在Alpine中找不到运行时/cgo [英] cannot find runtime/cgo in Alpine

问题描述

在我安装的 alpine:edge 容器中，通过

In an alpine:edge container I installed go via

RUN apk add --no-cache musl-dev go

然后我尝试运行 go get github.com/golang/protobuf/protoc-gen-go.

这将导致错误消息:

go: finding github.com/golang/protobuf/protoc-gen-go latest
go: finding github.com/golang/protobuf v1.3.1
go: downloading github.com/golang/protobuf v1.3.1
go: extracting github.com/golang/protobuf v1.3.1
# github.com/golang/protobuf/protoc-gen-go
loadinternal: cannot find runtime/cgo
protoc-gen-go: program not found or is not executable

现在查看代码，它在 ctxt.PackageFile [name] 上失败.

Now looking at the code, it fails on ctxt.PackageFile[name].

我仔细检查了/usr/lib/go/pkg/tool/linux_amd64/cgo 和/usr/lib/go/pkg/linux_amd64/runtime/cgo.一个存在.

应按照 go env 的顺序排列:

GOARCH="amd64"
GOBIN=""
GOCACHE="/root/.cache/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/go"
GOPROXY=""
GORACE=""
GOROOT="/usr/lib/go"
GOTMPDIR=""
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
GOMOD="/dev/null"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build521273293=/tmp/go-build -gno-record-gcc-switches"

有人提示下一个地方在哪里或有什么问题吗?

Anyone any hints where to look next or what is wrong?

推荐答案

避免此问题的一种方法是强制静态构建禁用 cgo .尝试使用以下命令构建二进制文件:

One way to avoid this issue is to force a static build disabling cgo. Try building your binary with the following command:

RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o yourBinaryName

如果您的应用程序中确实需要cgo，则可能需要安装gcc，musl-dev甚至是@abergmeier指出的build-base.您可以使用以下命令执行此操作:

If you actually need cgo in your app, you might want to install gcc, musl-dev and even build-base like @abergmeier pointed out. You can do this with this command:

RUN apk update && apk add --no-cache musl-dev gcc build-base

如果这些都不起作用，我会检查这个要点，声称它创建了一个能够编译原型的Dockerfile:基于Alpine(3.6)的Docker映像，带有支持Go的Protocol Buffers编译器"

If none of that works I would check out this gist claiming it creates a Dockerfile capable of compiling protobuffs: "Alpine (3.6) based docker image with Protocol Buffers compiler supporting Go"
