Compilation Tools
The c89 and c99 utilities control the C compilation system in the OSS environment. There are
native versions of c89 and c99 for TNS/E systems, a native version of c89 for TNS/R systems,
and a TNS version of c89 for TNS/R systems. (A TNS version of c89 is not supported on TNS/E
systems). The native versions are the default versions. The c99 utility is supported for TNS/E targets
on TNS/E systems only.
Native c89 and native c99 provide an interface to the components of the C compilation system,
including the C and C++ language preprocessors, C and C++ compilers, linkers (nld, ld, and
eld utilities), optimizer (built into the compilers), and the SQL compilers. The noft (on TNS/R
systems) and enoft (on TNS/E systems) utilities allow you to examine various attributes of native
object files.
TNS c89 provides an interface to the components of the C compilation system, including the C
and C++ language preprocessors, C and C++ compilers, linkers (Binder), Accelerator (on TNS/R
systems), and the SQL/MP compiler.
Table 3 shows some sample c89 commands. For each sample command, the table shows the
name of the output file produced and what operations are performed.

a.outc89 test1.c
• TNS/R target: Compiles, links (using the default linker
nld), produces non-PIC executable program file.
• TNS/E target: Compiles, links (using the eld linker),
produces PIC (position-independent code) executable
program file.
Compiles, links (using the ld linker for TNS/R target, or
the eld linker for TNS/E target), produces
position-independent code (PIC) executable file.
a.outc89 test1.c -Wcall_shared
Compiles, links, generates symbolic information for
debugging (used by the Inspect debugger for a TNS/R
a.outc89 -g test1.c
target, or the Native Inspect debugger for a TNS/E
target), produces executable program file.
Compiles, does not link, produces object file.test1.oc89 -c test1.c
Compiles, links, produces executable program file.testoutc89 -o testout test1.c
Compiles test2.c, links it with test1.o, produces
executable program file.
testoutc89 -o testout test1.o test2.c
Optimizes an executable program file.testoutc89 -O testout
Beginning with H06.24 and J06.13 RVUs: Compiles
with the LP64 data model, links, produces 64-bit OSS
executable program file.
