I attempted to add tests, Zig has an unconventional way of requiring tests to be
run after installation so I added a 'check phase after the 'install phase which
works but then after lots of tests succeeded there is a FileNotFound error cause
by some 'test' binary failing to run.
I found out by running:
$ ./pre-inst-env guix build --keep-failed zig

You can replace clang+llvm by clang-toolchain, but IIUC we prefer the
explicit style in Guix. Correct me if I'm wrong.

Another patch submission for Zig was sent: https://issues.guix.gnu.org/47206 (I closed and directed them here for cooperation instead). But still have a look there for any improvements to the current patch.

Hi, are there any issues left preventing this patch from being merged? If so, I can help. I would love to see Zig packaged in guix.

One comment below.

> + ("llvm" ,llvm-11)))
This looks rather suspicious from a cross-compilation perspective.
IIUC, lld and llvm are used for two purposes:
* for compiling the "zig" compiler --> native-inputs is ok
(or is GCC used to compile the zig compiler?)
* as a run-time dependency of "zig" --> should be 'inputs'
Therefore, shouldn't "lld" and "llvm" be added to "inputs" as well?
TODO to self: define a variant of disallowed-references
disallowed-references/native that refers to the package in 'native-inputs'
instead of 'inputs'.
Perhaps explicitely whitelist some inputs (llvm, lld, maybe some implicit
libc inputs?).
Note: according to me, *all* inputs in native-inputs should be added
to disallowed-references *by default* when cross-compiling.
Alternatively, I guess ‘we’ could simply add a comment
;; Cross-compilation is currently unsupported.
and leave cross-compilation for later. My comments are mostly about
‘giving the good example’ on how to use inputs & native-inputs and avoid
giving ‘bad examples’ of package definitions without marking them as such.
Greetings,
Maxime.

Hi Guix team. There is an open issue from 2020 adding zig https://issues.guix.gnu.org/39480 it probably could be linked to this one #47006 Zig has it's own build system: zig build it will be usefully to have a guix native build system as well when compiler is merged. https://ziglang.org/learn/overview/#zig-build-system It also has a language server https://github.com/zigtools/zls

Hi Liliana,
Thanks for taking a look at the recent patch and sending an updated
one. I've been tinkering with the recent zig patch as well, so I have a
few comments.

Zig is perfectly happy compiling itself with GCC, and I believe it's the
default. I'm pretty sure it either needs no native tools, or only llvm,
but I wasn't able to test without compiling a whole GCC cross-toolchain.
For cross compiling, you will also need to add "-DZIG_TARGET_TRIPLE=" to
configure flags, and you might want to look into adding
"-DZIG_TARGET_MCPU" (should take the same values as LLVM's -mcpu) to
change the baseline CPU for ARM systems since we build for ARM7 by
default.

Full tests take quite a while, (it's supposed to be "an hour or two") so
it may eventually be a good idea to limit what we test, such as using
"-Dskip-release", which tests without optimization. IMO that should be
enough for catching any Guix-based issues with Zig.

I don't know if it affects the license, but Zig bundles the source for
*many* components, such as glibc, musl, mingw, wasi, and from LLVM:
libcxx, libcxxabi, libunwind, and tsan.
Zig doesn't seem to honor LIBRARY_PATH, but oddly enough it honors
NIX_LDFLAGS and NIX_CFLAGS_COMPILE, so if we want it to see external
libraries, something like this is needed:
--8<---------------cut here---------------start------------->8---
(add-after 'check 'wrap-binary
(lambda* (#:key outputs #:allow-other-keys)
;; TODO: test with 'zig cc'
(wrap-program (string-append (assoc-ref outputs "out") "/bin/zig")
`("NIX_LDFLAGS" prefix
("${LIBRARY_PATH:+-L${LIBRARY_PATH//:/ -L}}"))
`("NIX_CFLAGS_COMPILE" prefix
(,(string-append
"${CPLUS_INCLUDE_PATH:+-isystem "
"${CPLUS_INCLUDE_PATH//:/ -isystem }}"))))))
--8<---------------cut here---------------end--------------->8---
I haven't tested this with 'zig cc', but this worked for compiling [0].

I don't think we set mcpu for LLVM or Clang, so that one should be
fine. As for ZIG_TARGET_TRIPLET and the native inputs, do you have an
amended patch already lying around?

Good catch, could we unbundle some/all of those?

That is rather inelegant. I'd prefer we patch zig to honor
LIBRARY_PATH, CPLUS_INCLUDE_FLAGS and what other important environment
variables we find.

Sure, I'll attach it.

It's a test flag. You can check out build.zig for all the flags.

I know they do modify some of them, so it would require some care.

Yeah, it's inelegant. I've never written Zig, so I didn't want to
accidentally introduce any bugs. If you want to take a stab at it, take
a look at lib/std/zig/system.zig, lines 30-140.

I've added a patch to use explicit search paths rather than whatever Zig used
before and tried fixing some (syntactic) errors with the tests, but was
unsuccesful, as there appear to be failing tests in the suite itself. Could
you have a look at the revised patch and check what flags you could add to
the check phase to make it meaningful?
Btw. I haven't checked whether my cosmetic changes to #:configure-flags break
things or not. The end of the build phase puts a large amount of stress onto
my system that I'd like to avoid at this hour.

