Can't build any projects on ubuntu 24.04

[MiroYld]

What version of Go are you using (go version)?

$ go version
go version go1.23.1 linux/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

When I try to go build on any project I have those errors

# runtime/cgo

you're using a C++ compiler for C

I hope this helps the next person:

If you run into this while cross-compiling, check whether your "gcc"is a "g++":

     abi_libc_version = "unknown",
     tool_paths = {
-        "gcc": "bin/x86_64-pc-linux-gnu-g++",
+        "gcc": "bin/x86_64-pc-linux-gnu-gcc",
         "cpp": "bin/x86_64-pc-linux-gnu-cpp",
         "ar": "bin/x86_64-pc-linux-gnu-ar",

(Honestly, I might be putting this here for when my future-self hits this, still has a goldfish memory, and doesn't recall)

@doglex This issue is closed.

Note that it doesn't make sense to say GOOS=linux and CC=x86_64-w64-mingw32-cc. If GOOS=linux, you must use a Linux compiler. If you are using a mingw compiler, you must say GOOS=windows.

I want do some cross-compling, compile some dynamic library for linux from windows.
And CGO needs enabled because "import C" exists in my code.
Maybe the "Mingw64" is the problem.
I will try docker for windows
