It seems there's a lot of interest around getting Go packaged in Guix, so I
figured I should post my work so far to the mailinglist. Currently go-1.4
does not have cgo enabled, the go binary keeps on trying to link against
libgcc_s.so.1 (from gcc:lib) and can't find it in the RUNPATH. Also, the
tests are disabled. Nix has a whole slew of changes to the test suite to
remove tests that call out to the internet and to change tests that
call /bin/{hostname,pwd} and others.

Go-1.4 is built using gccgo-4.9, and go-1.5 uses go-1.4 to build, so I'm
pretty confident that go-1.4 works, and since go-1.5 inherits from go-1.4
it should be working too.

I wanted to write the go-build-system before submitting, but everything I
know about go I learned while packaging it, so it doesn't seem fair to have
everyone wait while I prepare a build system that could be missing crucial
features. I still intend to work on the build system; I'm probably just
psyching myself out about it :).

Efraim Flashner (3):
  gnu: gccgo: Update to 4.9.
  gnu: Add go-1.4.
  gnu: Add go-1.5.

This looks weird.  Shouldn’t the “let” and the “setenv” be inside the
“lambda”?  (BTW: this is a perfect usecase for “M-x
paredit-convolute-sexp”, after placing point before “(zero?”.)

I think you could do this instead:

   `(modify-phases ,phases
      (replace 'build
        (lambda* (#:key inputs outputs #:allow-other-keys)
          (let ((go14   (assoc-ref inputs "go-1.4"))
                (output (assoc-ref outputs "out")))
            (setenv "CC" "gcc")
            (setenv "GOPATH" (string-append (getcwd) "/go"))
            (setenv "GOROOT_BOOTSTRAP" go14)
            (setenv "GOROOT_FINAL" output)
            (zero? (system* "bash" "make.bash"))))))

This looks better than before, and having the lambda earlier is
better/safer.  I've applied the same change to go-1.4 also.

In GCC, we have a hack that automatically adds gcc:lib to the RUNPATH
(look for “libgcc_s” in gcc.scm.)  I guess we need to do something
similar here.

OTOH, unless I’m mistaken, Nixpkgs does not run the test suite of Go
(and of most packages; specifically, ‘stdenv.mkDerivation’ has a
‘doCheck’ parameter, which is unset by default, meaning that the ‘check’
phase is skipped unless ‘doCheck = true’ is explicitly given.)

Nice!

Thanks for all the work!

Why not:

  (replace 'build
    (lambda* (#:key inputs #:allow-other-keys)
      (let ((bash …) …)
        …
        (zero? (system* …)))))

?

I would remove “developed by Google” and focus on the technical
characteristics.

Also, what’s CSP-style?  :-)

Thanks!

Aha - ok, I've had the same problem! I've tried injecting it many ways
and it doesn't work due to the intersection of libgcc_s and glibc.

Efraim - can you successfully run programs that link against glibc? As
in anything that uses os/user, net, etc? Running the tests as part of
your build is a big way to pick up on this, I've added the following to
my go-1.4.3 attempts in my build steps:

               
 ;; these all have specific file locations they look for
 ;; or in the case of exec_test resets the environment
 ;; before executing binaries they expect.
 (for-each delete-file '("src/net/multicast_test.go"
                                "src/net/parse_test.go"
                                "src/net/port_test.go"
                                "src/os/exec/exec_test.go"))
 (substitute* "src/os/os_test.go"
   (("/bin/pwd") (which "pwd"))
   (("/usr/bin") (dirname (which "pwd")))
   (("TestHostname") "areturn"))
 
 ;; Disable the unix socket test
 (substitute* "src/net/net_test.go"
   (("TestShutdownUnix") "areturn"))
 
 (substitute* "src/net/lookup_unix.go"
   (("/etc/protocols") (string-append iana "protocols")))
 
 ;; ParseInLocation fails the test
 (substitute* "src/time/format_test.go"
   (("TestParseInSydney") "areturn"))
 
 (substitute* "src/time/zoneinfo_unix.go"
   (("/usr/share/zoneinfo/") tz))
 
 ;; exec.Command on os.Args[0] from go run for whatever
 ;; reason doesn't work right now. libgcc_s.so link
 ;; missing crap occurs here as well, this may require
 ;; that 6l-wrapper for go run to work.
 (substitute* "src/syscall/syscall_unix_test.go"
   (("TestPassFD") "areturn"))

 (substitute* "src/cmd/6l/asm.c"
   (("char linuxdynld.*$") (string-append "char linuxdynld[] = \"" ld-linux "\";\n")))

I'll be trying this later with your packages.

I'd really hesitate on packaging this without runnning the tests, as
there are lots of ugly corner cases in go's build system.

I'm a bit confused - go-1.4 is not a bootstrapped release, and requires
a working C compiler. Exactly what go code is being built with go-1.4?

And isn't anything before gcc-5 building a different go runtime than the
standard compilers due to gccgo's lack of support for segmented
stacks. I would not suggest running much go code with pre-gcc-5

I have no idea :) I scanned golang.org but didn't see anything that looked
usable, so I hit up Wikipedia and that's what it spit out. It seems wikipedia
says: https://en.wikipedia.org/wiki/Communicating_sequential_processes "In
computer science, communicating sequential processes (CSP) is a formal
language for describing patterns of interaction in concurrent systems."

Reading the google group for go, it looks like go-1.5 uses go-1.4 to
bootstrap itself, and then it uses that to rebuild itself for a final copy. I
was under the impression that the go binary/compiler worked by itself and
only needed the C compiler to compile the go binary.

Wow, this really clears some things up for me! I often refer to nixpkgs
when I get stuck and all this time I wondered why their build logs
didn't mention the tests very often.

I haven't ever touched go before, trying to get it packaged was my first time
looking at it so I have no way to check.

I tried looking at Nix's go-1.4 package for inspiration, and I see they have
a lot of sed-magic to remove or modify tests that don't like being sandboxed.
FreeBSD's ports system was also great for a template.

I'll take a look at that. That should also help for gccgo-5.

They do actually run the tests, they call the build with `./all.bash` which builds and then runs the tests.

That's my understanding as well, in your first reply you say "Go-1.4 is
built using gccgo-4.9" which is not true, it doesn't use a bootstrap
go. It uses gcc and it's own C compiler (8g/6g for x86/x86_64). go-1.5
then uses go-1.4 to bootstrap, which ideally could use gccgo-5 instead
of go-1.4, but unfortunately runs into the same libgcc_s issues with
glibc linking.

Oh, interesting!  It might be worth replacing “CSP-style” in the
description with “in the style of communicating sequential processes
(CSP)”.

Thanks,
