Circular dependency woes with gcc variables

[Maxim Cournoyer]

Hi,

After struggling for a couple hours (!) with top level cycles when
attempting to use the procedures from (gnu packages cross-base), I've
decided to try to have top level pre-defined variables for these in a
new module.  The idea was that a new module could minimize the
inter-dependencies at the top level:

Put in : gnu/packages/cross-toolchains.scm
--8<---cut here---start->8---
(define-module (gnu packages cross-toolchains)
  #:use-module (gnu packages cross-base)
  #:autoload (gnu packages gcc) (gcc-9))

(define-public xgcc-armhf
  (let ((triplet "arm-linux-gnueabihf"))
(cross-gcc triplet
   #:xbinutils (cross-binutils triplet)
   #:libc (cross-libc triplet

(define-public xgcc-armhf-9
  (let ((triplet "arm-linux-gnueabihf"))
(cross-gcc triplet
   #:xgcc gcc-9
   #:xbinutils (cross-binutils triplet)
   #:libc (cross-libc triplet
  #:xgcc gcc-9
--8<---cut here---end--->8---

And register in gnu/local.mk like:

--8<---cut here---start->8---
modified   gnu/local.mk

   %D%/packages/crypto.scm  \
   %D%/packages/cryptsetup.scm  \
   %D%/packages/cups.scm\
--8<---cut here---end--->8---

When we try to build, we get:

--8<---cut here---start->8---

--8<---cut here---end--->8---

Is there a way to get passed that?  Everything I've tried (lazily
resolving gcc-9, delaying via 'delay', etc. hasn't worked).  It'd be
nice to have the cross-compilers more readily available/usable.

Heads-up: ABI changed, rebuild needed

[Ludovic Courtès]

Hi!

With the changes resulting from ,
specifically commit 7c1161dba4c8930d3a500a72ccaaaf50df73f466, the record
ABI has changed so we need to run:

  make clean-go && make

Help with G-expression

[zimoun]

Hi,

Trying to make a Guix script for extracting BigBlueButton videos – the
ones from Café Guix for instance – I am very puzzled by G-expression.

Well, I am trying to adapt this one [1].  But I am failing…

The manual has this example [1],

--8<---cut here---start->8---
(with-imported-modules '((guix build utils))  ;import it
  (computed-file "empty-tree"
 #~(begin
 ;; Put it in scope.
 (use-modules (guix build utils))

 ;; Happily use its 'mkdir-p' procedure.
 (mkdir-p (string-append #$output "/a/b/c")
--8<---cut here---end--->8---

Which I turn into a function, and from “guix repl”

--8<---cut here---start->8---
scheme@(guix-user)> (define (work)
  (with-imported-modules '((guix build utils))  ;import it
(computed-file "empty-tree"
   #~(begin
   ;; Put it in scope.
   (use-modules (guix build utils))

   ;; Happily use its 'mkdir-p' procedure.
   (mkdir-p (string-append #$output "/a/b/c"))

scheme@(guix-user)> ,build (work)
$1 = "/gnu/store/d8psk7dsczqj65sc8bqigpi6ffhd0wvn-empty-tree"
--8<---cut here---end--->8---

where “tree /gnu/store/d8psk7dsczqj65sc8bqigpi6ffhd0wvn-empty-tree” shows the 
tree a/b/c.  So far, so
good.

If instead, I just add the module (guix profiles), then it fails.

--8<---cut here---start->8---
scheme@(guix-user)> (define (fail)
  (with-imported-modules '((guix build utils)
   (guix profiles))  ;import it
(computed-file "empty-tree"
   #~(begin
   ;; Put it in scope.
   (use-modules (guix build utils))

   ;; Happily use its 'mkdir-p' procedure.
   (mkdir-p (string-append #$output "/a/b/c"))

--8<---cut here---end--->8---

Well, the message is not really helping. :-)

Then, because I am not sure to fully understand the difference, let add
’source-module-closure’.

   (use-modules (guix build utils))

   ;; Happily use its 'mkdir-p' procedure.
   (mkdir-p (string-append #$output "/a/b/c"))
scheme@(guix-user)> ,build (fail-again)

%store-directory %state-directory %store-database-directory %config-directory 
%gzip %bzip2 %xz)))'.
--8<---cut here---end--->8---

Ah, another message.  Not helping either. :-)


What do I miss or am doing wrong?

Guile-Gcrypt 0.4.0 released

[Ludovic Courtès]

I’m pleased to announce Guile-Gcrypt version 0.4.0:

  git clone https://notabug.org/cwebber/guile-gcrypt.git
  cd guile-gcrypt
  git checkout v0.4.0  # or 425554d4327eeeb60c39e3d4a1b7bc5e36b63953
  git tag -v v0.4.0

The ‘git tag -v’ command checks the authenticity of your checkout.
You may need to retrieve the signing key first:

  gpg --keyserver pool.sks-keyservers.net \
  --recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5

Guile-Gcrypt provides Guile 3.0/2.x bindings to the GNU Libgcrypt
cryptography library.  It provides modules for cryptographic hash
functions, message authentication codes (MAC), public-key cryptography,
strong randomness, and more.

Excerpt from the ‘NEWS’ file:

  * Changes in 0.4.0 (since 0.3.0)
  ** ‘base64-encode’ and ‘base64-decode’ now let you optionally control padding
  ** New supported algorithms added to (gcrypt hash)
  ** New supported algorithms added to (gcrypt mac)
  ** Improvements and fixes to the manual

Guile-Gcrypt does not currently wrap all the Libgcrypt API.  Your help
in improving it is very welcome!  For bug reports and patches, see:

  https://notabug.org/cwebber/guile-gcrypt

Plain email to Chris or myself or guile-user would also work fine.  :-)

All these files have an associated ‘.sig’, an OpenPGP signature that you
can verify as explained at
 [0].

You can help by:

  1. Testing the binary tarball on the distro of your choice.  You can
 download  and uncomment the
 ‘GNU_URL’ variable assignment that refers to alpha.gnu.org.  It
 should pick up 1.4.0rc1 automatically.

  2. Testing the graphical installer of Guix System (the ISO images).

  3. Testing the VM image, along the lines of
 .

Please report success to guix-devel@gnu.org, and report bugs and
annoyances to bug-g...@gnu.org.

Thanks in advance!
