4 winebuild \- Wine dll builder
6 .BI winebuild\ [options]\ [input\ files]
9 generates the C and assembly files that are necessary to build a Wine
10 dll, which is basically a Win32 dll encapsulated inside a Unix
14 has different modes, depending on what kind of file it is asked to
15 generate. The mode is specified by one of the mode options specified
16 below. In addition to the mode option, various other command-line
17 option can be specified, as described in the \fBOPTIONS\fR section.
19 You have to specify exactly one of the following options, depending on
20 what you want winebuild to generate.
23 Build a C file from a .spec file (see \fBSPEC FILE SYNTAX\fR for
24 details), or from a standard Windows .def file. The .spec/.def file
25 is specified via the -E option. The resulting C file must be compiled
26 and linked to the other object files to build a working Wine dll.
29 should be the list of all object files that will be linked into the
32 to get the list of all undefined symbols that need to be imported from
36 Build a C file for an executable. This is basically the same as
37 the --dll mode except that it doesn't require a .spec/.def file as input,
38 since an executable need not export functions. Some executables however
39 do export functions, and for those a .spec/.def file can be specified via
40 the -E option. The executable is named from the .spec/.def file name if
41 present, or explicitly through the -F option. The resulting C file must be
42 compiled and linked to the other object files to build a working Wine
43 executable, and all the other object files must be listed as
47 Build a .def file from a spec file. The .spec file is specified via the
48 -E option. This is used when building dlls with a PE (Win32) compiler.
51 Build a C file containing the definitions for debugging channels. In
54 should be a list of C files to search for debug channel
55 definitions. The resulting C file must be compiled and linked with the
59 Generate the assembly code for the 16-bit relay routines. This is for
60 Wine internal usage only, you should never need to use this option.
63 Generate the assembly code for the 32-bit relay routines. This is for
64 Wine internal usage only, you should never need to use this option.
67 .BI \-C,\ --source-dir= directory
68 Change to the specified directory before reading source files. Only
72 .BI \-d,\ --delay-lib= name
73 Set the delayed import mode for the specified library, which must be
74 one of the libraries imported with the \fB-l\fR option. Delayed mode
75 means that the library won't be loaded until a function imported from
76 it is actually called.
79 Ignored for compatibility with the C compiler.
81 .BI \-e,\ --entry= function
82 Specify the module entry point function; if not specified, the default
89 is not defined, the standard C
91 is used instead). This is only valid for Win32 modules.
93 .BI \-E,\ --export= filename
94 Specify a .spec file (see \fBSPEC FILE SYNTAX\fR for details),
95 or a standard Windows .def file that defines the exports
96 of the DLL or executable that is being built.
99 Ignored for compatibility with the C compiler.
101 .BI \-F,\ --filename= filename
102 Set the file name of the module. The default is to use the base name
103 of the spec file (without any extension).
106 Display a usage message and exit.
108 .BI \-H,\ --heap= size
109 Specify the size of the module local heap in bytes (only valid for
110 Win16 modules); default is no local heap.
112 .BI \-i,\ --ignore= [-]symbol[,[-]symbol]
113 Specify a list of symbols that should be ignored when resolving
114 undefined symbols against the imported libraries. This forces these
115 symbols to be resolved from the Unix C library (or from another Unix
116 library linked with the application). If a symbol is prefixed by '-'
117 it is removed from the list instead of being added; a stand-alone '-'
118 clears the whole list.
121 Ignored for compatibility with the C compiler.
124 Remove the stdcall decorations from the symbol names in the
125 generated .def file. Only meaningful in \fB--def\fR mode.
128 Ignored for compatibility with the C compiler.
130 .BI \--ld-cmd= ld-command
131 Specify the command to use to link the object files; the default is
134 .BI \--nm-cmd= nm-command
135 Specify the command to use to get the list of undefined symbols; the
138 .BI \-L,\ --library-path= directory
139 Append the specified directory to the list of directories that are
140 searched for import libraries.
142 .BI \-l,\ --library= name
143 Import the specified library, looking for a corresponding
144 \fIlibname.def\fR file in the directories specified with the \fB-L\fR
147 .BI \-M,\ --main-module= module
148 Specify that we are building a 16-bit dll, that will ultimately be
149 linked together with the 32-bit dll specified in \fImodule\fR. Only
150 meaningful in \fB--dll\fR mode.
152 .BI \-N,\ --dll-name= dllname
153 Set the internal name of the module. It is only used in Win16
154 modules. The default is to use the base name of the spec file (without
155 any extension). This is used for KERNEL, since it lives in
156 KRNL386.EXE. It shouldn't be needed otherwise.
158 .BI \-o,\ --output= file
159 Set the name of the output file (default is standard output).
161 .BI \-r,\ --res= rsrc.res
162 Load resources from the specified binary resource file. The
163 \fIrsrc.res\fR can be produced from a source resource file with
165 (or with a Windows resource compiler).
167 This option is only necessary for Win16 resource files, the Win32 ones
170 and will automatically be handled correctly (though the
172 option will also work for Win32 files).
174 .BI --subsystem= subsystem[:major[.minor]]
175 Set the subsystem of the executable, which can be one of the following:
178 for a command line executable,
181 for a graphical executable,
184 for a native-mode dll.
186 The entry point of a command line executable is a normal C \fBmain\fR
187 function. A \fBwmain\fR function can be used instead if you need the
188 argument array to use Unicode strings. A graphical executable has a
189 \fBWinMain\fR entry point.
