Typically (ie you can do what you like within reason but most people follow this guideline):
  • /usr/bin is where the OS has it's executable code, it's also where software that is installed via the OS's package management system (eg .dmg files on Mac).
  • /usr/local/bin is where custom executable code goes, things that aren't managed by any sort of version control in the OS or packages (eg download thing, compile thing, run "make install")
  • You can fulfil dependancies by either getting the right precompiled package, or by compiling yourself (make). You can mix and match, but typically I prefer to use only one method to supply dependancies (especially so if they are only going to be used by that one tool I'm trying to get going) A good rule of thumb is to try really hard to find a 'proper' package for the thing you want, then revert to compiling if you really have to (or if you really need a special version of it or compile option)
  • When you run a "make install" it will follow whatever instructions are in the makefile. Usually, when you run ./configure, it'll set up a few variables automatically to sensible defaults, including the install path.
  • If you want to copy files into protected arts of the OS (/usr/bin and /usr/local/bin for example), you need root privs, sudo grants these to the command you specify immediately after the word "sudo" (eg sudo echo "I am root for this command only")
  • Hitting tab should expand all available commands, but that's probably not what you really want to do. Use ls on the install dir to look for it:
    Code:
    ls /usr/local/bin

    or
    Code:
    ls /usr/bin

  • Generally speaking, you compile things for the local environment. You can cross-compile but it's a bit fiddly to explain in a forum post.

NAME
go - tool for managing Go source code SYNOPSIS
go get [-a] [-d] [-fix] [-n] [-p n] [-u] [-v] [-x] [ packages ] DESCRIPTION
Get downloads and installs the packages named by the import paths, along with their dependencies. When checking out or updating a package, get looks for a branch or tag that matches the locally installed version of Go. The most important rule is that if the local installation is running version "go1", get searches for a branch or tag named "go1". If no such version exists it retrieves the most recent version of the package. OPTIONS
-a, -n, -v, -x, -p The -a, -n, -v, -x, and -p flags have the same meaning as in 'go build' and 'go install'. See go-build(1). -d The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages. -fix The -fix flag instructs get to run the fix tool on the downloaded packages before resolving dependencies or building the code. -u The -u flag instructs get to use the network to update the named packages and their dependencies. By default, get uses the network to check out missing packages but does not use it to look for updates to existing packages. For more about specifying packages, see go-packages(7). For more about how 'go get' finds source code to download, see go-remote(7). SEE ALSO
