Compilation, linking, starting on Windows systems

When compiling and linking CPI-C applications on Windows systems, you must observe the following:

• Every CPI-C program requires the following header files for compilation:

  #include <windows.h>

  #include <upic.h>

  The header file upic.h is located in the directory upic-dir\include.

  This order of includes shown above is mandatory. It is advisable to compile the program using the option __STDC__ (ANSI).

• When compiling CPI-C programs (UPIC remote only) you must set the following compiler options: UTM_ON_WIN32

  • UTM_ON_WIN32 on 32-bit platforms

  • UTM_ON_WIN32 and UTM_ON_WIN64 on 64-bit platforms

  You can see the effect of these options in the header file upic.h. It is located in the directory upic-dir\include.

• A CPI-C program consists of a series of modules which have to be linked to form a program. The following object modules are required for linking:

  • main program of the user

  • user modules

  • For programs which want to use PCMX:
    the library upicw32.lib (32-bit) or upicw64.lib (64-bit), located in the upic-dir\sys directory.

  • For programs which want to use Socket interface:
    the library upicws32.lib (32-bit) or upicws64.lib (64-bit), located in the upic-dir\SYS directory.

• Once the runtime environment has been made available (see below), you can start a CPI-C program just like any other program in Windows systems.
