Linker Options

LINK.exe links Common Object File Format (COFF) object files and libraries to create an executable (.exe) file or a dynamic-link library (DLL).

The following table lists options for LINK.exe. For more information about LINK, see:

On the command line, linker options are not case-sensitive; for example, /base and /BASE mean the same thing. For details on how to specify each option on the command line or in Visual Studio, see the documentation for that option.

You can use the comment pragma to specify some linker options.

Option Purpose

/CLRSUPPORTLASTERROR Preserves the last error code of functions that are called through the P/Invoke mechanism.
/CLRTHREADATTRIBUTE Specifies the threading attribute to apply to the entry point of your CLR program.
/CLRUNMANAGEDCODECHECK Specifies whether the linker will apply the SuppressUnmanagedCodeSecurity attribute to linker-generated PInvoke stubs that call from managed code into native DLLs.
/DEBUG Creates debugging information.
/DEBUGTYPE Specifies which data to include in debugging information.
/DEF Passes a module-definition (.def) file to the linker.
/DEFAULTLIB Searches the specified library when external references are resolved.
/DELAY Controls the delayed loading of DLLs.
/DELAYLOAD Causes the delayed loading of the specified DLL.
/DELAYSIGN Partially signs an assembly.
/DEPENDENTLOADFLAG Sets default flags on dependent DLL loads.
/DLL Builds a DLL.
/DRIVER Creates a kernel mode driver.

/ENTRY Sets the starting address.
/errorReport Reports internal linker errors to Microsoft.
/EXPORT Exports a function.
/FILEALIGN Aligns sections within the output file on multiples of a specified value.
/FIXED Creates a program that can be loaded only at its preferred base address.
/FORCE Forces a link to complete even with unresolved symbols or symbols defined more than once.
/FUNCTIONPADMIN Creates an image that can be hot patched.
/GENPROFILE, /FASTGENPROFILE Both of these options specify generation of a .pgd file by the linker to support profile-guided optimization (PGO). /GENPROFILE and /FASTGENPROFILE use different default parameters.
/GUARD Enables Control Flow Guard protection.
/HEAP Sets the size of the heap, in bytes.
/HIGHENTROPYVA Specifies support for high-entropy 64-bit address space layout randomization (ASLR).
/IDLOUT Specifies the name of the .idl file and other MIDL output files.

/IGNOREIDL Prevents the processing of attribute information into an .idl file.
/IMPLIB Overrides the default import library name.
/INCLUDE Forces symbol references.
/INCREMENTAL Controls incremental linking.
/INTEGRITYCHECK Specifies that the module requires a signature check at load time.
/KEYCONTAINER Specifies a key container to sign an assembly.
/KEYFILE Specifies a key or key pair to sign an assembly.
/LARGEADDRESSAWARE Tells the compiler that the application supports addresses larger than two gigabytes
/LIBPATH Specifies a path to search before the environmental library path.
/LTCG Specifies link-time code generation.
/MACHINE Specifies the target platform.
/MANIFEST Creates a side-by-side manifest file and optionally embeds it in the binary.
/MANIFESTDEPENDENCY Specifies a <dependentAssembly> section in the manifest file.
/MANIFESTFILE Changes the default name of the manifest file.
/MANIFESTINPUT Specifies a manifest input file for the linker to process and embed in the binary. You can use this option multiple times to specify more than one manifest input file.
/MANIFESTUAC Specifies whether User Account Control (UAC) information is embedded in the program manifest.
/MAP Creates a mapfile.
/MAPINFO Includes the specified information in the mapfile.
/MERGE Combines sections.
/MIDL Specifies MIDL command-line options.
/NATVIS Adds debugger visualizers from a Natvis file to the PDB.
/NOASSEMBLY Suppresses the creation of a .NET Framework assembly.
/NODEFAULTLIB Ignores all (or the specified) default libraries when external references are resolved.
/NOENTRY Creates a resource-only DLL.
/NOLOGO Suppresses the startup banner.
/NXCOMPAT Marks an executable as verified to be compatible with the Windows Data Execution Prevention feature.
/OPT Controls LINK optimizations.
/ORDER Places COMDATs into the image in a predetermined order.
/OUT Specifies the output file name.
/PDB Creates a program database (PDB) file.
/PDBALTPATH Uses an alternate location to save a PDB file.
/PDBSTRIPPED Creates a program database (PDB) file that has no private symbols.
/PGD Specifies a .pgd file for profile-guided optimizations.
/POGOSAFEMODE Obsolete Creates a thread-safe PGO instrumented build.
/PROFILE Produces an output file that can be used with the Performance Tools profiler.
/RELEASE Sets the Checksum in the .exe header.
/SAFESEH Specifies that the image will contain a table of safe exception handlers.
/SECTION Overrides the attributes of a section.
/SOURCELINK Specifies a SourceLink file to add to the PDB.

/STUB Attaches an MS-DOS stub program to a Win32 program.
/SUBSYSTEM Tells the operating system how to run the .exe file.
/SWAPRUN Tells the operating system to copy the linker output to a swap file before it is run.
/TLBID Specifies the resource ID of the linker-generated type library.
/TLBOUT Specifies the name of the .tlb file and other MIDL output files.
/TSAWARE Creates an application that is designed specifically to run under Terminal Server.
/USEPROFILE Uses profile-guided optimization training data to create an optimized image.
/VERBOSE Prints linker progress messages.
/VERSION Assigns a version number.
/WHOLEARCHIVE Includes every object file from specified static libraries.
/WINMD Enables generation of a Windows Runtime Metadata file.
/WINMDFILE Specifies the file name for the Windows Runtime Metadata (winmd) output file that's generated by the /WINMD linker option.
