widl – Wine Interface Definition Language (IDL) compiler


widl [options] IDL_file
widl [options] –dlldata-only name1 [name2…]


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 –dll‐
data-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.


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

Header options:

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

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

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

Prefix to put on the name of client stubs.

Prefix to put on the name of server stubs.

-s Generate a server stub file. The default output filename is

–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 desti‐
nation file).

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 directo‐
ries 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:

Ignored, present for midl compatibility.

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

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
