[Qt-interest] Distributing a QT app that needs SSL on windows

[Scott Aron Bloom]

The problem is, the ODBC driver for SQL Server uses them as well, and
fails to connect securely.  

 

Unfortunately, there is no way to specify where QtNetwork dll's should
go...  Im really stumped on this one...

 

Usually I put it in the app dir as you recommend, but it kills the SQL
server connection.

I've found placing them in the directory the app/dll is located in is
the best place for application specific versions of DLL's.

Search order on windows is usually 1. local dir, 2. dirs in path, 3.
system dir.

So long as you don't install your app on the path, you should be good to
go.

Here is my problem, I have an app that makes HTTPS connections, and
works fine on some machines..  I distrute the DLLs from the OpenSLL
distribution package, and it will work on more machines.. HOWEVER...  On
some machines, the OpenSLL libs cause a conflict with with other SLL
libs, and for instance the ODBC connection to a SQL server fails...

 

Now, on other machines, if I don't distribute the SLL libs and they are
not already on the system I get unresolved function SSLv3_client_method
which means there are no OpenSLL dlls to be found...

 

What is the best way to distribute the SSL dlls on windows?
