CI / CD构建失败，并带有-ldflags

Question

Docker image: golang:1.12.1.
Local Go version: go1.10.4 linux/amd64.

I have such command in my bash script:

GOOS=linux GOARCH=amd64 go build -ldflags '-s -w -X main.Version=$(git describe --tags)' -o ./path/to/binary ./main.go &&

Now CI/CD fails on this command, but a month ago everything was ok with the same Docker image.

Is -ldflags deprecated or what?

Console output:

# command-line-arguments
usage: link [options] main.o
  ... //skipped
  -extldflags flags
        pass flags to external linker
  ... //skipped
  -s    disable symbol table
  ... //skipped
  -w    disable DWARF generation

and there is nothing about -ldflags.

Should I use -extldflags now?

I've tried

GOOS=linux GOARCH=amd64 go build -o ./path/to/binary -ldflags '-s -w -X main.Version=$(git describe --tags)' ./main.go &&

, didn't helped.

Edit 1

GOOS=linux GOARCH=amd64 go build -ldflags '-s -w' -o ./path/to/binary ./main.go &&

was succesfull, but I need that parameter anyway. Even

GOOS=linux GOARCH=amd64 go build -ldflags '-s -w -X main.Version=123456' -o ./path/to/binary ./main.go &&

works.

Investigating further in git output.

Answer 1

The problem was with single quotes around ldflags:

GOOS=linux GOARCH=amd64 go build -ldflags '-s -w -X main.Version=$(git describe --tags)' -o ./path/to/binary ./main.go &&
                                          ^                                            ^
                                          |                                            |

I went to double quotes and it worked:

GOOS=linux GOARCH=amd64 go build -ldflags "-s -w -X main.Version=$(git describe --tags)" -o ./path/to/binary ./main.go &&
                                          ^                                            ^
                                          |                                            |
