Using the c89 Utility in the OSS Environment

To alter an existing DEFINE, use the add_define utility and specify all DEFINE
attributes and their new values. In this situation, the add_define utility essentially
adds a new DEFINE with the same name in place of the old DEFINE.
Using the c89 Utility in the OSS Environment
The c89 utility is the OSS driver for the C and C++ compilation systems. You use the
c89 utility to run the C and C++ compiler or ld), the TNS/E native linker (eld),
Accelerator, OCA, and SQL compiler.
With D40 and later product versions, c89 utilities are available in these ways:

The native c89 utility resides in the /usr/bin directory. For information about the
native c89 utility, see the Open System Services Shell and Utilities Reference
Manual or the c89(1) reference pages.

The TNS c89 utility has been moved from the /bin directory to the
/nonnative/bin directory. The documentation for the TNS c89 utility is
available only as reference pages. To view the TNS c89 reference pages, enter:
man -M /nonnative/usr/share/man c89
Running the OSS C Compiler
Run the OSS C compiler using the c89 utility to compile the source file (or files) that
contain the embedded SQL statements. The C compiler generates an object file that
contains C object code and SQL source statements. This c89 command invokes the
C compiler to compile the pgm1 source file into the pgm1o object file:
c89 -c pgm1
NonStop SQL/MP supports Tandem floating-point format but not IEEE floating-point
format. The floating-point format for TNS/R native compilation is Tandem by default.
However, for TNS/E native compilation, the floating-point format is IEEE by default.
Follow these guidelines when compiling C programs that contain embedded SQL/MP
statements:

For TNS/R native compilation, do not specify the -WIEEE_float flag. The
floating-point format must be the default TANDEM_FLOAT.

For TNS/E native compilation, specify the -WTandem_float flag to override the
default IEEE_FLOAT:
c89 -WTandem_float pgm1
For more information, see “Compiling and Linking Floating-Point Programs” in the
C/C++ Programmer’s Guide for NonStop Systems.
The native c89 utility resides in the /bin/compilers directory. The TNS C compiler
has been moved from the /bin/compilers directory to the
/nonnative/bin/compilers directory, and the TNS C run-time library has been
moved from /usr/lib/libc.a to /nonnative/usr/libc.a.
