Using the SAS/C Cross-Platform Compiler and C++ Development System

Using SAS/C C and C++ under the Microsoft Visual C++ IDE

If you prefer to use the Microsoft Developer Studio, you can use SAS/C C and C++ within the Microsoft Visual C++ Integrated Development Environment. To ensure the SAS/C and C++ compiler is invoked in the Microsoft Developer Studio,

Select the Tools menu from the Microsoft Developer Studio toolbar.
Select Compiler Options.
Select Cross-Platform SAS.
Select OK.

When you select the SAS/C and C++ compiler from the Microsoft Developer Studio Tools menu, it becomes the default compiler whenever you restart Microsoft Visual C++. The selection button for the SAS/C and C++ compiler on the Compiler Options menu will not be highlighted, but the SAS/C and C++ compiler is the default compiler. If you later change the compiler selection from the SAS/C and C++ compiler to the Microsoft compiler, the Microsoft compiler becomes the default compiler.

To compile and prelink source code using the SAS/C and C++ compiler, you first need to configure the compile and prelink options in the Win32 Release settings for your project. Although some menu differences exist between Microsoft Visual C++ Version 4.2 and Version 5.0, these operations apply to both versions. The following examples are taken from Microsoft Visual C++ 5.0, but the SAS/C C and C++ compiler is compatible with Versions 4.2 and 5.0 of Microsoft Visual C++.

Configuring Compile and Prelink Options

The following example uses a project named ftoc . Use the following procedure to configure the compile and prelink options for the ftoc project in Microsoft Visual C++:

Select the Build menu.
Select Set Active Configuration .
Select the ftoc-Win32 Release project configuration.
Select the Project menu.
Select the Settings option.
Select the C/C++ tab.
Remove all the Microsoft Visual C++ compiler options except for the following: /ML /FO"Release/" .

The SAS/C C and C++ compiler ignores the /ML and /FO"Release/" options. Also, the Microsoft Visual C++ compiler options in Recognized Microsoft Visual C++ Compiler Options are interpreted as valid SAS/C cross-platform compiler options.

Recognized Microsoft Visual C++ Compiler Options
Microsoft Option Description

/Fdfilename Renames program database file

/nologo Suppresses display of sign-on banner

/Dname[=def] Defines constants and macros

/c Compiles without linking

/Zi Generates complete debugging information

/O Executes Global Optimizer

/O1 Executes Global Optimizer

/O2 Executes Global Optimizer

/Uname Eliminates initial name definition

/Idirectory Searches a directory for include files

***Recognized Microsoft Visual C++ Compiler Options***
Microsoft Option	Description
/Fdfilename	Renames program database file
/nologo	Suppresses display of sign-on banner
/Dname[=def]	Defines constants and macros
/c	Compiles without linking
/Zi	Generates complete debugging information
/O	Executes Global Optimizer
/O1	Executes Global Optimizer
/O2	Executes Global Optimizer
/Uname	Eliminates initial name definition
/Idirectory	Searches a directory for include files

In the Project Options field, you can add any of the SAS/C C and C++ compiler options that are listed in Compiling C and C++ Programs. For example, to specify verbose commands, automatic instantiation of class templates, run-time type identification, and reentrant code generation, add the -v , -Kautoinst , -Krtti , and -Krent options for sascc370 .

Delete all the project options under the Project Settings Link tab except for /incremental:no , /pdb:"Release/ftoc.pdb" , and /machine:IX86 . The sascc370 driver ignores these three options. Specify the names of the input object modules in the Object/library modules field. Specify the name of the prelinked output file in the Output file name field. In this example, although the input object filename, ftoc.o , is located in directory D:\Program Files\DevStudio\MyProjects\temperature , the Object/library modules field does not contain the fully qualified object file pathname. Add any sascc370 driver options for prelinking, such as -v , to the Project Options field. The Project Options field should appear as ftoc.o /incremental:no /pdb:"Release/ftoc.pdb" /machine:IX86 /out:"ftoc" -v .

Compiling and Prelinking Object Code

To compile and prelink the source code, select the Build ftoc item from the Build menu. SAS/C C and C++ generate a compiled object file, ftoc.o , and a prelinked output file, ftoc . Any execution messages or error diagnostics are displayed in the Output view. For this example, when building ftoc.cxx , the output window should contain something like the output in Example output window contents:
