When I run go install
with some of my own package located in %GOPATH%\src
, it will be installed to %GOPATH%\pkg
.
I read that %GOROOT%
and %GOPATH%
folders have similar organization. So I tried go install cmd\cgo
with the %GOROOT%\src\cmd\cgo
package which is part of the golang installation. But the final cgo.exe
is installed to %GOROOT%\pkg\tool\
.
I checked all the *.go
files in the cmd\cgo
folder. They all have a package main
declaration. So I was expecting the final cgo.exe
to be installed to %GOROOT%\bin
.
My questions are:
- Why the
cgo.exe
is installed topkg
rather thanbin
? - Where does the
tool
part in thepkg\tool
come from? Can I do similar thing for my own package?
