I tried to run a simple program that is written with Qt and uses QSslSocket.
I’m running this program on a Ubuntu 12.04 machine with OpenSSL installed.
But I got the following errors:
QSslSocket: cannot call unresolved function SSLv3_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error
How can I fix these errors?
Install the latest openSSL version.
yum install openssl,yum install libssl-dev..And add QT += network in your .pro file
