1 LINK

Invokes the OpenVMS Linker utility to link one or more input files into a program image and defines the execution characteristics of the image. For a complete description of the linker, including more information about the LINK command, see the OpenVMS Linker Utility Manual. Format LINK file-spec [,...] 2 Parameters file-spec Specifies one or more input files (wildcard characters are not allowed). Input files can be object modules, shareable images, libraries to be searched for external references or from which specific modules are to be included, or options files to be read by the linker. Separate multiple input file specifications with commas (,) or plus signs (+). In either case, the linker creates a single image file. If you omit the file type in an input file specification, the linker supplies default file types, based on the nature of the input file. For object modules, the default file type is .OBJ. 2 Qualifiers /ALPHA Directs the linker to produce an OpenVMS Alpha image. The default action, when neither /ALPHA nor /VAX is specified, is to create an OpenVMS VAX image on an OpenVMS VAX system and to create an OpenVMS Alpha image on an OpenVMS Alpha system. /BPAGE /BPAGE[=page-size-indicator] Specifies the page size the linker should use when it creates the image sections that make up an image. The page-size-indicatior specifies a page size as the power of 2 required to create a page that size. For example, to get an 8KB page size, specify the value 13 because 2**13 equals 8K. The following table lists the page sizes supported by the linker with the defaults: Page Value Size Defaults 9 512 Default value for VAX links when the /BPAGE bytes qualifier is not specified. 13 8 KB Default value for VAX links when the /BPAGE qualifier is specified without a value. 14 16 KB - 15 32 KB - 16 64 KB Default value for Alpha links when /BPAGE is not specified or when the /BPAGE qualifier is specified without a value. /BRIEF /MAP/BRIEF Directs the linker to produce a brief image map. For more information, see also the /MAP and /FULL qualifiers. /CONTIGUOUS /CONTIGUOUS /NOCONTIGUOUS (default) Directs the linker to place the entire image in consecutive disk blocks. If sufficient contiguous space is not available on the output disk, the linker reports an error and terminates the link operation. /CROSS_REFERENCE /MAP/CROSS_REFERENCE /MAP/NOCROSS_REFERENCE (default) Directs the linker to replace the Symbols By Name section in a full or default image map with the Symbol Cross-Reference section. /DEBUG /DEBUG[=file-spec] /NODEBUG (default) Directs the linker to generate a debugger symbol table (DST) using DBG and TBT object language records and to give the debugger control when the image is run. If you specify the /DEBUG qualifier without entering a file specification, the OpenVMS Debugger gains control at run time. Requesting the OpenVMS Debugger does not affect the location of code within the image because the debugger is mapped into the process address space at run time, not at link time. See the OpenVMS Debugger Manual for additional information. If you specify the /DEBUG qualifier with a file specification, the user-written debugger module that the file specification identifies gains control at run time. The linker assumes a default file type of .OBJ. Requesting a user-written debugger module does affect the location of code within the image because the linker together with program code processes the debugger module code. /DEMAND_ZERO /DEMAND_ZERO (default) /DEMAND_ZERO[=per_page] /NODEMAND_ZERO For Alpha linking, enables demand-zero image section production for both executable and shareable images. Per-page enables the linker to perform demand-zero compression on Alpha images on a per-page basis. If this keyword is not used, the linker performs demand-zero compression on an image-section basis only. /DSF /DSF[=file-spec] /NODSF (default) For Alpha linking, directs the linker to create a file called a debug symbol file (DSF) for use by the OpenVMS Debugger or the OpenVMS Alpha System-Code Debugger. The file-spec specifies the character string you want the linker to use as the name of the debug symbol file. If you do not include a file type in the character string, the linker appends the .DSF file type to the file name. If you specify the /DSF qualifier without the file specification, the linker creates a debug symbol file with the file name of the first input file and the default file type .DSF. If you append the /DSF qualifier to one of the input file specifications, the linker creates a debug symbol file with the file name of the file to which