SAS/C Cross-Platform Compiler and C++ Development System User's Guide, Release 6.50


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,

  1. Select the Tools menu from the Microsoft Developer Studio toolbar.

  2. Select Compiler Options.

  3. Select SASC/C++ Cross-Platform Compiler.

  4. 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 radio button for the SAS/C and C++ compiler on the Compiler Options menu is the default selection.

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++:

  1. Select the Build menu.

  2. Select Set Active Configuration .

  3. Select the ftoc-Win32 Release project configuration.

  4. Select the Project menu.

  5. Select the Settings option.

  6. Select the general tab.

  7. Delete both the Intermediate files and Output files in the Output directories group box.

  8. Select the C/C++ tab.

  9. Remove all the Microsoft Visual C++ compiler options except for the /ML .

The SAS/C C and C++ compiler ignores the /ML option. 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
/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:"ftoc.pdb" , and /machine:IX86 . The sascc370 driver ignores these three options. 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:"ftoc.pdb" /machine:IX86 /out:"ftoc" -v .

For each source file in the Settings For text box in the Project Settings dialog box, you can set options at the source file level.

  1. Select the C/C++ tab and General from the Category drop-down menu, and enter any preprocessor definitions.
  2. Select Preprocessor from the Category drop-down menu, and enter any additional include directories.
  3. In the Undefined symbols text box, enter any sascc370 options for the compiler that are to be allocted to the selected source file. These driver options are not defined by the Microsoft IDE, and are only applicable to sascc370. A /U will prefix any options entered into this area when viewed in the Source File Options text box. The sascc370 driver ignores the /U, and passes any associated options to the appropriate phases of compilation.
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 :

Example output window contents
