NAME

       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  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.

OPTIONS

       -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
           compatability 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  descrived 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.

       -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.
