Command_Parameters

file-spec [,...]

The CXXLINK facility is layered on top of the OpenVMS Linker utility. The CXXLINK command accepts the same parameters and qualifiers as the OpenVMS Linker utility. Refer to the online help for the OpenVMS Linker utility, HELP LINK, for more information.


Qualifiers

Refer to the online help for the OpenVMS Linker utility, HELP LINK, for information. Additionally, the following qualifiers are accepted by the CXXLINK command:

o /[NO]LOG_FILE [=filename]

o /PRELINK=(option[,option2])

o /REPOSITORY=(writeable-repository[,readonly-repository,...])

o /VERSION


Obsolete_Qualifiers

The following qualifers should no longer be used. Instead, use the corresponding /PRELINK=option qualifier.

Additional Information on:

  • /EXPAND (D)
  • /TEMPLATE_PRELINK (D)

  • /LOG_FILE[=filename]

    /NOLOG_FILE (D)

    This qualifier is obsolete and may be removed in a future release to support new OpenVMS Link Untilty qualifiers. Please use /PRELINK=DEMANGLE instead.


    /PRELINK=(option[,option2])

    Specifies one or more prelink options. If multiple options are specified, they must be enclosed in parentheses and separated by commas. You can specify the following options:

    USE_OBJECT_FILES

    Tells CXXLINK not to use any CXX$LINK.OLB object libraries found in a repository directory. Instead, CXXLINK looks for the specific object files and adds them to the linker options file.

    Use of this qualifier also prevents CXXLINK from creating and populating a CXX$LINK.OLB object library in the repository directory.

    The qualifier is disabled by default and should be used only if CXXLINK fails to link an application correctly.

    TEMPLATE_PRELINK (D) NOTEMPLATE_PRELINK

    Controls whether CXXLINK bypasses the template instantiation process. By default, CXXLINK performs at least one partial link to determine whether there are any unresolved template symbols that need to be instantiated. If you know that your program does not use templates, then you can specify /PRELINK=NOTEMPLATE_PRELINK to bypass this partial link and proceed directly to the final link.

    This qualifier has the same effect as specifying /TEMPLATE_PRELINK or /NOTEMPLATE_PRELINK.

    Because in the future, the OpenVMS Linker Utility might require that /TEMPLATE_PRELINK be removed, it is recommended that users modify their use of CXXLINK to use this new form of the qualifier.

    DEMANGLE_NAMES (D) NODEMANGLE_NAMES

    Controls whether CXXLINK displays unresolved C++ symbols in their mangled or demangled form. By default, CXXLINK displays symbols in their demangled form.

    This qualifier has the same effect as specifying /EXPAND or /NOEXPAND.

    Because in the future, the OpenVMS Linker Utility might require that /EXPAND be removed, it is recommended that users modify their use of CXXLINK to use this new form of the qualifier.

    ADD_INCLUDE_LIBRARIES (D) NOADD_INCLUDE_LIBRARIES

    Controls whether, in initial link fails, CXXLINK adds to the linker options file the names of any object libraries specified on the command line using the /INCLUDE= syntax.

    CXXLINK also checks for any /INCLUDE= library when SYS$INPUT:/OPT is used.

    CXXLINK does not parse any other linker options file for /INCLUDE= syntax.

    Because of the order of dependencies between template instantions and object files, the OpenVMS Linker Utility sometimes fails to extract all the required modules from an object library that was specified using /INCLUDE=. To work around the problem CXXLINK provides that library as input to the linker in its linker options file without the /INCLUDE= syntax, thereby allowing the linker to scan that object library one more time for missing symbols.

    This qualifier should be used only if a CXXLINK user requires more control over which object files are included from a given object library.


    /REPOSITORY=(writeable-repository[,readonly-repository,...])

    Name the repository directories. The first item in the list is considered the writeable repository, and the remaining items (if any) are considered repositories that are read only.

    If you do not specify the /REPOSITORY qualifier, CXXLINK uses the default respository, SYS$DISK:[.CXX_REPOSITORY].


    /VERSION

    Direct CXXLINK to display its version identification and then exit.
