NAME¶

widl - Wine Interface Definition Language (IDL) compiler

SYNOPSIS¶

widl [options] IDL_file
widl [options] --dlldata-only name1 [name2...]

DESCRIPTION¶

When no options are used the program will generate a header file, and possibly client and server stubs, proxy and dlldata files, a typelib, and a UUID file, depending on the contents of the IDL file. If any of the options -c, -h, -p, -s, -t, -u or --local-stubs is given, widl will only generate the requested files, and no others. When run with --dlldata-only, widl will only generate a dlldata file, and it will contain a list of the names passed as arguments. Usually the way this file is updated is that each time widl is run, it reads any existing dlldata file, and if necessary regenerates it with the same list of names, but with the present proxy file included.

When run without any arguments, widl will print a help message.

OPTIONS¶

General options:

-V

Print version number and exit.

-o, --output=name

Set the name of the output file. When generating multiple output files, this sets only the base name of the file; the respective output files are then named name.h, name_p.c, etc.

-b cpu-manufacturer[-kernel]-os

Set the target architecture when cross-compiling. The target specification is in the standard autoconf format as returned by config.sub.

Header options:

-h

Generate header files. The default output filename is infile.h.

--oldnames

Use old naming conventions.

Type library options:

-t

Generate a type library. The default output filename is infile.tlb. If the output file name ends in .res, a binary resource file containing the type library is generated instead.

-m32, -m64

Generate a Win32 or Win64 type library respectively.

UUID file options:

-u

Generate a UUID file. The default output filename is infile_i.c.

Proxy/stub generation options:

-c

Generate a client stub file. The default output filename is infile_c.c.

-Os

Generate inline stubs.

-Oi

Generate old-style interpreted stubs.

-Oif, -Oic, -Oicf

Generate new-style fully interpreted stubs.

-p

Generate a proxy. The default output filename is infile_p.c.

--prefix-all=prefix

Prefix to put on the name of both client and server stubs.

--prefix-client=prefix

Prefix to put on the name of client stubs.

--prefix-server=prefix

Prefix to put on the name of server stubs.

-s

Generate a server stub file. The default output filename is infile_s.c.

--win32, --win64

Only generate 32-bit or 64-bit code respectively (the default is to generate both 32-bit and 64-bit versions into the same destination file).

--rt

Enable additional language extensions for IDL to support WinRT.

Registration script options:

-r

Generate a registration script. The default output filename is infile_r.rgs. If the output file name ends in .res, a binary resource file containing the script is generated instead.

Dlldata file options:

--dlldata-only name1 [name2...]

Regenerate the dlldata file from scratch using the specified proxy names. The default output filename is dlldata.c.

Preprocessor options:

-I path

Add a header search directory to path. Multiple search directories are allowed.

-D id[=val]

Define preprocessor macro id with value val.

-E

Preprocess only.

-N

Do not preprocess input.

Debug options:

-W

Enable pedantic warnings.

-d n

Set debug level to the non negative integer n. If prefixed with 0x, it will be interpreted as an hexadecimal number. For the meaning of values, see the DEBUG section.

Miscellaneous options:

-app_config

Ignored, present for midl compatibility.

--local-stubs=file

Generate empty stubs for call_as/local methods in an object interface and write them to file.

DEBUG¶

Debug level n is a bitmask with the following meaning:
* 0x01 Tell which resource is parsed (verbose mode)
* 0x02 Dump internal structures
* 0x04 Create a parser trace (yydebug=1)
* 0x08 Preprocessor messages
* 0x10 Preprocessor lex messages
* 0x20 Preprocessor yacc trace

Bugs can be reported on the Wine bug tracker.
