Protocol https unknown with QQNetworkAccessManager

[Snyfir]

When i try to send a post request with Qt5.5 in debian (raspbian) machine.
The error "Protocol https unknown" is displayed.

To solve this problem i try to :

• install libssl-dev
• install openssl
• copy libcrypto.so and libssl.so to /usr/lib

but he problem persist.

Do you have some idea ?

@Snyfir Why don't you simply install OpenSSL package from Debian?

[Snyfir]

@jsulm
That's what i do with "sudo apt-get install openssl", but it doesn't change anything.

[jsulm]

@Snyfir I was wondering why you copy the libs to /usr/lib?

[Snyfir]

@jsulm i see that here : http://codeblog.vurdalakov.net/2009/11/solution-qsslsocket-cannot-call.html

@Snyfir
Also you need in your project:

• libeay32.dll
• libssl32.dll
• ssleay32.dll

Hi,

What version of Raspbian are you using ? Did you check what version of OpenSSL you did install ?

[Snyfir]

@SGaist Linux pibox 4.1.19+ #858 Tue Mar 15 15:52:03 GMT 20
16 armv6l GNU/Linux

pi@pibox ~ $ openssl version
OpenSSL 1.0.1t 3 May 2016

In the config.summary of Qtbase i have:
Networking:
getaddrinfo .......... yes
getifaddrs ........... yes
IPv6 ifname .......... yes
libproxy.............. no
OpenSSL .............. no

can it be the problem or it is at yes if openssl is embeded in the executable ?

[SGaist]

You are missing the OpenSSL development package for your target in order for Qt to detect it and build the corresponding code.

when you configure qt there is an ssl option (which is off by default i think ).
+i would install newest openssl from source ~100MB, but its worth it !
