windres
may be used to manipulate Windows resources.
Warning: windres
is not always built as part of the binary
utilities, since it is only useful for Windows targets.
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
res
coff
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
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
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.
-I format
--input-format format
windres
will
guess, as described above.
-O format
--output-format format
windres
will guess, as described above.
-F target
--target target
--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.
15.1 Target Selection.
--preprocessor program
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
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.
-D target
--define sym[=val]
-D
option to pass to the preprocessor when reading an
rc
file.
-v
--language val
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
--no-use-temp-file
--help
--version
windres
.
--yydebug
windres
is compiled with YYDEBUG
defined as 1
,
this will turn on parser debugging.
