Command-Line Elements
The linker can also use a configuration file called ILINK32.CFG for options that you'd typically type at the command line.
Element | Description |
---|---|
|
A response file is an ASCII file that lists linker options and file names that you would normally type at the command line. By placing options and file names in a response file, you can save the amount of keystrokes you need to type to link your application. |
|
Linker options that control how the linker works. For example, options specify whether to produce an .EXE, .BPL, or .DLL file. Linker options must be preceded by either a slash ( |
|
An initialization module for executables or DLLs that arranges the order of the various segments of the program. Failure to link in the correct initialization module usually results in a long list of error messages telling you that certain identifiers are unresolved, or that no stack has been created. |
|
The .OBJ files you want linked. Specify the path if the files are not in the current directory. (The linker appends an .OBJ extension if no extension is present.) This section is also where you would put import libraries for Delphi packages ( |
|
The name you want to be given to the executable file (.EXE, .BPL, or .DLL). If you do not specify an executable file name, ILINK32 derives the name of the executable by appending .EXE, .BPL, or .DLL to the first object file name listed. (The linker assumes or appends an .EXE extension for executable files if no extension is present. It also appends a .DLL extension for dynamic link libraries if no extension is present. Similarly, the linker appends a .BPL extension for package files if no extension is present.) |
|
The name you want to be given to the map file. If you do not specify a name, the map file name is the same as the .EXE file (but with the .MAP extension). (The linker appends a .MAP extension if you do not specify an extension.) |
|
The library files you want to be included at link time. Do not use commas to separate the libraries listed. If a file is not in the current directory or the search path (see the

Builds a 32-bit Windows console application. |
|
Specifies the image base address and removes the relocation table. |
|
Specifies the image base address, and preserves DLL relocation table. Successive objects are aligned on 64K linear address boundaries. Improves load-time and run-time performance.
Recommended for producing DLLs. |
|
Refreshes the linker state files . Erases all linker state files before each link; then recreates the files and continues with the link. |
|
Treats case as significant in public and external symbols. |
|
Delay-loads a DLL. The specified DLL is not loaded or initialized until an entry point in the DLL is actually called. |
|
Saves the specified description in the PE image. |
|
Specifies the max. number of errors. |
|
Inserts a comment string into the image directly after the object table in the PE file header. You can specify more than one string. |
|
Generates a Delphi-compatible RC file (DRC file). |
|
Sets image flags. The xxxx flags are:
|
|
Keeps output files on error. |
|
Generates a .LIB file. |
|
Generates design-time-only package. Default is: the package works at both design time and run time. |
|
Generates run-time-only package. Default is: the package works at both design time and run time. |
|
Do not generate linker state files (disable incremental linking). Subsequent links will take just as long as the first one. Default is Off. |
|
Set section flags. Adds the specified flags to the existing flags for a given section, but cannot remove default flags from a section. Section flags are: Example -Gs:.rsrc=W This switch makes the RSRC section writable. |
|
Calculate checksum of target and insert result in PE header. Used for NT Kernel mode drivers and system DLLs. |
|
Specifies application heap reserve size in hex or decimal. Minimum value is 0. This switch overrides the HEAPSIZE setting in a module definition file. |
|
Specifies application heap commit size. |
|
Specifies the directory for intermediate output files. Directs linker state files, but the map debug file and TDS debug file are saved in the same directory as the output image, unless otherwise specified for the MAP file. |
|
Specifies object search paths. Example ILINK32 /jc:\myobjs;.\objs splash ^ .\common\logo,,,utils logolib This command directs the linker to first search the current directory for SPLASH.OBJ. If the file is not found in the current directory, the linker then searches the C:\MYOBJS directory, and then the .\OBJs directory. However, the linker does not use the object search paths to find the file LOGO.OBJ because an explicit path was given for this file. |
|
Specifies the library search path to use if no explicit path is given for the LIB file and the linker cannot find the LIB file in the current directory. ILINK32 /Lc:\mylibs;.\libs splash ^ .\common\logo,,,utils logolib directs the linker to first search the current directory for SPLASH.LIB. If the file is not found in the current directory, the linker then searches the C:\MYLIBS directory, and then the .\LIBs directory. However, the linker does not use the library search paths to find the file LOGO.LIB because an explicit path was given for this file. |
|
Prints the mangled C++ identifiers in the map file, not the full name. |
|
The segment listing has a line for each segment, showing the segment starting address, segment length, segment name, and the segment class. The public symbols are broken down into two lists, the first showing the symbols sorted alphabetically, the second showing the symbols in increasing address order. Symbols with absolute addresses are tagged |
|
Suppresses command line banner. |
|
Verbose linking. Default is Off. |
|
Replaces resources. |
|
Specifies application stack reserve size. |
|
Specifies application stack commit size. |
|
Produces a detailed map file of segments by adding details such as group and module information to the default map file produced by the linker. |
|
Targets a 32-bit Windows DLL file. |
|
Targets a 32-bit Windows EXE file. |
|
Generates a package. |

Linker Response Files
You can use response files with the command-line linker to specify linker options.
Response files are ASCII files that list linker options and file names that you would normally type at the command line. Response files allow you longer command lines than most operating systems support, plus you do not have to continually type the same information. Response files can include the same information as configuration files, but they also support the inclusion of file names.
Unlike the command line, a response file can be several lines long. To specify an added line, end a line with a plus character (+
) and continue the command on the next line. Note that if a line ends with an option that uses the plus to turn it on (such as /v+
), the +
is not treated as a line continuation character (to continue the line, use /v+ +
).
If you separate command-line components (such as .OBJ files from .LIB files) by lines in a response file, you must leave out the comma used to separate them on the command line.
For example:
/c c0ws+ myprog,myexe + mymap + mylib cws
leaves out the commas you would have to type if you put the information on the command line:
ILINK32 /c c0ws myprog,myexe,mymap,mylib cws
To use response files:
- Type the command-line options and file names into an ASCII text file and save the file. Response files typically have an .RSP extension.
- Type:
ILINK32 @[<path>]<RESFILE.RSP>
- where
<RESFILE.RSP>
is the name of your response file.
You can specify more than one responses file, as follows:
ilink32 /c @listobjs.rsp,myexe,mymap,@listlibs.rsp
Note: You can add comments to response files using semicolons; the linker ignores any text on a line that follows a semicolon.
Using ILINK32 with BCC32.EXE
You can pass options and files to ILINK32 through the command-line compiler (BCC32.EXE) by typing file names on the command line with explicit .OBJ and .LIB extensions. For example, this command:
BCC32 mainfile.obj sub1.obj mylib.lib
links MAINFILE.OBJ, SUB1.OBJ, and MYLIB.LIB to produce the executable MAINFILE.EXE.
Note: By default, BCC32 starts ILINK32 with the files C0W32.OBJ, CW32.LIB, and IMPORT32.LIB (initialization module, run-time library, and Windows import library). In addition, both the Delphi and C++ compilers always pass the linkers the
/c
(case-sensitive link) option.
