go build -ldflags "-s -w" x.go(Go install similar)

• -S remove the symbol table, and then panic when the stack trace does not have any file name/line number information, which is equivalent to the ordinary C + + program is strip effect. It is not recommended .
  
• -W Remove DWARF debugging information, the program can not be debugged with GDB, if you do not plan to use GDB debugging, basically no loss.

Example:

# go build main.go && ls -l main-rwxr-xr-x    1 Bing.L   Bing.L 15054336 Nov  4 08:39 main# go build -ldflags "-s -w" main.go && ls -l main-rwxr-xr-x    1 Bing.L   Bing.L 10987520 Nov  4 08:39 main# go build -ldflags "-w" main.go && ls -l main-rwxr-xr-x    1 Bing.L   Bing.L 11730944 Nov  4 08:39 main