191 Optionally a major and minor subsystem version can also be specified;
192 the default subsystem version is 4.0.
194 .BI --target= cpu-manufacturer[-kernel]-os
195 Specify the target CPU and platform on which the generated code will
196 be built. The target specification is in the standard autoconf format
197 as returned by config.sub.
199 .BI \-u,\ --undefined= symbol
200 Add \fIsymbol\fR to the list of undefined symbols when invoking the
201 linker. This makes it possible to force a specific module of a static
202 library to be included when resolving imports.
205 Display the program version and exit.
209 .SH "SPEC FILE SYNTAX"
211 A spec file should contain a list of ordinal declarations. The general
212 syntax is the following:
215 .RI [ flags ]\ exportname \ \fB(\fR\ [ args... ] \ \fB) \ [ handler ]
217 .IB ordinal\ variable
218 .RI [ flags ]\ exportname \ \fB(\fR\ [ data... ] \ \fB)
221 .RI [ flags ]\ exportname \ [ symbolname ]
224 .RI [ flags ]\ exportname
227 .RI [ flags ]\ exportname\ data
231 Declarations must fit on a single line, except if the end of line is
232 escaped using a backslash character. The
234 character anywhere in a line causes the rest of the line to be ignored
238 specifies the ordinal number corresponding to the entry point, or '@'
239 for automatic ordinal allocation (Win32 only).
242 is a series of optional flags, preceded by a '-' character. The
247 The entry point is not displayed in relay debugging traces (Win32
251 The entry point will be imported by ordinal instead of by name.
254 The function returns a 16-bit value (Win16 only).
257 The function returns a 64-bit value (Win32 only).
260 The entry point is only available on i386 platforms.
263 The function uses CPU register to pass arguments (Win16 only).
266 The function cannot be imported from other dlls, it can only be
267 accessed through GetProcAddress.
268 .SS "Function ordinals"
272 .RI [ flags ]\ exportname \ \fB(\fR\ [ args... ] \ \fB) \ [ handler ]
275 This declaration defines a function entry point. The prototype defined by
276 .IR exportname \ \fB(\fR\ [ args... ] \ \fB)
277 specifies the name available for dynamic linking and the format of the
278 arguments. '@' can be used instead of
280 for ordinal-only exports.
287 for a normal Win32 function
290 for a normal Win16 function
293 for a Win16 or Win32 function using the C calling convention
296 for a Win16 or Win32 function using the C calling convention with a
297 variable number of arguments
301 should be one or several of:
305 (16-bit unsigned value)
320 (linear pointer to a null-terminated ASCII string)
323 (linear pointer to a null-terminated Unicode string)
329 (segmented pointer to a null-terminated ASCII string).
331 .RB Only\ ptr ,\ str ,\ wstr ,\ long\ and\ double
332 are valid for Win32 functions.
336 is the name of the actual C function that will implement that entry
337 point in 32-bit mode. The handler can also be specified as
338 .IB dllname . function
339 to define a forwarded function (one whose implementation is in another
342 is not specified, it is assumed to be identical to
345 This first example defines an entry point for the 32-bit GetFocus()
348 @ stdcall GetFocus() GetFocus
350 This second example defines an entry point for the 16-bit
351 CreateWindow() call (the ordinal 100 is just an example); it also
352 shows how long lines can be split using a backslash:
354 100 pascal CreateWindow(ptr ptr long s_word s_word s_word \\
355 s_word word word word ptr) WIN_CreateWindow
357 To declare a function using a variable number of arguments, specify
360 and declare it in the C file with a '...' parameter for a Win32
361 function, or with an extra VA_LIST16 argument for a Win16 function.
362 See the wsprintf* functions in user.exe.spec and user32.spec for an
364 .SS "Variable ordinals"
367 .IB ordinal\ variable
368 .RI [ flags ]\ exportname \ \fB(\fR\ [ data... ] \ \fB)
370 This declaration defines data storage as 32-bit words at the ordinal
373 will be the name available for dynamic
376 can be a decimal number or a hex number preceded by "0x". The
377 following example defines the variable VariableA at ordinal 2 and
380 2 variable VariableA(-1 0xff 0 0)
382 This declaration only works in Win16 spec files. In Win32 you should
386 .SS "Extern ordinals"
390 .RI [ flags ]\ exportname \ [ symbolname ]
392 This declaration defines an entry that simply maps to a C symbol
393 (variable or function). It only works in Win32 spec files.
395 will point to the symbol
397 that must be defined in the C code. Alternatively, it can be of the
399 .IB dllname . symbolname
400 to define a forwarded symbol (one whose implementation is in another
403 is not specified, it is assumed to be identical to
409 .RI [ flags ]\ exportname
411 This declaration defines a stub function. It makes the name and
412 ordinal available for dynamic linking, but will terminate execution
413 with an error message if the function is ever called.
414 .SS "Equate ordinals"
418 .RI [ flags ]\ exportname\ data
420 This declaration defines an ordinal as an absolute value.
422 will be the name available for dynamic linking.
424 can be a decimal number or a hex number preceded by "0x".
427 has been worked on by many people over the years. The main authors are
428 Robert J. Amstadt, Alexandre Julliard, Martin von Loewis, Ulrich
429 Weigand and Eric Youngdale. Many other Wine developers have
430 contributed, please check the file Changelog in the Wine distribution
431 for the complete details.
433 It is not yet possible to use a PE-format dll in an import
434 specification; only Wine dlls can be imported.
