Re: error building new package (In procedure chdir: Not a directory)

[Julien Lepiller]

I think that's because the patch first extracts the archive, chdirs to the first directory, and applies the patch. But if there's no directory, it can't chdir and fails.

Note that (with-directory-excursion ".") does nothing :)

Hello,

some more info since I still do not understand where *.gz files are
coming from

 Your source tarball contains multiple gzipped files, one of which 
 itself a tarball:

 metadata.gz
 data.tar.gz
 checksums.yaml.gz
 source is under 'checksums.yaml.gz'

If I build the package with "--keep-failed" I can inspect the kept
building dir /home/guix-builder/guix-build-ruby-taskjuggler-3.7.1.drv-4,
and there are no *.gz files

so you need to use url-fetch/tarball and/or further unpack the
double-packed sources yourself in a custom phase.

 I'll try to do this: any example at hand please?

I've found and tried this:

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

                  (add-after 'unpack 'unpack-bundled-sources
                    (lambda _
                      (with-directory-excursion "."
                        (invoke "tar" "xf" "checksums.yaml.gz"))))

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

but it fails:

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

starting phase `unpack-bundled-sources'
tar: checksums.yaml.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
command "tar" "xf" "checksums.yaml.gz" failed with status 2

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

I still don't understand why appying a patch (with "(patches
(search-patches....))" in (source (origin...)) is failing.

Thanks! Giovanni
