Mixed-Language Programs
Programs With Embedded NonStop SQL/MP
Note. You can only link linkfiles into a program. You cannot link loadfiles, or a combination of
loadfiles and linkfiles, into a program.
C Programs
C programs require access to their run-time environments. To create an executable C
program, you must link to the run-time environment initialization code and the shared
run-time libraries (SRLs) your program uses. The NMC and c89 compilers
automatically link to the required items. If you use nld directly to link a C program, you
must specify these items in nld options.
Follow these step to create an executable C program using nld:
1. Link together the object code files that you compiled.
2. Link to the C run-time library initialization object code file:
Environment
Guardian
OSS
3. Link to the SRLs that your program uses. To link the standard set of C SRLs, use
the following options:
Environment
Guardian
OSS
4. If your program uses active backup programming functions, such as
__ns_start_backup(), link to the active backup programming support object
code file:
Environment
Guardian
OSS