the qualifier is appended and with the default file type .DSF. The OpenVMS Debugger (whether you use it in System-Code Debugger mode or user mode) requires that the name of the DSF file be the same as the name of the image file, except that the file extension is .DSF. If you use an /EXECUTABLE or /SHAREABLE qualifier and a file name with the LINK command, you must also include the same file name with the /DSF qualifier. (You must use the .DSF file type.) /EXECUTABLE /EXECUTABLE[=file-spec] (default) /NOEXECUTABLE Directs the linker to create an executable image, as opposed to a shareable image or a system image. The file-spec specifies the character string you want the linker to use as the name of the image file that the link operation produces. If you do not specify a file type in the character string, the linker assigns the .EXE file type by default. If you do not specify a file name with the /EXECUTABLE qualifier, the linker creates an executable image with the file name of the first input file. If you append the /EXECUTABLE qualifier to an input file specification, the linker creates an executable image with the file name of the file to which the qualifier is appended. /FULL /MAP/FULL Directs the linker to create a full image map file. For more information, see also the /MAP, /CROSS_REFERENCE, and /BRIEF qualifiers. /GST /GST (default) /NOGST For Alpha linking, directs the linker to include in the global symbol table (GST) of a shareable image those symbols that have been declared as universal symbols in a symbol vector. /HEADER When specified with the /SYSTEM qualifier, directs the linker to include an image header in a system image. /INCLUDE library-name/INCLUDE=(module-name[,...]) Identifies the input file specification to which it is appended as a library file and directs the linker to include in the link operation the module or modules specified as the value of the qualifier. The library-name specifies the name of the library from which you want a module or modules to be extracted. The file name must specify a library file. The linker assumes the default file type of .OLB. The module-name specifies the module or modules that you want to extract from the library. To specify more than one module, enclose the list in parentheses and separate the module names with commas. /INFORMATIONALS /INFORMATIONALS (default) /NOINFORMATIONALS Directs the linker to output informational messages produced by a link operation. /LIBRARY library-name/LIBRARY Identifies the input file specification to which it is appended as a library file and directs the linker to process the library's name table as part of its symbol resolution processing. When the linker finds in the library the definition of a symbol referenced in a previously processed input file, the linker includes from the library the module in which the symbol is defined. The library-name specifies the name of the library to be included in the link operation. You must specify a library file name. The linker assumes the default file type of .OLB. /MAP /MAP[=file-spec] (default in batch mode) /NOMAP (default in interactive mode) Directs the linker to create an image map file. For more information, see also the /BRIEF, /CROSS_REFERENCE, and /FULL qualifiers. If you enter a file specification with the /MAP qualifier, the linker creates an image map file with that file name. If you do not enter a file type after the file name, the linker assumes a file type of .MAP. If you do not enter a file specification with the /MAP qualifier, the linker creates an image map file with the file name of the first input file specified on the command line and the file type .MAP. (If no input files are specified on the command line, the linker names the map file .MAP.) If you append the /MAP qualifier to one of the input file specifications, the linker creates an image map file with the file name of the file to which the qualifier is appended, using the .MAP file type. /NATIVE_ONLY /NATIVE_ONLY (default) /NONATIVE_ONLY For Alpha linking, prevents the linker from passing along procedure signature block (PSB) information in special fix-ups to the image activator. The image activator uses this information to build jackets so that native OpenVMS Alpha images can call translated OpenVMS VAX images. Note that this qualifier does not prevent incoming calls from translated OpenVMS VAX images. /OPTIONS options-file-name/OPTIONS Identifies the input file specification to which it is appended as a linker options file. The options-file-name is the file specification of a linker options file. The linker assumes the file type .OPT by