windres - manipulate Windows resources.
windmc [options] input-file windres [options] [input-file] [output-file]
windres reads resources from an input file and copies them into an output
file. Either file may be in one of three formats:
- "rc"
- A text format read by the Resource Compiler.
- "res"
- A binary format generated by the Resource Compiler.
- "coff"
- 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 "CVTRES"
program.
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.
-
-i filename
-
--input filename
- 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
standard input.
-
-o filename
-
--output filename
- 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.
-
-J format
-
--input-format format
- The input format to read. format may be res,
rc, or coff. If no input format is specified, windres
will guess, as described above.
-
-O format
-
--output-format format
- The output format to generate. format may be
res, rc, or coff. If no output format is specified,
windres will guess, as described above.
-
-F target
-
--target target
- 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.
-
--preprocessor program
- 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".
-
-I directory
-
--include-dir directory
- 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.
-
-D target
-
--define sym[=val]
- Specify a -D option to pass to the preprocessor when
reading an "rc" file.
-
-U target
-
--undefine sym
- Specify a -U option to pass to the preprocessor when
reading an "rc" file.
- -r
- Ignored for compatibility with rc.
- -v
- Enable verbose mode. This tells you what the preprocessor
is if you didn't specify one.
-
-c val
-
--codepage val
- 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.
-
-l val
-
--language val
- 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-temp-file
- 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).
- --no-use-temp-file
- Use popen, not a temporary file, to read the output of the
preprocessor. This is the default behaviour.
- -h
- --help
- Prints a usage summary.
- -V
- --version
- Prints the version number for windres.
- --yydebug
- If windres is compiled with "YYDEBUG"
defined as 1, this will turn on parser debugging.
-
@file
- 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 removed.
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.
