Describe the bug QT_6_PRIVATE_API not found

Project:

Error Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/QtJambi6.5.5_73236/lib/libQtJambi.so.6.5.5: /usr/lib64/libQt6Core.so.6.6.2: version 'Qt_6_PRIVATE_API' not found (required by /tmp/QtJambi6.5.5_73236/lib/libQtJambi.so.6.5.5) at java.base/jdk.internal.loader.NativeLibraries.load(Native Method) at java.base/jdk.internal.loader.NativeLibraries$NativeLibraryImpl.open(NativeLibraries.java:331) at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:197) at java.base/jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:139)

System (please complete the following information):

This is a typical issue when running QtJambi with system-specific Qt on Linux. Maven-published QtJambi binaries for Linux have been built with Qt from official installer (www.qt.io). Either use Qt from installer or build QtJambi from Github sources on your Linux system.

Sorry, I misinterpreted you post. In fact you are trying to run QtJambi 6.5 with Qt 6.6. Try again with QtJambi 6.6.2. If you face further linking issues consider my previous answer.

changed the version from 6.5.5 to 6.6.2

got an extra error:

What does this print?

strings /usr/lib64/libQt6Core.so.6.6.2 | grep Qt_6
akashKarmakar02 commented 8 months ago

strings /usr/lib64/libQt6Core.so.6.6.2 | grep Qt_6 Qt_6.6_PRIVATE_API Qt_6 Qt_6.0 Qt_6.1 Qt_6.2 Qt_6.3 Qt_6.4 Qt_6.5 Qt_6.6

And here are the symbols in Qt from installer: strings /opt/Qt/6.6.2/gcc_64/lib/libQt6Core.so.6.6.2 | grep Qt_6 Qt_6_PRIVATE_API Qt_6 Qt_6.0 Qt_6.1 Qt_6.2 Qt_6.3 Qt_6.4 Qt_6.5 Qt_6.6 Both compilations use different symbols and so, QtJambi binaries are incompatible.
