4 winebuild \- Wine dll builder
6 .BI winebuild\ [options]\ [input\ files]
9 generates the assembly files that are necessary to build a Wine dll,
10 which is basically a Win32 dll encapsulated inside a Unix library.
13 has different modes, depending on what kind of file it is asked to
14 generate. The mode is specified by one of the mode options specified
15 below. In addition to the mode option, various other command-line
16 option can be specified, as described in the \fBOPTIONS\fR section.
18 You have to specify exactly one of the following options, depending on
19 what you want winebuild to generate.
22 Build an assembly file from a .spec file (see \fBSPEC FILE SYNTAX\fR
23 for details), or from a standard Windows .def file. The .spec/.def
24 file is specified via the -E option. The resulting file must be
25 assembled and linked to the other object files to build a working Wine
26 dll. In this mode, the
28 should be the list of all object files that will be linked into the
31 to get the list of all undefined symbols that need to be imported from
35 Build an assembly file for an executable. This is basically the same as
36 the --dll mode except that it doesn't require a .spec/.def file as input,
37 since an executable need not export functions. Some executables however
38 do export functions, and for those a .spec/.def file can be specified via
39 the -E option. The executable is named from the .spec/.def file name if
40 present, or explicitly through the -F option. The resulting file must be
41 assembled and linked to the other object files to build a working Wine
42 executable, and all the other object files must be listed as
46 Build a .def file from a spec file. The .spec file is specified via the
47 -E option. This is used when building dlls with a PE (Win32) compiler.
50 Generate the assembly code for the 16-bit relay routines. This is for
51 Wine internal usage only, you should never need to use this option.
54 Generate the assembly code for the 32-bit relay routines. This is for
55 Wine internal usage only, you should never need to use this option.
58 .BI \--as-cmd= as-command
59 Specify the command to use to compile assembly files; the default is
62 .BI \-b,\ --target= cpu-manufacturer[-kernel]-os
63 Specify the target CPU and platform on which the generated code will
64 be built. The target specification is in the standard autoconf format
65 as returned by config.sub.
67 .BI \-d,\ --delay-lib= name
68 Set the delayed import mode for the specified library, which must be
69 one of the libraries imported with the \fB-l\fR option. Delayed mode
70 means that the library won't be loaded until a function imported from
71 it is actually called.
74 Ignored for compatibility with the C compiler.
76 .BI \-e,\ --entry= function
77 Specify the module entry point function; if not specified, the default
82 for executables (if the standard C
86 is used instead). This is only valid for Win32 modules.
88 .BI \-E,\ --export= filename
89 Specify a .spec file (see \fBSPEC FILE SYNTAX\fR for details),
90 or a standard Windows .def file that defines the exports
91 of the DLL or executable that is being built.
93 .B \--external-symbols
94 Allow linking to external symbols directly from the spec
95 file. Normally symbols exported by a dll have to be defined in the dll
96 itself; this option makes it possible to use symbols defined in
97 another Unix library (for symbols defined in another dll, a
99 specification must be used instead).
102 Ignored for compatibility with the C compiler.
104 .BI \-F,\ --filename= filename
105 Set the file name of the module. The default is to use the base name
106 of the spec file (without any extension).
109 Display a usage message and exit.
111 .BI \-H,\ --heap= size
112 Specify the size of the module local heap in bytes (only valid for
113 Win16 modules); default is no local heap.
115 .BI \-i,\ --ignore= [-]symbol[,[-]symbol]
116 Specify a list of symbols that should be ignored when resolving
117 undefined symbols against the imported libraries. This forces these
118 symbols to be resolved from the Unix C library (or from another Unix
119 library linked with the application). If a symbol is prefixed by '-'
120 it is removed from the list instead of being added; a stand-alone '-'
121 clears the whole list.
124 Ignored for compatibility with the C compiler.
127 Remove the stdcall decorations from the symbol names in the
128 generated .def file. Only meaningful in \fB--def\fR mode.
131 Ignored for compatibility with the C compiler.
133 .BI \--ld-cmd= ld-command
134 Specify the command to use to link the object files; the default is
137 .BI \-L,\ --library-path= directory
138 Append the specified directory to the list of directories that are
139 searched for import libraries.
141 .BI \-l,\ --library= name
142 Import the specified library, looking for a corresponding
143 \fIlibname.def\fR file in the directories specified with the \fB-L\fR
147 Generate 32-bit, respectively 64-bit code.
149 .BI \-M,\ --main-module= module
150 Specify that we are building a 16-bit dll, that will ultimately be
151 linked together with the 32-bit dll specified in \fImodule\fR. Only
152 meaningful in \fB--dll\fR mode.
154 .BI \-N,\ --dll-name= dllname
155 Set the internal name of the module. It is only used in Win16
156 modules. The default is to use the base name of the spec file (without
157 any extension). This is used for KERNEL, since it lives in
158 KRNL386.EXE. It shouldn't be needed otherwise.
160 .BI \--nm-cmd= nm-command
161 Specify the command to use to get the list of undefined symbols; the
164 .BI --nxcompat= yes|no
165 Specify whether the module is compatible with no-exec support. The
168 .BI \-o,\ --output= file
169 Set the name of the output file (default is standard output). If the
170 output file name end in \fB.o\fR, the text output is sent to a
171 temporary file that is then assembled to produce the specified .o
174 .BI \-r,\ --res= rsrc.res
175 Load resources from the specified binary resource file. The
176 \fIrsrc.res\fR file can be produced from a source resource file with
178 (or with a Windows resource compiler).
180 This option is only necessary for Win16 resource files, the Win32 ones
183 and will automatically be handled correctly (though the
185 option will also work for Win32 files).
188 Do not delete the various temporary files that \fBwinebuild\fR generates.
190 .BI --subsystem= subsystem[:major[.minor]]
191 Set the subsystem of the executable, which can be one of the following:
194 for a command line executable,
197 for a graphical executable,
200 for a native-mode dll,
205 The entry point of a command line executable is a normal C \fBmain\fR
206 function. A \fBwmain\fR function can be used instead if you need the
207 argument array to use Unicode strings. A graphical executable has a
208 \fBWinMain\fR entry point.
210 Optionally a major and minor subsystem version can also be specified;
211 the default subsystem version is 4.0.
213 .BI \-u,\ --undefined= symbol
214 Add \fIsymbol\fR to the list of undefined symbols when invoking the
215 linker. This makes it possible to force a specific module of a static
216 library to be included when resolving imports.
219 Display the various subcommands being invoked by
223 Display the program version and exit.
227 .SH "SPEC FILE SYNTAX"
229 A spec file should contain a list of ordinal declarations. The general
230 syntax is the following:
233 .RI [ flags ]\ exportname \ \fB(\fR\ [ args... ] \ \fB) \ [ handler ]
235 .IB ordinal\ variable
236 .RI [ flags ]\ exportname \ \fB(\fR\ [ data... ] \ \fB)
239 .RI [ flags ]\ exportname \ [ symbolname ]
242 .RI [ flags ]\ exportname
245 .RI [ flags ]\ exportname\ data
249 Declarations must fit on a single line, except if the end of line is
250 escaped using a backslash character. The
252 character anywhere in a line causes the rest of the line to be ignored
256 specifies the ordinal number corresponding to the entry point, or '@'
257 for automatic ordinal allocation (Win32 only).
260 is a series of optional flags, preceded by a '-' character. The
265 The entry point is not displayed in relay debugging traces (Win32
269 The entry point will be exported by ordinal instead of by name. The
270 name is still available for importing.
273 The function returns a 16-bit value (Win16 only).
276 The function returns a 64-bit value (Win32 only).
279 The function uses CPU register to pass arguments.
282 The function cannot be imported from other dlls, it can only be
283 accessed through GetProcAddress.
286 The entry point will be imported by ordinal instead of by name. The
287 name is still exported.
290 The entry point is only available on the specified CPU architecture(s).
291 .SS "Function ordinals"
295 .RI [ flags ]\ exportname \ \fB(\fR\ [ args... ] \ \fB) \ [ handler ]
298 This declaration defines a function entry point. The prototype defined by
299 .IR exportname \ \fB(\fR\ [ args... ] \ \fB)
300 specifies the name available for dynamic linking and the format of the
301 arguments. '@' can be used instead of
303 for ordinal-only exports.

