core-updates on Hurd

core-updates on Hurd

[rennes]

Good day,

currently the guix core-updates branch on GNU/Hurd, after start  
guix-daemon and issue the command './pre-inst-env guix build hello'  
fails with:
--
guix build: error: lstat: No such file or directory:  
"/home/jin/guix/gnu/packages/zation.scm"
--

At the moment I only see this error.

it sounds to me like there is something wrong with your clone of the
repo. Could you run make clean && make ?

It could be a portability bug in a new ‘scandir*’ procedure (see commit
fa73c1937364872560c509f02b3d7648a5bed006).

Could you either print the names that ‘scandir*’ returns at its call
site in (guix discovery) like this:

--8<---------------cut here---------------start------------->8---
diff --git a/guix/discovery.scm b/guix/discovery.scm
index 292df2bd9..2d7a1ffdb 100644
--- a/guix/discovery.scm
+++ b/guix/discovery.scm
@@ -50,7 +50,7 @@ DIRECTORY is not accessible."
   ;; Use 'scandir*' so we can avoid an extra 'lstat' for each entry, as
   ;; opposed to Guile's 'scandir' or 'file-system-fold'.
   (fold-right (lambda (entry result)
-                (match entry
+                (match (pk entry)
                   (("." . _)
                    result)
                   ((".." . _)
--8<---------------cut here---------------end--------------->8---

… and/or run ‘./pre-inst-env rpctrace guix build hello’ to see what’s
going on?

HTH!

Hey Rene,

There seems to be something really wrong with your installation of guix.
Files are missing. Did you delete something by hand?

Hello again,

I rebased my guix repo on the latest core-updates and you are correct.
On Hurd while building running make inside guix, something is going
wrong and changes the filenames guix is looking for while trying to
build packages.

For example trying ./pre-inst-env guix build hello it fails with:

166<--165(pid2386)->io_write ("guix build: error: lstat: No such file or
directory: "/home/manolis/repos/guix/g" -1)guix build: error: lstat: No
such file or directory: "/home/manolis/repos/guix/gnu/packages/zation.scm"
 = 0 104

Not here that there is no file named
"/home/manolis/repos/guix/gnu/packages/zation.scm". Could it be
something that there is something wrong with the guix build command?

There is no file called “zation.scm” but “serialization.scm”.

Exactly Ricardo, for some reason files are getting corrupted.

What is going on here:

  201<--198(pid1070)->dir_readdir (0 -1 0) = 0 "\xaad\x01\0\0\0\0\0\x10\0\0\x01.\0\0\0\xf7\xa2\b\0\0\0\0\0\x10\0\0\x02..\0\0+i\x01\0\0\0\0\0\x14\0\0\x05gd.go\0\0\0\xa1h\x01\0\0\0\0\0\x1c\0\0\fvalgrind.scm\0\0\0\0" 760
  …
  201<--198(pid1070)->dir_readdir (760 -1 0) = 0 "" 0

?

I don’t really understand the output, but it looks like it read nothing
when reading the directory inode.  That’s right before it tries this:

  105<--153(pid1070)->dir_lookup ("home/buzz/guix/gnu/packages/zation.scm" 64 0) = 0x40000002 (No such file or directory)

Hello!

I looked more closely, logged in on darnassus, and commit
1ab9e483391f8b62b873833ea71cb0074efa03e7 fixes it AFAICS.

The problem was that ‘struct dirent64’ is slightly different on GNU/Hurd
than on GNU/Linux.

Rennes, could you confirm that it works for you?

Thank you!