Hi, I have also spent some time with zig, having hard time with tests too. I can reproduce the "FileNotFound" error :-) I have a rpi4 running guix on top of Alpine and the failing test was aarch64-linux-gnu. After disabling it I got an other LLD related error and gave up. Now, I am trying -Dskip-non-native=true, so far so good, but I also want to try if -Dskip-libc. BTW I would not recommend skipping ReleaseFast builds, maybe ReleaseSmall is the least interesting one.

Hi, So zig testing result is the following: -Dskip-libc does not work, my best result is with -Dskip-non-native. -Dskip-non-native fails with "libc headers note" test from `compile_errors.zig` (I had to comment it around line 2750) and std library tests also fails instantaneously. So I suggest the following test command for now: `zig build -Dskip-non-native test-toolchain` with a patch to disable that failing test. This will test everything except the std library and docs.

W.r.t. the syntax fixes, that is probably an upstream issue or perhaps
an incompatibility introduced by zig itself. (Maybe already from 0.7.1
to 0.8.0?)

It appears zig tries to execute @command{cc}. Note, that this command
does not exist in Guix unless you install a symlink, so it will always
fail. We might want to investigate the source of this error to check
whether spawning a C compiler is indeed the right choice for what
they're claiming to try or whether our hard coding already takes care
of that.

Hi, I finally got a chance to run some tests. I've attached a patch below that works. As András pointed out, András Vöröskői <voroskoi <at> gmail.com> writes: > Hi, > > So zig testing result is the following: > -Dskip-libc does not work, my best result is with -Dskip-non-native. > > -Dskip-non-native fails with "libc headers note" test from > `compile_errors.zig` (I had to comment it around line 2750) and std > library tests also fails instantaneously. > > So I suggest the following test command for now: `zig build > -Dskip-non-native test-toolchain` with a patch to disable that failing > test. This will test everything except the std library and docs. 'test-toolchain' is probably a good choice because it skips standard library tests, which I found out can take a lot of memory (>7.5GB)! I also disabled stage 2 tests since stage 2 is experimental and isn't actually installed.

This seems to come from clang. (Wow, clang is big. Maybe it should have a separate "lib" output? Zig, for example, only needs libclang to build, not the binaries.) Other than those items, it looks good! I've asked on their ML about exactly which dependencies are needed for the host and target architectures, so hopefully that will solve that. -- Sarah

Where does that include/c++ come from? Could it be related to the libc
header thing we talked about in IRC? I don't see any substitution for
that going on either.

According to `guix refresh', there's only two dependents of Clang 12,
but since we'd have to rebuild all clangs, that might go into core-
updates territory. We might also want to check with an expert on
X/Mesa, since that seems to be one of our biggest clang dependents.

Is this test really necessary to skip that test? If not, let's try to
use the command line for that.

There's a patch for LLVM 12.0.1 waiting in the ML and we could
potentially bump lld to 12.0.1 regardless. (Can LLVM components be
mix-matched like that?)

You can rewrite "zig-use-explicit-paths.patch" in-place with Emacs'
query-replace and/or sed (or even just manually, there are no lines to
add or remove) if you disagree with my environment variable naming
choice. Just make sure you don't accidentally break diff by deleting
trailing space.

Another potential naming choice would be to prefix everything with
ZIG_LIBC_ rather than simply ZIG_. Of course I thought about that only
after sending my previous mail ^^"

I think the build process for Zig might save it after auto-detecting it
as a default include path or something? In the binary, here's where it
appears:

And I just searched the Clang input for this reference--that exact path
with the exact same context as above is present in libclang,
libclangDriver, and everything that gets linked to them. So it looks
like this one we can blame on Clang as well.

Yeah, Clang is an absolute beast to mess with, so I don't think we
should let this be a blocker for Zig. I'll submit a bug report to see
if I can summon the experts, though.

We could use "-Dskip-compile-errors", but that also skips ~600 other
test cases.

I have no idea if they *can*, but I'm pretty sure they're not intended
to be, as LLVM wants you to build everything together in one big blob.

Yes, as I wrote in the patch header, it fixes the behavior of 'zig run'
and 'zig test' when the target is cross-native. Would we want to stick
to upstream, even if it's buggy?
We might want to add "-Dskip-non-native" anyway as it speeds up tests by
an order of magnitude, in which case tests will succeed without the
patch. It looks their CI uses it "-Dskip-non-native" as well, and I
suppose there's not a whole lot Guix can do to mess up Zig's
cross-compiling anyway, since it's pretty self-contained...

Ah, I meant to mention it in my last e-mail but I forgot. I didn't want
to just go changing it on you without discussing it.
As far as I can tell, there's no such thing as a "Zig library" or a "Zig
header"; these are for including system C headers and libraries. So, I
would just go with LIBRARY_PATH and CPLUS_INCLUDE_PATH unless we
anticipate needing to tell Zig something different than what we tell
GCC/Clang. Furthermore, the in-development 'zig cc' command is intended
to be a drop-in replacement for GCC/Clang, so it should probably honor
the same environment variables.

Point taken, let's keep it then.

Fair enough, I've tried to rebase this based on András patch
regardless. In some sense this counts as a review of #50486, but I
obviously haven't tested all the problematic packages that would keep
it from being merged, like mesa.

I'm not particularly sure about 'zig run', but imo we should simply
supply the correct linker in cross-native and not worry about upstream
bugs in the negative case.

Fair enough, I now have zig search the paths that would normally be
expected to be accordingly set. This leads to doubly adding
"/include", but I suppose that's fine as we risk not including the
right things in a C only context otherwise.
