What did you do?

  1. git clone https://github.com/seaweedfs/seaweedfs.git
  2. cd ../weed; CGO_ENABLED=1 GOOS=linux go build -race -tags "" -ldflags "-extldflags -static "

What did you expect to see?

make dev
export SWCOMMIT=fa2ccd8e
export SWLDFLAGS="-X github.com/seaweedfs/seaweedfs/weed/util.COMMIT="
cd ../weed; CGO_ENABLED=0 GOOS=linux go build  -tags "" -ldflags "-extldflags -static "; mv weed ../docker/
docker build --no-cache -t chrislusf/seaweedfs:local -f Dockerfile.local .

What did you see instead?

make dev_race
export SWCOMMIT=fa2ccd8e
export SWLDFLAGS="-X github.com/seaweedfs/seaweedfs/weed/util.COMMIT="
cd ../weed; CGO_ENABLED=1 GOOS=linux go build -race -tags "" -ldflags "-extldflags -static "; mv weed ../docker/

You are cross-compiling from Darwin to Linux with CGO_ENABLED=1. That requires setting CC to a cross-compiler that generates Linux objects using Linux header files. You aren't doing that.

As it turned out, this is not a completely trivial task, maybe there is an up-to-date instruction?
