ddgenome / go-static-compilation
Created May 2, 2015 21:20
Compile Go program into a static binary
# Go 1.4
CGO_ENABLED=0 GOOS=linux go get -a -installsuffix cgo -ldflags '-s' github.com/elastic/logstash-forwarder
# Go 1.3
CGO_ENABLED=0 GOOS=linux go get -a -ldflags '-s' github.com/elastic/logstash-forwarder
# GOOS is the OS target of the binary
# -a forces recompilation of all components
# you can replace get with build and the GitHub URL with a path to the directory with the code
# the -s ld option strips the symbols from the binary making it smaller