default. /P0IMAGE Directs the linker to place an executable image entirely in P0 address space. When the /P0IMAGE qualifier is specified, the user stack and OpenVMS RMS buffers, which usually reside in P1 space, are placed in P0 space by the image activator. /PROTECT /PROTECT /NOPROTECT (default) Directs the linker to protect an entire shareable image from user-mode write access and supervisor-mode write access. Must be specified with the /SHAREABLE qualifier. /REPLACE /REPLACE (default) /NOREPLACE For Alpha linking, specifies that the linker should perform certain optimizations to improve the performance of the resultant image when instructed by the compiler. /SECTION_BINDING /SECTION_BINDING=(CODE,DATA) /NOSECTION_BINDING (default) For Alpha linking, directs the linker to create an image that can be installed as a resident image and to flag coding practices in the image that would prevent this. CODE prevents the linker from replacing the Jump to Subroutine (JSR) instruction sequence with the more efficient Branch to Subroutine (BSR) instruction sequence when the target of the branch crosses an image section boundary. DATA directs the linker to check for address calculations that create dependencies on the layout of data image sections. The linker reports such occurrences. When the /SECTION_BINDING qualifier is specified without either the CODE or DATA keyword, the linker performs both types of checking by default. /SELECTIVE_SEARCH input-file-name/SELECTIVE_SEARCH When you append this qualifier to an input file specification, the linker processes only those symbols in the input file that are referenced by previously processed input files. The input-file-name is the name of the input file you want included in the link operation. The /SELECTIVE_SEARCH qualifier works only with object modules and shareable images. This qualifier is illegal with library files. (To process the modules in a library selectively, specify the /SELECTIVE_SEARCH qualifier when inserting the files into the library. For more information, see the OpenVMS Command Definition, Librarian, and Message Utilities Manual.) /SHAREABLE /SHAREABLE[=file-spec] shareable-image-file-name/SHAREABLE When specified anywhere on the link command line, the /SHAREABLE qualifier directs the linker to create a shareable image. When you append the /SHAREABLE qualifier to a file specification in a linker options file, the system identifies the input file as a shareable image. When you use the /SHAREABLE qualifier to create a shareable image, the file-spec specifies the name you want the linker to assign to the shareable image being created. If you do not include a file specification, the linker assigns the shareable image the name of the file to which you append the /SHAREABLE qualifier in the LINK command line. If you do not append the /SHAREABLE qualifier to an input file specification, the linker assigns to the shareable image the name of the first input file specified on the command line using the extension .EXE. If you designate a file name but omit the file type, the linker assigns the shareable image the file type .EXE. The shareable-image-file-name specifies the name of a shareable image. Note that you can use the /SHAREABLE qualifier to identify a shareable image only in a linker options file. It is illegal to include a shareable image in a link operation by specifying it on the LINK command line. /SYMBOL_TABLE /SYMBOL_TABLE[=file-spec] /NOSYMBOL_TABLE (default) Directs the linker to create a symbol table file. The file-spec specifies the character string you want the linker to use as the name of the symbol table file. If you do not include a file type in the character string, the linker appends the .STB file type to the file name. If you specify the /SYMBOL_TABLE qualifier without the file specification, the linker creates a symbol table file with the file name of the first input file and the default file type .STB. If you append the /SYMBOL_TABLE qualifier to one of the input file specifications, the linker creates a symbol table file with the file name of the file to which the qualifier is appended, with the default file type .STB. /SYSEXE /SYSEXE[=[NO]SELECTIVE] /NOSYSEXE (default) For Alpha linking, directs the linker to process the system shareable image, SYS$BASE_IMAGE.EXE, in a link operation. The linker looks for SYS$BASE_IMAGE.EXE in the directory that the logical name ALPHA$LOADABLE_IMAGES points to. When you specify the SELECTIVE keyword, the linker processes the SYS$BASE_IMAGE.EXE file selectively, including only those symbols from the global symbol table of the SYS$BASE_IMAGE.EXE