LINKFILE
LINKFILE
The LINKFILE pragma invokes the appropriate linker and specifies a command file to
be passed to either:
•
The nld utility when working with conventional code
•
The eld or ld utility when working with PIC (Position-Independent Code), as when
compiling a dynamic-link library (DLL)
file-name
specifies a valid command file for the eld utility, the ld utility, or the nld utility.
•
For syntax and semantics of eld command files, see the eld Manual.
•
For syntax and semantics of ld command files, see the ld Manual.
•
For syntax and semantics of nld command files, see the nld Manual.
The pragma default settings are:
Usage Guidelines
•
On Guardian environment, the LINKFILE pragma must be entered on the
compiler RUN command line for native C and C++.
•
LINKFILE invokes eld or ld rather than nld if you include SHARED or
CALL_SHARED.
•
Use the LINKFILE pragma to specify in a text file the names of the object files or
linkfiles (not source files) that make up a program for linking with a linker utility.
An example of LINKFILE appears in Examples on page 16-12.
•
The C or C++ run-time libraries are linked to the program only if the RUNNABLE
pragma is also specified on Guardian environment. On OSS environment, you
must specifically invoke the linker.
•
The compiler driver does not verify the existence or the readability of the command
file specified in the LINKFILE directive.
