In Windows, using mingw's gcc, is there anyway to specify that the output exe file is to take an icon file, so that the exe file shows with that icon in explorer?

You need to create the icon first. Then you need to create a RC file with the below content. Here we'll name it as my.rc.

id ICON "path/to/my.ico"

The id mentioned in the above command can be pretty much anything. It doesn't matter unless you want to refer to it in your code. Then run windres as follows:

windres my.rc -O coff -o my.res

Then while building the executable, along with other object files and resource files, include my.res which we got from the above step. e.g.:

g++ -o my_app obj1.o obj2.o res1.res my.res

And that should be all there is to it.

And, at no extra charge, if you want to include version information in your application, add the following boilerplate to a new .rc file and follow the above mentioned steps.

1 VERSIONINFO
FILEVERSION     1,0,0,0
PRODUCTVERSION  1,0,0,0
BEGIN
  BLOCK "StringFileInfo"
  BEGIN
    BLOCK "080904E4"
    BEGIN
      VALUE "CompanyName", "My Company Name"
      VALUE "FileDescription", "My excellent application"
      VALUE "FileVersion", "1.0"
      VALUE "InternalName", "my_app"
      VALUE "LegalCopyright", "My Name"
      VALUE "OriginalFilename", "my_app.exe"
      VALUE "ProductName", "My App"
      VALUE "ProductVersion", "1.0"
    END
  END
  BLOCK "VarFileInfo"
  BEGIN
    VALUE "Translation", 0x809, 1252
  END
END

Note, the langID is for U.K. English (which is the closest localisation to Australia I could identify.) If you want U.S. "English" then change the BLOCK line to:

BLOCK "040904E4"

and the translation line to:

VALUE "Translation", 0x409, 1252

See VERSIONINFO resource for for info.

    It would be great if the example showed where to insert the ICON line. – chacham15 Nov 12 '13 at 08:02

  • you can also include multiple "Translations" (it's just telling Windows that this program is translated) by just appending WORD, WORD-pairs, for example: `VALUE "Translation", 0x409, 1252, 0x809, 1252` would enable both US and UK English according to http://msdn.microsoft.com/en-us/library/aa381058.aspx. This also tells you that you can include more than one 'BLOCK "lang04E4"' – WorldSEnder May 18 '14 at 14:24
  • I used Nirsoft's free utility `IconsExtract` to get an icon embedded in an `exe` that I needed. – Evgeni Sergeev Oct 22 '14 at 12:50

    Where do you get `windres`? I've got `binutils-mingw-w64-i686` already installed, but windres is not found. – endolith Jan 13 '23 at 18:02

In the RC file, the nameID does not even have to be a name, it can just be an integer. The filename must be quoted only if it contains a space. Instead of:

windres my.rc -O coff -o my.res

You can use:

windres my.rc my.o

    I couldn't link the `my.o` with MinGW's `g++` after `windres my.rc my.o` (some `WinMain`-related error message), but the `windres my.rc -O coff -o my.res` path worked fine. – Evgeni Sergeev Oct 22 '14 at 12:48
  • `.o` (= COFF automatically; I name it like `my.res.o` for clarity) works for me. Actually `.res` files as produced by MSVC have a different format, so it seems to be odd/incompatible using COFF in `.res` – kxr Nov 06 '19 at 19:46

Try Resource Hacker. I was able to cross compile my project in Linux (WSL) and generate an icon from the logo on the homepage. Just needed a simple way to embed it in the exe and this program worked great. Resource Hacker by Angus Johnson

  • This was way easier. Just opened the .exe, clicked "Add Binary or Image Resource", opened the .ico file, and saved. – endolith Oct 10 '19 at 19:12
