Error while loading shared libraries: libQt5Bluetooth.so.5

@Yaldiz said in Error while loading shared libraries: libQt5Bluetooth.so.5:

Qt += bluetooth

This needs to be QT

LIBS += -L/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include -lbluetooth

Library in /include folder? Looks suspicious, check if it's a good path.

unix:!macx: LIBS += -L$$PWD/../../../../../opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/lib/ -lQt5Bluetooth

INCLUDEPATH += $$PWD/../../../../../opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include/QtBluetooth
DEPENDPATH += $$PWD/../../../../../opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include/QtBluetooth

I tried like this gives same error.

NOTE: Project compiling succesfully but when i try to run executable file on the target gives this error.

Add /opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/lib/ to LD_LIBRARY_PATH, then.

[Yaldiz]

I tried following rule;

LD_LIBRARY_PATH=/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/lib/:${LD_LIBRARY_PATH}

same error still exist.

Since bluetooth is a Qt component, you do not need to add it to LIBS. Just like core gui widgets, right? They are added automatically.

[Yaldiz]

Yes, i understand it but i tried theese rules ;
Qt += bluetooth and mentioned way theese gives same errors.

As mentioned, it HAS TO BE QT (both letters capital). Qt won't do! And after you change anything in .pro file, it's best to make a full rebuild - remove build dir, run qmake and make again.

Other libs (core, gui, etc.) link correctly right?

It's a long shot, but maybe check if your bluetooth lib is compiled for correct architecture:

readelf -h /opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/lib/libQt5Bluetooth.so.5.14.2

[Yaldiz]

core, gui, dbus, network linked correctly.

I can use sqlite3 with following rule.
LIBS += -L/opt/tdx-xwayland/5.6.0/sysroots/armv7at2hf-neon-tdx-linux-gnueabi/usr/include -lsqlite3

Project compiled for correct architecture(ARM).

Best Regards.

[sierdzio]

Yep, looks correct.

libQt5Bluetooth.so.5.14.2 found, but CRC does not match

Is this only about the symlink or the file is corrupt?

Anyway, I've run out of ideas, sorry :-(

[Yaldiz]

Thanks for the help and for your time :)

It does not help if the bluetooth library is in the SDK. Error clearly states that it's not found in actual device. Also very suspicious that in the SDK path you have Qt version 5.6.0 but then bluetooth library is version 5.14.2. So do you actually have Qt 5.6.0 and you've just replaced/added bluetooth library from newer Qt5 version? That would explain the readelf warning.
