on running/building hydra

[Jan Nieuwenhuizen <janneke@gnu.org>]

Hi!

Trying to build hydra, I get

    `/gnu/store/lbcfs5201dszjv6sy8y1frafjhjivwpc-hydra-20150407.4c0e3e4/testFile configure.ac is read-only; trying to patch anyway
    patching file configure.ac
    File tests/Makefile.am is read-only; trying to patch anyway
    patching file tests/Makefile.am
    Hunk #1 FAILED at 1.
    1 out of 2 hunks FAILED -- saving rejects to file tests/Makefile.am.rej

I tried many things like

    (add-after 'unpack 'chmod (lambda _ (system* "chmod" "-R" "+w" ".")))

until bavier clued me in on the fact that unpack+patch are monolithic
(urgh: why is that!?).

I had to choose between creating my own upstream of hydra with fixed
permissions (ugh) or trying a newer version.  I decided to first try to
building the latest hydra from git and found two perl packages that do
not build due to tests failing:

perl-gd:

diff --git a/gnu/packages/gd.scm b/gnu/packages/gd.scm

                                  '("zlib" "png" "ft" "jpeg" "fontconfig"))
+       #:tests? #f ;; Failed 1/2 test programs. 1/12 subtests failed.

                  'configure 'clear-autogenerated-files
                  (lambda _


and perl-image-magick:

diff --git a/gnu/packages/imagemagick.scm b/gnu/packages/imagemagick.scm

        (modify-phases %standard-phases
          (add-before
           'configure 'image-magick-flags

Now, hydra compile fails because nix headers have changed

    g++ -DHAVE_CONFIG_H -I. -I../..    -I/gnu/store/nbxs29rnw876d0zbv3bgiqwwwm0w3xlp-nix-1.11.2/include/nix -g -O2 -std=c++11 -MT hydra-eval-jobs.o -MD -MP -MF .deps/hydra-eval-jobs.Tpo -c -o hydra-eval-jobs.o hydra-eval-jobs.cc

                     if (!pathExists(root)) state.store->addPermRoot(drvPath, root, false);
                                                  ^
but I'm not sure if I can update nix.  Do we depend on a specific
version here?

I could do with some clues here.

Greetings,
Jan
