Compiler Options

When compiling the application, the following compiler options are required:

Option	Explanation
/c	Compile only, without linking. Linking is done as a separate phase to include the required Microsoft® SNA Server libraries.
/D NOTRC	The NOTRC macro specifies that internal tracing should not be compiled into the application. See Diagnostics for more information on the use of internal tracing. The /D NOTRC option should be used for building a final system (internal tracing should not be included because it will degrade performance and occupancy). For a development system, you may want to compile with internal tracing; if so, remove the /D NOTRC option.
/D OS2_SUPPORT, /D MSWIN_SUPPORT, /D DOS_SUPPORT, /D WIN32_SUPPORT	These macros are used in the header files FMI.H and TRACE.H, to support variants of the client interface for the operating systems OS/2, Microsoft® Windows® version 3.x, Microsoft® MS-DOS®, and Microsoft® Windows NT®/Windows 95 respectively. One of these options must be defined, depending on the operating system for which the application is intended.

Explanation

Compile only, without linking. Linking is done as a separate phase to include the required Microsoft® SNA Server libraries.

/D NOTRC

The NOTRC macro specifies that internal tracing should not be compiled into the application. See Diagnostics for more information on the use of internal tracing.

The /D NOTRC option should be used for building a final system (internal tracing should not be included because it will degrade performance and occupancy). For a development system, you may want to compile with internal tracing; if so, remove the /D NOTRC option.

/D OS2_SUPPORT,
/D MSWIN_SUPPORT,
/D DOS_SUPPORT,
/D WIN32_SUPPORT

These macros are used in the header files FMI.H and TRACE.H, to support variants of the client interface for the operating systems OS/2, Microsoft® Windows® version 3.x, Microsoft® MS-DOS®, and Microsoft® Windows NT®/Windows 95 respectively. One of these options must be defined, depending on the operating system for which the application is intended.

For Win32

/Gzs	c:	Use stdcall calling conventions on i386/i486 and Pentium processors.
	S:	Remove stack check calls.
Note::
/Gcs	c:	On MIPS, Alpha, and PowerPC processors, use Pascal calling conventions.

For Windows version 3.x, OS/2, and MS-DOS

/G2cs	2:	Use 286 instructions.
	c:	Use Pascal calling conventions.
	s:	Remove stack check calls.
/Zp	Structures must be packed.
/J	Default character type is unsigned. Not valid under Win32®.

For all operating systems

The following compiler flags are required, but any of the valid options for each flag may be used, as appropriate to your application:

/A	Compiler model
/O	Optimization
/W	Warning level
