subdirectory I'm talking about.

@jsulm OK, thanks, I got it,,,
but only "libQt5TextToSpeech.so..." in /usr/lib/qt5.12/lib, is OK for the plugin "text-to-speech"?
"make" does not build the path “/home/qt5_install/qtspeech_build/src/plugins/tts”, it dose not matter?

I run a test code(which can work in the win10) on the raspberry pi4, it can build success, but run error, put out "No text-to-speech plug-ins were found."

[jsulm]

@stevewu I guess you also need to build the tts plug-in from the plugins directory

[stevewu]

ok, tks, I will try it later.....

[stevewu]

@jsulm hi, I enter the /src/plugins and make,, but it still does not work.

could you please tell me how to fix it?

[stevewu]

@jsulm thank you very much , what you said is right...
I reinstall all the libs about libflite and libspeechd, and it works..

@stevewu Hi, I meet the same problem. Could you tell me how to fix it by reinstalling the libs about libflite and libspeechd? Looking forward to your reply, Thanks!

@jsulm I meet the same problem. I check the configuration of Qt TextToSpeech, and found all 'no'. Is this the problem that I don't make the right configuration? Please help me to make the right configuraiton. Thanks.

@Peter_Gao Did you install Flite, Speech Dispatcher and their dev packages?
You can always check config.log file to see what exactly is the problem.
