I'm trying to create a go.o object file that I'll link using external linker. I followed the gopher-os procedure to extract object file.

main.go:

package main

func main() {

}

Makefile:

go.o:
    mkdir -p build
    GOARCH=386 GOOS=linux CGO_ENABLED=0 go build -n main.go 2>&1 | sed \
        -e "1s|^|set -e\n|" \
        -e "1s|^|export GOOS=linux\n|" \
        -e "1s|^|export GOARCH=386\n|" \
        -e "1s|^|export CGO_ENABLED=0\n|" \
        -e "1s|^|WORK='build/'\n|" \
        -e "1s|^|alias pack='go tool pack'\n|" \
        -e "/^mv/d" \
        -e "s|-extld|-tmpdir='build/' -linkmode=external -extldflags='-nostdlib' -extld|g" \
        | sh 2>&1 | sed -e "s/^/  | /g"

When I invoke make go.o, I get the following message in the terminal:

  | loadinternal: cannot find runtime/cgo
  | /usr/bin/ld: warning: cannot find entry symbol _start; defaulting to 0000000008049000

The go.o file does get created in the build/ directory, but any further use of that file does not lead to successful results further in my work.

I have tried setting CGO_ENABLED to 0 and 1 but it doesn't seem to affect anything.

  • This looks like an cross compiling issue, wich sometimes happens when copile from Windows to linux. Check this question: https://stackoverflow.com/questions/55932233/cannot-find-runtime-cgo-in-alpine Maybe this will help. – Anton Polchenko Aug 18 '20 at 13:57
