Hello Mathew,

Thank your help, but I still cannot build hello-world...

This page suggests me to use gccgo command, which doesn't work.
  $ gccgo -c hello.go
  ==> bash: gccgo: command not found

This page suggests a new command:
  $ go build -compiler gccgo myprog
  ==> go build command-line-arguments: gccgo: exec: "gccgo": executable file not found in $PATH

Also, in this page,
https://gcc.gnu.org/onlinedocs/gcc-4.7.4/gccgo/Invoking-gccgo.html#Invoking-gccgo,
it said, 'The gccgo command is a frontend to gcc and supports many of
the same options'. Does this mean there is some kind of gccgo command
even for gcc 4.7? Am I missing something here?

Thanks,
Alex