file that were referenced by input files previously processed in the link operation. When you specify the /SYSEXE qualifier without a keyword, the linker processes the executive image selectively. When you specify the NOSELECTIVE keyword, the linker includes all the symbols from the SYS$BASE_IMAGE.EXE global symbol table in the link operation. When you specify the /SYSEXE qualifier without a keyword, the linker processes the executive image selectively. /SYSLIB /SYSLIB (default) /NOSYSLIB Directs the linker to process the default system shareable image library, IMAGELIB.OLB, and the default system object module library, STARLET.OLB, to resolve symbolic references that remain undefined after all specified input files and any default user libraries have been processed. /SYSSHR /SYSSHR (default) /NOSYSSHR Directs the linker to process the default system shareable image library (IMAGELIB.OLB) to resolve symbolic references that remain undefined after all specified input files and any user libraries have been processed. /SYSTEM /SYSTEM[=base-address] Directs the linker to create a system image and optionally allows you to specify the address at which the image should be loaded into memory. A system image cannot be activated with the RUN command; it must be bootstrapped or otherwise loaded into memory. The base-address specifies the address at which the image is to be loaded in virtual memory. You can specify a base address in hexadecimal (%X), octal (%O), or decimal (%D) format. The default base address is %X80000000. Note that if you specify the /HEADER qualifier, the linker adjusts the base address to the next highest page boundary if it is not already a page boundary. The next highest page boundary is the smallest number that is greater than the value specified in the base-address parameter and that is divisible by the default page size (which is architecture-specific) or the page size specified using the /BPAGE qualifier. /THREADS_ENABLE /THREADS_ENABLE[=(MULTIPLE_KERNEL_THREADS,UPCALLS)]) /NOTHREADS_ENABLE (default) Kernel threads allow a multithreaded application to have a thread executing on every CPU in a multiprocessor system. The /THREADS_ENABLE qualifier allows you to turn kernel threads on and off on a per-image basis. When you specify this qualifier, the OpenVMS linker sets the appropriate bits in the image header of the image being linked. These bits control the following: o Whether the image is allowed to enter a multiple kernel threads environment o Whether the image can receive upcalls from the OpenVMS scheduler On Alpha systems, the MULTIPLE_KERNEL_THREADS keyword sets the MULTIPLE_KERNEL_THREADS bit in the image header of the image being built. This bit indicates to the image activator that the image can be run in a multiple kernel threads environment. If you specify this keyword for OpenVMS VAX links, it is ignored. The UPCALLS keyword sets the UPCALLS bit in the OpenVMS image header of the image being built. This bit indicates to the image activator that the process can receive upcalls from the OpenVMS scheduler. /TRACEBACK /TRACEBACK (default) /NOTRACEBACK Directs the linker to include traceback information in the image file. If you specify the /DEBUG qualifier, the linker includes traceback information by default, overriding the /NOTRACEBACK qualifier if it is specified. /USERLIBRARY /USERLIBRARY[=(table[,...])] /USERLIBRARY=ALL (default) /NOUSERLIBRARY Directs the linker to process one or more default user libraries to resolve symbolic references that remain undefined after all specified input files have been processed. Table specifies the logical name tables that the linker searches for default user libraries. The following keywords are the only acceptable parameter values: Keyword Description ALL Directs the linker to search the process, group, and system logical name tables for default user library definitions. This is the default. GROUP Directs the linker to search the group logical name table for default user library definitions. NONE Directs the linker not to search any logical name table; the /USERLIBRARY=NONE qualifier is equivalent to the /NOUSERLIBRARY qualifier. PROCESS Directs the linker to search the process logical name table for default user library definitions. SYSTEM Directs the linker to search the system logical name table for default user library definitions. /VAX Directs the linker to produce an OpenVMS VAX image. The default action, when neither /ALPHA nor /VAX is specified, is to create an OpenVMS VAX image on an OpenVMS VAX system and to create an OpenVMS Alpha image on an OpenVMS Alpha system.
