LabWindows/CVI Compiler

LabWindows/CVI uses the Clang 3.3 compiler, which can generate optimized code and focuses on debugging and user protection. Because the compiler is an integral part of the LabWindows/CVI environment and features a set of straightforward options, it also is easy to use.

The default language standard of the LabWindows/CVI compiler is GNU89. GNU89 is the C89 specification with GNU extensions (some C99 features) supported. For more information about the C language extensions supported in LabWindows/CVI, visit ni.com/info and enter the following Info Code: CLangExt.

To generate code optimized for speed or size, select the amount of optimization you want from the Optimization level option in the Build Options dialog box.
