Trying to compile a program on mac using Qt 5.4 clang 64bit. The program includes using Opal Kelly .dylib files and header files to talk to an FPGA connected through USB. The program compiles fine on windows with windows versions of the .dylib (.dll) and the windows header file, however on mac I get the following error trying to compile:

```
:-1: error: symbol(s) not found for architecture x86_64

```

The compiler output is:

```

```

I know this kind of error can occur when there is a SLOT or function in the header file while is not being used, however I don't know how to go about finding what is causing the issue.

The Opal Kelly header file is located [here](https://docs.google.com/document/d/10VxWnuRF6Dx566hdna4QqEsQSe3w23MLJNdyUN156rk/edit?usp=sharing).

Any help would be much appreciated, let me know if you need more info!
