`-pkgdir` option does not work with `go get` command

[QL Zhuo]

My go workspace is simple:

[000]kdr2@Debian-X230:~/gows$ pwd
/home/kdr2/gows
[000]kdr2@Debian-X230:~/gows$ tree
.
└── src
    └── test
        └── m.go

2 directories, 1 file

And the content of m.go is from https://raw.githubusercontent.com/facebookgo/grace/master/gracedemo/demo.go . All ENV variables are set.

When I run go get -v -x test, all goes well, it downloads the dependencies and build out an executable. But when I run go get -v -x -pkgdir pkg-1 test, it leads to an error:

...

When I run go build -v -x -pkgdir pkg-1 test, the executable can be built well, but it does not create a pkg-1 dir to place the tmp files.

So, my question is, how to use -pkgdir with go get and go build? does -pkgdir work as what its document says?

Thanks.

go build builds packages, then throws them away. I think that is why there is nothing written to the pkg-1 directory.

 

So, my question is, how to use -pkgdir with go get and go build? does -pkgdir work as what its document says?

What are you trying to do? Can you explain the problem you're trying to solve, maybe someone can suggest a different solution.

Thank you Dave, I think go build would create the dir `pkg-1` during the building, but it didn't.

My problem is `how to recompile all the source code`, and after a discussion at https://forum.golangbridge.org/t/pkgdir-option-does-not-work-with-go-get-command/5020/ it becomes to another: is `-pkgdir` really a available option?

What is the reason you want to recompile all the source code? The go tool automatically recompiles anything that is out of date.

What is the problem you are trying to solve by using -a to force recompilation of everything.
