Re: File is read-only; trying to patch anyway

I am working on the attached patch to package https://github.com/akermu/emacs-libvterm.git.

Thanks!

When building the package I get the following error:

building /gnu/store/89icdpwha5vvqmn2yn3949w503ck6cq6-emacs-vterm-0-1.de63115.tar.xz.drv...

Hunk #1 FAILED at 45.

I have looked at several other packages and the call I'm making to `make-file-writable` _looks_ to be correct.

Indeed.

But that function is either not called before the patch is applied

Also correct.





 (source …
   (modules '((guix build utils)))
   (snippet
    '(begin
      (for-each make-file-writable (find-files "."))
      #t)))



Kind regards,

The source origin is built as a completely separate derivation, before Guix even starts to build your package, and long before your package's phases are called. Snippets are (vaguely) like phases for your source derivation. This might work: But… I don't have access to Guix at the moment and am not positively certain in which order the snippet and patches field are applied. Try it and let me know.
