I'm ussing QSslKey to obtain Private Key of a .key file, but when compiling, I'm getting the above error. The problem is with the QSslKey instruction.

Where is part of my code:

QFile file(PRIVATEKEY_FILE);

file.open(QIODevice::ReadOnly);
if (!file.isOpen()) {
qWarning("No se puede abrir %s", PRIVATEKEY_FILE);
return;
}

QSslKey key(&file, QSsl::Rsa, QSsl::Der, QSsl::PrivateKey, "a012345679");

if (key.isNull()) {
qWarning("No se pudo obtener la llave privada");
return;
}

Here is the compile output:

My guess is that the functions in libeay32.lib and ssleay32.lib are C-style functions and you are trying to access them as C++ functions, hence the name mangling, so force the external definitions to be extern "C" to fix it.

Thanks for your input. I have been programming C++ for quite some time and never had to combine with C code, so I really don't know where to start regarding the name mangling, besides I don't want to touch OpenSSL code, what I did, and base on your comments about the libeay32.lib and ssleay32.lib was to issolate the call to the QSslKey class and get rid of those libraries, so it would be just C++ code. But I'm getting the same results. Here is the compile output.

The had the same error. Here is my case from my blog http://kdelchev.com/articles/other/Qt_Error_collect2:_ld_returned_1_exit_status.html

This should be handled for you by adding "network" to the QT variable in your PRO file:

QT += network
