The TNS/E native C and C++ compilers take as input a module (a translation unit) and
generate an object file or linkfile. A module is defined as a source file with all of the
headers and source files it includes, except for any source lines skipped as the result
of conditional preprocessor directives.
The eld utility is the TNS/E native linker that links PIC (Position-Independent Code)
linkfile
s to produce PIC loadfiles.
The SQL compiler processes executable files and generates code for embedded SQL
statements.
The native c89 utility controls the TNS/E native C and C++ compilation system in the
Open System Services (OSS) environment. Note that the c89 utility on H-series
systems can generate TNS/R code for linking by the ld or nld utility (not the eld
utility) when the -Wtarget=TNS/R flag is used; discussions of OSS c89 in
Section 16, Compiling and Linking TNS/R Native C and C++ Programs
therefore apply
to H-series users when that flag is specified.
For information on how to compile and link programs in the OSS environment, see the
c89(1) reference page online or in the Open System Services Shell and Utilities
Reference Manual.
For information about compiling and binding native C++ programs using the Windows
PC environment, see the online help for the HP Enterprise Tool Kit—NonStop Edition
