What is my problem with 6.3 ?

[Anonymous_Banned275]

I have managed to restore access to my project.
I am not sure , but it was originally NOT build using 6.3.

Now I am getting this build error.
Should I remove the 6.3 kit ?

Hi
what is mounted on /media/ `?
Could very well be access rights or something else if I read the error right.

Where is the build folder pointing at ? (in projects )

[Anonymous_Banned275]

@mrjj Good point - I need to correlate the mount point (directory
?) and the physical location - disk and partition - to check ownership etc.
At this point I do not know how.
( Not sure I should ask Linux question here ...)

ADDENDUM
I think I found it ....

but the UUID do not match

Here is MY PROBLEM , not QT

[Anonymous_Banned275]

Please forgive me to take more bandwidth with my issue . I finally found the most recent copy of the project , however , still cannot build it.

I have two error indicators

and this

I did verify I have Bluetooth dev package installed on my Linux OS. .

It has been a whale I start using Bluetooth and serial and do not recall what else has to be done to activate these missing modules.

Quite apart from the permissions issues, this error message:

Project ERROR: Unknown modules(s) in QT: bluetooth

means you probably have not installed the Qt Connectivity module in Qt 6.3. Similar for the other Project ERRORs.

@AnneRanch
Since you earlier showed a message stating that /media/q5 is a "Read-only file system" everything goes wrong because it cannot create a Makefile etc. Look at where your project is set to use its build directory for where it puts the Makefile and the .o/executable files it generates....

If you want to build starting from a Qt example, first copy the whole example directory to somewhere where you do development in your own user area --- not in the read-only mounted area --- and do all your work there.

@ChrisW67 BINGO BUT I am pleading ignorance - when I run QT maintenance tool I always get to "install / update "
So

1. what app is this "module selection in " ? (Linux not Windoze )
2. Does it have to be installed and if so how ?

@JonB I have that solved ....

[J.Hilk]

@AnneRanch

• start the maintenance tool
• login
• add or remove components
• expand Qt tree
• expand Qt6 tree
• expand Additional Libraries tree
• set a checkmark next to Qt Connectivity and any other additional Module you're using
• click next
• let it install
• finished

@JonB I have that solved ....

well you didn't say so yet

@J-Hilk
This is what I am getting... I do not want "install" ...

[J.Hilk]

@AnneRanch mmh, have seen that one only once before,
IIRC, select custom installation, and you should get the tree selection window

[Anonymous_Banned275]

@J-Hilk After ":custom " selected it still wants to "install " and complains about existing directory. I guess I will reinstall into different directory and take a coffee break...

STILL NO MODULES

[mchinand]

Expand the Qt 6.3.1 item; that's the version you were using that produced your missing module error above. Qt6 is more modular, but you can see from your screenshot that Qt 5.15.2 has separately installable modules too, Qt Charts, Qt Quick 3D, etc.

Conclusion (Linux)
When initially loading QT

1. If version 5.x it is necessary to add libraries of interest manually
2. With version 6.3 (tested with 6.3) such libraries / components / modules should be added during install
   • selected by expanding the version of interest.

{Note to myself QT terms " library / component / module" are used interchangeably ...)

PS If it is OK with the group - I would like to delete most of the pictures.
