Qt Creator 4.2 not starting anymore on my Debian

Nando

Hi,

i just upgraded to Qt 5.7.1 and QtCreator 4.2 and now i get these errors:

qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks

Any ideas?

i reinstall latest openssl and libssl-dev which did not solve the problem

Greetings

Nando

@Nando
I now have a workaround: i use debian stretch 64bit.

there are different ssl and crypt libs in /usr/lib/x86_64-linux-gnu

libcrypto.so -> libcrypto.so.1.1
libssl.so -> libssl.so.1.1

i changed then links from version 1.1 to 1.0.2

libcrypto.so -> libcrypto.so.1.0.2
libssl.so -> libssl.so.1.0.2

This seems to work now ....

Greetings
Nando

@Nando Try running ldd on your qt creator binary, to see where it thinks the SSL libraries should be located. That should tell you if you have the right version or perhaps if you are just missing a symlink or something (which is the usual culprit).

Output should be something like this:

You may need to go a bit deeper and run ldd on the Qt5Network lib as well. That should tell you the problem though.

@Nando
I now have a workaround: i use debian stretch 64bit.

there are different ssl and crypt libs in /usr/lib/x86_64-linux-gnu

libcrypto.so -> libcrypto.so.1.1
libssl.so -> libssl.so.1.1

i changed then links from version 1.1 to 1.0.2

libcrypto.so -> libcrypto.so.1.0.2
libssl.so -> libssl.so.1.0.2

This seems to work now ....
