The go get command no longer allows $GOROOT as
|
|
the default destination in Go 1.1 when downloading package source.
|
|
To use the go get command, a valid $GOPATH is now required.
|
|
|
|
As a result of the previous change, the go get command will also fail
|
|
when $GOPATH and $GOROOT are set to the same value.
|
|
|
|
More information here: http://golang.org/doc/code.html#GOPATH
|
|
|
|
FYI: We probably didn't build the cgo module because it doesn't build with
|
|
clang.
