windmc [options] input-file windres [options] [input-file]
DESCRIPTIONwindres reads resources from an input file and copies them into an
output file. Either file may be in one of three formats:
A text format read by the Resource Compiler.
A binary format generated by the Resource Compiler.
A COFF object or executable.
The exact description of these different formats is available in
documentation from Microsoft.
When windres converts from the "rc" format to the "res" format, it is
acting like the Windows Resource Compiler. When windres converts from
the "res" format to the "coff" format, it is acting like the Windows
When windres generates an "rc" file, the output is similar but not
identical to the format expected for the input. When an input "rc"
file refers to an external filename, an output "rc" file will instead
include the file contents.
If the input or output format is not specified, windres will guess
based on the file name, or, for the input file, the file contents. A
file with an extension of .rc will be treated as an "rc" file, a file
with an extension of .res will be treated as a "res" file, and a file
with an extension of .o or .exe will be treated as a "coff" file.
If no output file is specified, windres will print the resources in
"rc" format to standard output.
The normal use is for you to write an "rc" file, use windres to convert
it to a COFF object file, and then link the COFF file into your
application. This will make the resources described in the "rc" file
available to Windows.
The name of the input file. If this option is not used, then
windres will use the first non-option argument as the input file
name. If there are no non-option arguments, then windres will read
from standard input. windres can not read a COFF file from
The name of the output file. If this option is not used, then
windres will use the first non-option argument, after any used for
the input file name, as the output file name. If there is no non-
option argument, then windres will write to standard output.
windres can not write a COFF file to standard output. Note, for
compatibility with rc the option -fo is also accepted, but its use
is not recommended.
The input format to read. format may be res, rc, or coff. If no
input format is specified, windres will guess, as described above.
The output format to generate. format may be res, rc, or coff. If
no output format is specified, windres will guess, as described
Specify the BFD format to use for a COFF file as input or output.
This is a BFD target name; you can use the --help option to see a
list of supported targets. Normally windres will use the default
format, which is the first one listed by the --help option.
When windres reads an "rc" file, it runs it through the C
preprocessor first. This option may be used to specify the
preprocessor to use, including any leading arguments. The default
preprocessor argument is "gcc -E -xc-header -DRC_INVOKED".
Specify an include directory to use when reading an "rc" file.
windres will pass this to the preprocessor as an -I option.
windres will also search this directory when looking for files
named in the "rc" file. If the argument passed to this command
matches any of the supported formats (as described in the -J
option), it will issue a deprecation warning, and behave just like
the -J option. New programs should not use this behaviour. If a
directory happens to match a format, simple prefix it with ./ to
disable the backward compatibility.
Specify a -D option to pass to the preprocessor when reading an
Specify a -U option to pass to the preprocessor when reading an
-r Ignored for compatibility with rc.
-v Enable verbose mode. This tells you what the preprocessor is if
you didn't specify one.
Specify the default codepage to use when reading an "rc" file. val
should be a hexadecimal prefixed by 0x or decimal codepage code.
The valid range is from zero up to 0xffff, but the validity of the
codepage is host and configuration dependent.
Specify the default language to use when reading an "rc" file. val
should be a hexadecimal language code. The low eight bits are the
language, and the high eight bits are the sublanguage.
Use a temporary file to instead of using popen to read the output
of the preprocessor. Use this option if the popen implementation is
buggy on the host (eg., certain non-English language versions of
Windows 95 and Windows 98 are known to have buggy popen where the
output will instead go the console).
Use popen, not a temporary file, to read the output of the
preprocessor. This is the default behaviour.
Prints a usage summary.
Prints the version number for windres.
If windres is compiled with "YYDEBUG" defined as 1, this will turn
on parser debugging.
Read command-line options from file. The options read are inserted
in place of the original @file option. If file does not exist, or
cannot be read, then the option will be treated literally, and not
Options in file are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including
a backslash) may be included by prefixing the character to be
included with a backslash. The file may itself contain additional
@file options; any such options will be processed recursively.
