CHAPTER 3: USING THE SNAP ETHERNET I/O DRIVER TOOLKIT
Using Visual C++ with the Core C++ Code
The core C++ classes are found in the OptoENET-IO\DriverToolkit\Dev\Source\C++ directory. To
use them in a Visual C++ project, you'll need to do the following:
1. Add the appropriate files to the projects. Turn off precompiled headers for these files by
adjusting the settings in the compiler.
2. Link Windows Sockets into your project. Add the library file ws2_32.lib for WinSock 2.0 to
your project linker settings. These files should be included with your Visual C++ compiler.
Using Linux g++ with the Core C++ Code
The Red Hat 7.2 distribution of Linux for Intel and the GNU g++ compiler were used to test the
core C++ classes.
The class files are found in the OptoENET-IO\DriverToolkit\Dev\Source\C++ directory. Simply
include them in your project. Add a “-D_LINUX” command to the g++ prompt to make sure
_LINUX is defined.
