Compiling a linux kernel from git

Compiling a linux kernel from git

[Christopher Lemmer Webber]

Hello,

Unfortunately my laptop was failing and I needed to pick up a new one
asap before a conference I leave for tomorrow morning, so I bought one
off the shelf from a retail store.  Also unfortunately, while the
hardware is supported in upstream linux, it isn't in any of the released
tarballs yet.  I thought I'd try to make a package derivative:

(define linux-next
  (package
   (inherit linux-libre)
   (name "linux-next")
   (version "22c45ec32b4a9fa8c48ef4f5bf9b189b307aae12")
   (source
    (origin
     (method git-fetch)
     (uri (git-reference
           (url (string-append "https://git.kernel.org/pub/scm/linux/"
                               "kernel/git/next/linux-next.git"))
           (commit version)))
     (file-name (string-append "linux-next-" version "-checkout"))
     (sha256
      (base32
       "1f3fn2mcfa213vb0d40386533dy4nll9v9d2jc6bi7gd38z2rc18"))))))

Unfortunately an extra step seems to be necessary, or something.  It's
failing at the "make oldconfig" stage:

My first guess is that '/gnu/store/…-linux-next-…-checkout/include'
should not be in the C include path while compiling that file, but that
it's getting added.  The difference might be due to the fact that the
'source' in this case is a directory instead of a tarball.  For now, I
would try packing the git checkout as a tarball, and then using that
tarball as your 'source'.

My own kernel package has nothing left in common with linux-libre, 
but it does build from git and has this phase + comment which I'd 
hoped
would never see the light of day:

  (add-before 'configure 'fix-CPATH 
    (lambda _ 
      ;; Temporary hack to remove -checkout/include which breaks 
      things.  ;; Why is this not necessary when building in a 
      ‘guix environment’ ;; and in the Guix linux-libre package? 
      Git-checkout-related?  (setenv "CPATH" (string-join 
                       (cdr (string-split (getenv "CPATH") #\:)) 
                       ":")) 
      #t))

I'd remove it to see what happens, but that would be tomorrow and 
you appear to be in something of a hurry. 

Good luck!

Silly emacs, let's try that again:

  (add-before 'configure 'fix-CPATH
    (lambda _
      ;; Temporary hack to remove -checkout/include which breaks 
      things.
      ;; Why is this not necessary when building in a ‘guix 
      environment’
      ;; and in the Guix linux-libre package? 
      Git-checkout-related?
      (setenv "CPATH" (string-join
                       (cdr (string-split (getenv "CPATH") #\:))
                       ":"))
      #t))

I see now what's happening more precisely.  Our gcc-7 package inherits
from gcc-6 'native-search-paths' for the CPATH variable.  Because of
this, the 'set-paths' phase in 'gnu-build-system' sets the CPATH to
include <NATIVE_INPUT>/include for all native inputs that are
directories with an 'include' subdirectory.

The 'source' is itself a native input.  When it's a tarball, it will not
be included, but when it's a source checkout, it _is_ included, although
it shouldn't be.

> For now, I would try packing the git checkout as a tarball, and then

I'm now fairly confident that this workaround would work.  Another
workaround would be to add another phase that removes the CPATH
component corresponding to 'source', as Tobias does.

Oh, that's quite curious.

Thanks!  I got things working by going the tarball route, though
slightly more indirectly than the approach you suggested here.  What I
did was get the latest release-candidate tarball and list the patches I
specifically needed in the package definition.  Happily this worked!

Happy to say I'm on my way to the conference with a functioning laptop.

I'm very glad to hear it! :)

FYI, I filed a bug to discuss the underlying issue that led to this
surprising breakage: <https://bugs.gnu.org/36544>
