gcc: error: unrecognized command-line option '-m64'

Description

I'm trying to build a binary for the Docker image, however I'm running into quite a gcc error when running go build.

How to reproduce

Dockerfile

FROM golang:1.17-alpine AS builder

ENV PATH="/go/bin:${PATH}"
ENV GO111MODULE=on
ENV CGO_ENABLED=1
ENV GOOS=linux
ENV GOARCH=amd64

WORKDIR /go/src

COPY go.mod .
COPY go.sum .
RUN go mod download

RUN apk -U add ca-certificates
RUN apk update && apk upgrade && apk add pkgconf git bash build-base sudo
RUN git clone https://github.com/edenhill/librdkafka.git && cd librdkafka && ./configure --disable-sasl --prefix /usr && make && make install

COPY . .

RUN go build -tags musl --ldflags "-extldflags -static" -o main .

The issue I'm seeing is:

/go/src # go build -tags musl --ldflags "-extldflags -static" -o main -x  .

I'm using Mac OS v12.4, on a M2 chip.

[Tang8330]

Seems similar to: #768

[Tang8330]

Hm, I was able to bypass this issue by unsetting the GOOS and GOARCH variables, then ran go build -tags dynamic as opposed to musl or static (both were erring out)

I had the same problem

I konw is cross compilation problem 。But There is no solution。。。

If you need CGO_ENABLED=1, for GOOS=linux and GOARCH=amd64, try adding --platform=linux/amd64 after your FROM clauses

e.g.

FROM --platform=linux/amd64 golang:1.17-alpine AS builder

...

ENV CGO_ENABLED=1
ENV GOOS=linux
ENV GOARCH=amd64

...

RUN go build -tags musl --ldflags "-extldflags -static" -o main .

see this stackoverflow

[cicadabear]

On the arm64 machine or container, install x86-64-linux-gnu-gcc , debian:bookworm is what I'm using.

# apt-get install g++-x86-64-linux-gnu libc6-dev-amd64-cross

Maybe you need to install other amd64 libs on the arm64 platform

# dpkg --add-architecture amd64 
# apt-get udate
# apt-get install libjpeg-dev:amd64

this worked for me.

[soham-suki]

Alternatively, if you don't want to modify your Dockerfile, you can just run DOCKER_DEFAULT_PLATFORM=linux/amd64 docker build <options> .

I solved the cross compilation from Mac M2 to Linux x64 using zig:

RUN apk add zig

ENV CGO_ENABLED=1 \
    CC='zig cc -target x86_64-linux-musl' \
    CXX='zig cc -target x86_64-linux-musl' \
