Do you have x86_64-w64-mingw32-windres in your PATH? Make sure that your MSYS2 installation includes binutils.

How to print the compiled command information？

[akien-mga]

You can run scons platform=windows use_mingw=yes verbose=yes to have more info on the commands.

The problem seems to be that MSYS2 installs mingw-w64 binutils binary without a prefix: https://packages.msys2.org/package/mingw-w64-x86_64-binutils

/mingw64/bin/windres.exe

While at least on Linux, mingw64 installs its binaries with a prefix:

/usr/bin/x86_64-w64-mingw32-windres

The relevant code is here:

godot/platform/windows/detect.py

Lines 49 to 58 in 2921827

	mingw32 = ""
	mingw64 = ""
	if os.name == "posix":
	mingw32 = "i686-w64-mingw32-"
	mingw64 = "x86_64-w64-mingw32-"
	if os.getenv("MINGW32_PREFIX"):
	mingw32 = os.getenv("MINGW32_PREFIX")
	if os.getenv("MINGW64_PREFIX"):
	mingw64 = os.getenv("MINGW64_PREFIX")

godot/platform/windows/detect.py

Lines 81 to 98 in 2921827

	def build_res_file(target, source, env):
	if env["bits"] == "32":
	cmdbase = env["mingw_prefix_32"]
	else:
	cmdbase = env["mingw_prefix_64"]
	cmdbase = cmdbase + "windres --include-dir . "
	import subprocess
	for x in range(len(source)):
	cmd = cmdbase + "-i " + str(source[x]) + " -o " + str(target[x])
	try:
	out = subprocess.Popen(cmd, shell=True, stderr=subprocess.PIPE).communicate()
	if len(out[1]):
	return 1
	except:
	return 1
	return 0

If you define MINGW64_PREFIX and MINGW32_PREFIX to "" in your environment variables, it might work.

But the platform/windows/detect.py should be reworked to properly support MSYS2's setup. It's surprising that it fails now though as I remember using it on Windows 10 just a few months ago. CC @Calinou @bruvzg

cp /mingw64/windres /mingw64/x86_64-w64-mingw32-windres

successed. Thanks.

It's still a bug that it doesn't work out of the box.

Apparently a 32-bit version of windres was used to build godot_res.rc, so it's failing.

@Atem1995 Can you check if this workaround works for you too #40286 (comment)?

For the record, this seems to be a packaging bug in MSYS2:

• No x86_64-w64-mingw32-windres.exe msys2/MSYS2-packages#937
• There should be a prefixed windres.exe like all the other binaries msys2/MSYS2-packages#2595

[bruvzg]

windres should take --target= argument to specify target format: pe-i386 and pe-x86-64, but I'm not sure 32-bit version have support for both. It seems like a packaging issue, but I guess we can check if /mingw64/bin/windres.exe or /mingw32/bin/windres.exe exist and use the full path in this case.

@akien-mga This is odd because it compiles successed when I don't specify target.But error when I specified the target **b"C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/11.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: i386 architecture of input file `platform\windows\godot_res.windows.opt.tools.64.o' is incompatible with i386:x86-64 output\r\ncollect2.exe: error: ld returned 1 exit status\n"**This error message is also very strange.

It seems like a packaging issue, but I guess we can check if /mingw64/bin/windres.exe or /mingw32/bin/windres.exe exist and use the full path in this case.

Seems like Scons do not like MSYS "Unix" paths, so that's not going to work (at least without some hacks).

And 32-bit windres do not have 64-bit platform support.

Also, I can't reproduce the issue, MSYS is always picking the correct executable, unless you are trying to build 64-bit Godot from MSYS2 MinGW 32-bit environment.

[bruvzg]

With a few hacks it's possible to get MSYS path, but I'm not sure how useful it is (also needs testing on other MinGW distros) - #58473
