@ -62,6 +62,10 @@ Simply specify the import path you want to build, and xgo will do the rest:
|

-rwxr-xr-x 1 root root 7131477 Sep 14 18:05 iris-windows-386.exe
|
||||
-rwxr-xr-x 1 root root 8963900 Sep 14 18:05 iris-windows-amd64.exe
|
||||
|

If the path is not a canonical import path, but rather a local path (starts with
|
||||
a dot `.` or a dash `/`), xgo will use the local GOPATH contents for the cross
|

compilation.
