Problem with openSSL and Qt 6.5.0 beta 2

Francky033

Until this morning, my application was working normally on Android. But since the update from Qt 6.5.0 beta1 to beta2, internet access is not possible anymore...

I get the error message :

E linker  : library "/system/lib/libcrypto.so" ("/system/lib/libcrypto.so") needed or dlopened by "/data/app/~~Wx3e7tnLLjpOOU6Qk_lGUw==/net.winstars3.test-ZPEUq_vkP5poICf2sCM8ew==/lib/arm64/libQt6Core_arm64-v8a.so" is not accessible for the namespace: [name="classloader-namespace", ld_library_paths="", default_library_paths="/data/app/~~Wx3e7tnLLjpOOU6Qk_lGUw==/net.winstars3.test-ZPEUq_vkP5poICf2sCM8ew==/lib/arm64:/data/app/~~Wx3e7tnLLjpOOU6Qk_lGUw==/net.test-ZPEUq_vkP5poICf2sCM8ew==/base.apk!/lib/arm64-v8a", permitted_paths="/data:/mnt/expand:/data/data/net.winstars3.test"]
W qt.tlsbackend.ossl: : Failed to load libssl/libcrypto.

After reading this article on the blog (https://www.qt.io/blog/moving-to-openssl-3-in-binary-builds-starting-from-qt-6.5-beta-2) , I compiled in shared the openssl 3.0.7 library for Android, with success, but I still get the same error message.

But how to know with which version of openssl Qt 6.5.0 beta2 has been compiled ?

What can I do?

Thank you for your help!

I guess libcrypto.so is not added to your apk. You can manually check if your apk has it or not.

I have something like in my pro file for Qt5.
LIBS += $$ANDROID_SDK_ROOT/android_openssl/latest/arm64/libcrypto_1_1.so
ANDROID_EXTRA_LIBS += $$ANDROID_SDK_ROOT/android_openssl/latest/arm64/libcrypto_1_1.so

Hi JoeCFD,

I have just checked following your method and there are libraries libcrypto.so and libssl.so included in the apk file (and they are in the right format: arm64_v8a).
But, is this new Qt 6.5.0 beta2 version now incompatible with openssl 1.1 because I just tried with openssl1.1 and it doesn't work any more?

Thanks JoeCDF for the hints, but I had already followed these explanations for the previous version of my program, and everything worked correctly.
I just have the impression that there was a change with Qt 6.5.0 beta2... but what...?

The error message is not very explicit. How can I find out more about what's wrong?

JoeCFD

@Francky033 then do not use Qt 6.5.0 and try the version which works. Not the latest version is the best. I have not switched to Qt6.

Francky033

Ok. Thanks @JoeCFD !

@Francky033 I have the same issue, have you found a workaround or post a ticket on bug tracker ?

@Francky033 you should oben a bugreport - so Qt knows about problem in 6.5 Beta

Lilde

I open the bug report : https://bugreports.qt.io/browse/QTBUG-110915
@Francky033 Please feel free to add comments about your try with openssl 3

Francky033

ok @Lilde !

Francky033

It works in the end! In fact, you have to rename libcryto.so to libcrypto_3.so and libssl.so to libssl_3.so

Thanks to all !

Thank you for the suggestions, JoeCDF, but I had already followed these instructions for the previous version of my programme, and everything worked fine.
