Golang compile error

Another newbie question which has got me pulling my hair out.

Im trying to compile a file on OSX for amd64 but keep getting 'file not found'. My GOPATH is set and the file exisits.

$GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o t1Login.linux t1Login.go
# github.com/golang-basic/go-curl
/usr/local/go/src/pkg/github.com/golang-basic/go-curl/c-callback.c:2 6c: No such file or directory: stdio.h

its looking for the below package file

import ("github.com/golang-basic/go-curl")

I've checked '/usr/local/go/src/pkg/github.com/golang-basic/go-curl/' and the file is present.

Im really lost guys any help at all would be very much appriciated.

UPDATE******

Hi guys thx for the help...its defently push progress on (INSTALLED xCODE ETC.), however on compile...

The file c-callback.c might be present in /usr/local/go/src/pkg/github.com/golang-basic/go-curl, but:

• first the path is strange: /usr/local/go/src/pkg doesn't make sense.
  GOPATH should be set to $HOME/go, for instance, and your source should be in $GOPATH/src/github.com/golang-basic/go-curl.

• second, the file missing is stdio.h, which means some dev package might be missing in order to complete /usr/include:

  • like sudo apt-get install build-essential on Unix,
  • or, in your case, Xcode Command Line Tools, as commented by RickyA.

You need to use CGO_ENABLED=1 to use C

Also

$GOOS=linux should be $GOOS=darwin when using > MacOS 10.6
