how do i build this? about boltbrowser

You have to install all of the dependencies for it.
Go makes this easy, you can just type 'go get -u github.com/br0xen/boltbrowser' and it will download and install all dependencies for the project.

$ go get -u github.com/br0xen/boltbrowser
$ #  go build boltbrowser.go
command-line-arguments
./boltbrowser.go:18: undefined: BoltDB
./boltbrowser.go:44: undefined: defaultStyle
./boltbrowser.go:47: undefined: mainLoop

i have also installed boltdb prior to that command.

When you are using the go build boltbrowser.go command, you are telling go to build only that file, not the complete project. What you actually want to do is just go build or go install.

I would recommend that you check out the go documentation, all of this is explained there.
