Compiler Options for Multithreaded Applications

The following table shows the compiler or compiler/linker options that must be used to build a multithreaded application. Failure to use these options will result in undefined behavior at runtime.

¹ These macros are used to detect a multithreaded compilation. You must not set them when compiling in single-thread mode. All other platforms use the flag ILS_USE_THREADS to indicate a multithreaded compilation.
