System Configuration

Table 1 shows a breakdown of all files which are included in the compilation of all components of the library, along with a description. An OSI_Threads component must be include all of these files on the respective platform if the component is to compile error-free.

Failure to find any of the necessary included files will immediately generate an error in a program built with PiThreads.
There are certain compiler options which must be issued. On the Win32 side, the run time library must be properly configured to handle multi-threaded code. This is accomplished in Microsoft Visual C++ by going to the project settings window and selecting the C/C++ pane. Then select the category code generation and changing the “Use run time library” option to Multithreaded or Debug Multithreaded. On the POSIX side, a program built with PiThreads must be compiled along with two flags, -D_REENTRANT and –lpthread.
