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 /MODEL=[ANSI | ARM]
o /PREINST
o /PRELINK=(option[,option2])
o /REPOSITORY=(writeable-repository[,readonly-repository,...])
o /USE_LINK_INPUT[=filename]
o /VERSION
Obsolete_Qualifiers
The following qualifers should no longer be used. Instead, use the
corresponding /PRELINK=option qualifier.
/LOG_FILE[=filename]
/LOG_FILE[=filename]
/NOLOG_FILE (D)
Turns on verbose or verify mode to write each phase of
instantiation to the specified log file. This option is
useful as a debugging aid.
/MODEL=[ANSI | ARM]
/MODEL=ANSI (D)
Link with /MODEL=ANSI versions of the C++ libraries.
See CXX/MODEL=ANSI for details.
/PREINST
/PREINST (D)
/NOPREINST
Forces the standard library template instantiations in the
user's repository to be preferred at link time over the ones in the
standard library. This is useful, for example, if you want debugging
versions of the instantiations. This option is useful only when used
in conjunction with CXX/DEFINE=__FORCE_INSTANTATIONS.
/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 (D)
Tells CXXLINK not to use the CXX$LINK.OLB library found in a
repository directory. Instead, CXXLINK looks for the specific
object files and adds them to the linker options file.
Use of this qualifier also prevents CXXLINK from creating and
populating a CXX$LINK.OLB object library in the repository
directory.
USE_OLB
Tells CXXLINK to use the CXX$LINK.OLB found in a repository directory.
Specifying this option might improve link-time performance but in
some cases could produce unresolved template symbols.
TEMPLATE_PRELINK (D)
NOTEMPLATE_PRELINK
Controls whether CXXLINK bypasses the template instantiation process. By
default, CXXLINK performs at least one partial link to determine whether
there are any unresolved template symbols that need to be instantiated.
If you know that your program does not use templates, then you can
specify /PRELINK=NOTEMPLATE_PRELINK to bypass this partial link and
proceed directly to the final link.
This qualifier has the same effect as specifying /TEMPLATE_PRELINK or
/NOTEMPLATE_PRELINK.
Because in the future, the OpenVMS Linker Utility might require that
/TEMPLATE_PRELINK be removed, it is recommended that users
modify their use of CXXLINK to use this new form of the qualifier.
ADD_INCLUDE_LIBRARIES (D)
NOADD_INCLUDE_LIBRARIES
Controls whether, if initial link fails, CXXLINK adds to the linker
options file the names of any object libraries specified on the command
line using the /INCLUDE= syntax.
CXXLINK also checks for any /INCLUDE= library when SYS$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$DISK:[.CXX_REPOSITORY].
/USE_LINK_INPUT[=filename]
/USE_LINK_INPUT[=filename]
/NOUSE_LINK_INPUT (D)
By default, CXXLINK creates a temporary .OPT file in the
[.cxx_repository] directory. If the [.cxx_repository]
directory does not exist, the .OPT file is created in the
users current directory. CXXLINK deletes this file.
If you specify /USE_LINK_INPUT, CXXLINK saves the option file passed
to LINK in a file named CXX_REPOSITORY.OPT in the user's current
directory (SYS$DISK:[]CXX_REPOSITORY.OPT). CXXLINK does not delete
this file.
If you specify /USE_LINK_INPUT=filename CXXLINK saves the option
file passed to LINK in the filename specified. Because the temporary
file that CXXLINK uses is renamed to the file name specified,
"filename" must reside on the same disk as the [.CXX_REPOSITORY]
directory. CXXLINK does not delete this file.
/VERSION
Direct CXXLINK to display its version identification and then exit.
Customer_feedback
Customers with support contracts should seek support for problems through
local customer support centers.
Customers who do not have support contracts are encouraged to mail problem
reports to
compaq_cxx.bugs@compaq.com
Although these reports will certainly be used as a source of input
for fixing problems for new releases, we cannot give the reports
individual attention. We can take remedial action only on a best-effort
basis.
If you have questions, suggestions, or comments, please send mail to
compaq_cxx@compaq.com
When reporting problems to Compaq, please provide the following
information:
o Name and version of compiler (from a listing file)
o Name and version of operating system
o Smallest possible complete source and commands needed to
reproduce the problem
o An example of the incorrect results and the desired results
