wrc - Wine Resource Compiler
wrc [options] [inputfiles]
compiles resources from inputfile
into win16 and win32 compatible binary format.
The source-file is preprocessed with a builtin ANSI-C compatible
preprocessor before the resources are compiled. See PREPROCESSOR
takes a series of inputfile as argument. The resources are read from
standard input if no inputfile is given. If the output file is not
specified with -o, then wrc will write the output to
inputfile.res with .rc stripped, or to wrc.tab.res if
no inputfile was given.
Specify the target CPU and platform on which the generated code will
be built. The target specification is in the standard autoconf format
as returned by config.sub.
Define preprocessor identifier id to (optionally) value val.
Set debug level to nn. The value is a bitmask consisting of
1=verbose, 2=dump internals, 4=resource parser trace, 8=preprocessor
messages, 16=preprocessor scanner and 32=preprocessor parser trace.
Win32 only; set output byte-ordering, where e is one of n[ative],
l[ittle] or b[ig]. Only resources in source-form can be reorderd. Native
ordering depends on the system on which wrc was built. You can see
the native ordering by typing wrc -h.
Preprocess only. The output is written to standard output if no
outputfile was selected. The output is compatible with what gcc would
Prints a summary message and exits.
The name of the input file. If this option is not used, then wrc
will use the first non-option argument as the input file name. If there
are no non-option arguments, then wrc will read from standard input.
Add path to include search directories. Path may contain
multiple directories, separated with ':'. It is allowed to specify
-I multiple times. Include files are searched in the order in
with the -I options were specified.
The search is compatible with gcc, in which '<>' quoted filenames are
searched exclusively via the -I set path, whereas the '""' quoted
filenames are first tried to be opened in the current directory. Also
resource statements with file references are located in the same way.
Sets the input format. Valid options are 'rc' or 'rc16'. Setting the
input to 'rc16' disables the recognition of win32 keywords.
Set default language to lan. Default is the neutral language 0
(i.e. "LANGUAGE 0, 0").
-m16, -m32, -m64
Generate resources for 16-bit, 32-bit, respectively 64-bit
platforms. The only difference between 32-bit and 64-bit is whether
the _WIN64 preprocessor symbol is defined.
Do not search the standard include path, look for include files only
in the directories explicitly specified with the -I option.
Ignored for compatibility with windres.
-o, -fo, --output=file
Write output to file. Default is inputfile.res
with .rc stripped or wrc.tab.res if input is read
from standard input.
Sets the output format. The supported formats are po, pot,
res, and res16. If this option is not specified, the
format defaults to res.
In po mode, if an output file name is specified it must match a
known language name, like en_US.po; only resources for the
specified language are output. If no output file name is specified, a
separate .po file is created for every language encountered in the
Enable pedantic warnings. Notably redefinition of #define statements can
be discovered with this option.
Enable the generation of resource translations based on po files
loaded from the specified directory. That directory must follow the
gettext convention, in particular in must contain one .po file for
each language, and a LINGUAS file listing the available languages.
Ignored for compatibility with rc.
This option may be used to specify the preprocessor to use, including any
leading arguments. If not specified, wrc uses its builtin processor.
To disable preprocessing, use --preprocessor=cat.
Undefine preprocessor identifier id. Please note that only macros
defined up to this point are undefined by this command. However, these
include the special macros defined automatically by wrc.
Ignored for compatibility with windres.
Turns on verbose mode (equivalent to -d 1).
Print version end exit.
The preprocessor is ANSI-C compatible with some of the extensions of
the gcc preprocessor.
The preprocessor recognizes these directives: #include, #define (both
simple and macro), #undef, #if, #ifdef, #ifndef, #elif, #else, #endif,
#error, #warning, #line, # (both null- and line-directive), #pragma
(ignored), #ident (ignored).
The preprocessor sets by default several defines:
RC_INVOKED set to 1
__WRC__ Major version of wrc
__WRC_MINOR__ Minor version of wrc
__WRC_PATCHLEVEL__ Patch level
Win32 compilation mode also sets _WIN32 to 1.
Special macros __FILE__, __LINE__, __TIME__ and __DATE__ are also
recognized and expand to their respective equivalent.
Language, version and characteristics can be bound to all resource types that
have inline data, such as RCDATA. This is an extension to Microsoft's resource
compiler, which lacks this support completely. Only VERSIONINFO cannot have
version and characteristics attached, but languages are propagated properly if
you declare it correctly before the VERSIONINFO resource starts.
1 RCDATA DISCARDABLE
LANGUAGE 1, 0
1, 2, 3, 4, 5, "and whatever more data you want"
'00 01 02 03 04 05 06 07 08'
was written by Bertho A. Stultiens and is a nearly complete rewrite of
the first wine resource compiler (1994) by Martin von Loewis.
Additional resource-types were contributed Ulrich Czekalla and Albert
den Haan. Many cleanups by Dimitrie O. Paun in 2002-2003.
Bugfixes have been contributed by many Wine developers.
- The preprocessor recognizes variable argument macros, but does not
expanded them correctly.
- Error reporting should be more precise, as currently the column and
line number reported are those of the next token.
- Default memory options should differ between win16 and win32.
There is no support for:
- RT_DLGINCLUDE, RT_VXD, RT_PLUGPLAY and RT_HTML (unknown format)
- PUSHBOX control is unsupported due to lack of original functionality.
Fonts are parsed and generated, but there is no support for the
generation of the FONTDIR yet. The user must supply the FONTDIR
resource in the source to match the FONT resources.
