32 bit library to 64 bit library Qt

HashTagJF

So I am using qt 5.6 msvc2015_64bit version., the problem here is my 32 bit library doesn't work in this version. Is there anyone here who knows how to convert the 32 bit library to 64 bit library?
Your help is much appreciated.
Thank you.

first of all you should say "what doesn't work" in order to get help.

Hi,

There's no "converting" a 32bit to a 64bit library. Those are different builds. All the more on Windows you also have to ensure that you are using the same compiler for all the dependencies of your application.

So basically, if you only have access to a 32bit version of that library, you have to use a 32bit version of Qt also.

The error says "Cannot open file SerialPort.lib"
I check the library and my library is in 32 bit. My friend told me that I have to make this "SerialPort.lib" into 64 bit library. But I dunno how to do that. I'm noob when it comes to this library..

If It can't open it it's likely that it can't find it.

Then ask your friend where the sources of that library are so you can rebuilt it.

It is in the same folder where my project is.

Do you mean that the sources of SerialPort are part of your own project ?