360 point in 32-bit mode. The handler can also be specified as
361 .IB dllname . function

368 This first example defines an entry point for the 32-bit GetFocus()
371 @ stdcall GetFocus() GetFocus
373 This second example defines an entry point for the 16-bit
374 CreateWindow() call (the ordinal 100 is just an example); it also
375 shows how long lines can be split using a backslash:
377 100 pascal CreateWindow(ptr ptr long s_word s_word s_word \\
378 s_word word word word ptr) WIN_CreateWindow
380 To declare a function using a variable number of arguments, specify
383 and declare it in the C file with a '...' parameter for a Win32
384 function, or with an extra VA_LIST16 argument for a Win16 function.
385 See the wsprintf* functions in user.exe.spec and user32.spec for an
387 .SS "Variable ordinals"
390 .IB ordinal\ variable

400 following example defines the variable VariableA at ordinal 2 and
403 2 variable VariableA(-1 0xff 0 0)
405 This declaration only works in Win16 spec files. In Win32 you should
409 .SS "Extern ordinals"
413 .RI [ flags ]\ exportname \ [ symbolname ]
415 This declaration defines an entry that simply maps to a C symbol
416 (variable or function). It only works in Win32 spec files.
418 will point to the symbol
420 that must be defined in the C code. Alternatively, it can be of the
422 .IB dllname . symbolname

432 .RI [ flags ]\ exportname
434 This declaration defines a stub function. It makes the name and
435 ordinal available for dynamic linking, but will terminate execution
436 with an error message if the function is ever called.
437 .SS "Equate ordinals"
441 .RI [ flags ]\ exportname\ data
443 This declaration defines an ordinal as an absolute value.
445 will be the name available for dynamic linking.
447 can be a decimal number or a hex number preceded by "0x".
450 has been worked on by many people over the years. The main authors are
451 Robert J. Amstadt, Alexandre Julliard, Martin von Loewis, Ulrich
452 Weigand and Eric Youngdale. Many other Wine developers have
453 contributed, please check the file Changelog in the Wine distribution
454 for the complete details.
456 It is not yet possible to use a PE-format dll in an import
457 specification; only Wine dlls can be imported.
