如何在QT上配置OpenSSL

Question

How can I make my QwebView/QNetWorkRequest work with SSL ?

QT return this errors (is clear that the error occurs because I did not configure SSL in my application):

QSslSocket: cannot resolve OPENSSL_add_all_algorithms_noconf QSslSocket: cannot resolve OPENSSL_add_all_algorithms_conf QSslSocket: cannot call unresolved function OPENSSL_add_all_algorithms_conf

I am use Qt 5.1.1 for Windows 32-bit (MinGW 4.8, OpenGL) - my window is 64bit

I'll be honest, I have no idea where to start. I searched but have not found anywhere that shows how trabalar SSL with QNetWorkRequest .

I install openSslWin32 (my Windows is 64bit, but my application is 32bit), I try this:

pro file:

LIBS += -LC:/OpenSSL-Win32/lib -lubsec
INCLUDEPATH += C:/OpenSSL-Win32/include

cpp file:

#include <openssl/aes.h>

But continues to show errors.

I know it is missing something, but do not know what exactly, forgive me I'm beginner.

Answer 1

I am install OpenSSL 32bit, is now working.

Download precompiled for Windows:

http://slproweb.com/products/Win32OpenSSL.html

Downloads:

• Win32: http://slproweb.com/download/Win32OpenSSL_Light-1_0_2j.exe
• Win64: http://slproweb.com/download/Win64OpenSSL_Light-1_0_2j.exe

After install copy DLLs (from C:\\OpenSSL-Win32 or C:\\OpenSSL-Win64 , depends on whether you will compile with Qt 32bit or Qt 64bit) for release or debug project folder:

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

Note: No need to add anything to "LIBS +="

Answer 2

You may be missing a bunch of libraries.

Go into C:/OpenSSL-Win32/lib and find out which 32 bit libraries are present and add them all to your link line,

ie if libXYZ.a is present in the directory add -lXYZ to your LIBS += statement.
