Building NonStop DCE Programs
Note that when linking a TNS/R native PIC program, you must use the ld linker. When
linking a TNS/E native program, you must use the eld linker to link the DLL located at
\$system.zdce.ldce. You must also specify the specify the -WTandem_float flag so
that the program uses TNS floating-point format, and not IEEE floating-point format, as
in the following example:
/usr/bin/c89 -o my_server my_server.c -Wextensions
-Wfileldalign=shared2 -WTandem_float
-Weld="set libname \$system.zdce.ldce"
The TNS/R and TNS/E native environments permit a user application to have a single
user library. To use a private user library in the TNS/R native environment, you must
link your library file with a linkable version of the TNS/R SRL. To use a private user
library in the TNS/E native environment, you must link your library file with the TNS/E
DLL. The TNS/R SRL is available as a Guardian file in the installation subvolume or
target subvolume with one of these file identifiers:
The TNS/E DLL is available as a Guardian file in the installation subvolume or target
subvolume with one of these file identifiers:
To link your library file, use the file /usr/lib/dceul.obey and an appropriately
modified form of the following OSS command line (this example assumes that the
application uses the domestic USA version of the linkable object library):
/usr/bin/nld -o /G/ISV-volume/ISV-subvolume/user-library-name
-ul -verbose -obey /usr/lib/libc.obey -obey /usr/lib/dceul.obey
/G/ISV-volume/ISV-subvolume/LDCEUOBJ

Note that this example uses the nld linker to link a non-PIC library file. Use the ld
linker to link a TNS/R native PIC library file, and use the eld linker to link a TNS/E
native library file.
To rebuild a NonStop DCE TNS application as a TNS/R native application, see the
guidelines in the TNS/R Native Application Migration Guide and the appropriate
programming language manual. To rebuild a NonStop DCE TNS application as a
TNS/E native program, see the guidelines in the TNS/E Native Application Conversion
Guide and the appropriate language manual.
