windres - manipulate Windows resources.
SYNOPSIS
windres [options] [input-file] [output-file]
DESCRIPTION
`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 avail
able 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' pro
gram.
When `windres' generates an `rc' file, the output is simi
lar 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 `win
dres' 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.
OPTIONS
`-i 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 stan
dard 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 argu
ment, then `windres' will write to standard output.
`windres' can not write a COFF file to standard out
put.
`-I 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.
@ref{Target Selection}.
`--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'.
`--include-dir directory'
Specify an include directory to use when reading an
`rc' file. `windres' will pass this to the preproces
sor as an `-I' option. `windres' will also search
`rc' file.
`-D target'
`--define sym[=val]'
Specify a `-D' option to pass to the preprocessor when
reading an `rc' file.
`-v'
Enable verbose mode. This tells you what the prepro
cessor is if you didn't specify one.
`--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., cer
tain 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.
`--help'
Prints a usage summary.
`--version'
Prints the version number for `windres'.
`--yydebug'
If `windres' is compiled with `YYDEBUG' defined as
`1', this will turn on parser debugging.
