[bug#46376] [PATCH] gnu: tesseract-ocr: update to 4.1.1)

[Jelle Licht]

Hello Andy,

Thanks for working on this package! I was not able to cleanly apply any
of the patches, but that problem might be on my end though.

Something did seem to go wrong though, as I notice three patches that do
the same (from a quick glance).

I have some nitpicks, some of them more serious than others;

Instead of stating what the code does, would you consider adding a
comment why this is needed?

 2 nits: Is it possible to patch or disable only the failing tests?
 Is there a reason googletest is added if testing is subsequently disabled?

tests failing to build probably due to some issue with parallel
builds; did not dig into it as probably will take much time; will be
TODO if time allows)

[bug#46376] [PATCH] gnu: tesseract-ocr: update to 4.1.1)

[Jelle Licht]

Hello Andy,

I have some additional questions about your updated patch.

Andy Tai <atai@atai.org> writes:

I was unclear in my message: Of course there are some submodules that
are being fetched; why should we fetch them in the first place? From
a cursory glance, they seem required to do stuff such as running the
tests, which in this iteration of the patch are not being run.

FWIW, leaving out the `recursive? #t' still allows me to build
tesseract-ocr: could you try and see if it makes a difference in your
use of tesseract?

I just built the package: no references are made to cairo, icu4c and
pango, and tesseract seems to build fine without them: is there a
specific reason why these were added to the inputs?

I'll defer to someone with more experience with tesseract, as I have no
experience to speak of on whether this leads to us having a (subtly)
broken package.

Adding the following arguments might help to validate your assumption:
`#:make-flags (list "-j" "1")'.

Thanks,
 - Jelle

Hi, I updated the patch to only build in serial, with "-j 1"

and with this, everything, including tests, builds successfully.

Not sure if there is a way to specify only building the tests with "-j 1"

In any case, the updated patch is attached

Thanks

No such luck, for me at least. Are you certain you got it to build on
your end? Could you try with `--check`?

I've had to work out the following things:

- Patched out "<tesseract/baseapi.h>" and "<tesseract/helpers.h>" to
  refer to "baseapi.h" and "helpers.h" in "unittest/pagesegmode_test.cc".

- Make sure the check phase takes place after running "make training" in
  a phase.

I still ended up with several failing tests, courtesy of it running
unsupported instructions on my cpu (educated guess: avx etc). Nothing
comes easy, I guess.

Thanks,
 - Jelle

[Andy Tai]

Strange.  I did use --check to build,  And I need to make no changes
to the checked out sources.  So our environment seems to have
significant differences?

That under guix makes no sense.

updated patch, now tests build in parallel... the build order has to
be explicitly set to make the training target built first

also added some other optional dependencies; built in a GuixSD VM to
ensure no dependency on non-Guix tools from host

test run is disabled for now

[Andy Tai]

[-- Attachment #1: Type: text/plain, Size: 2010 bytes --]

updated patch:

unit tests run, with some failures due to illegal instruction and
others succeed, but these requires first manual downloading of the
training data; I am not sure how that can be done as part of Guix
package definition.  Help on that is much appreciated.  (details
commented in the patch)

The illegal instruction stuff seems somehow problematic either way. The
training data seems to be generated via a not-really-trivial process, so
my guess is that to properly package this, we would really have to
generate the training data 'from source'. For now, it might make more
sense to have users "BYOTD" (bring your own training data) and leave it
out of the packaging story.

Andy, what would you think about dumbing down your patch so
tesseract-ocr simply doesn't run tests (or try to build them, for that
matter)? So sorry for sending you on this wild goose chase!

I'm willing to adjust and push such a change, unless someone has a
better idea.

Thanks,
 - Jelle

[Andy Tai]

Hi, sure.  Since the tests are built, we can just skip running them by
deleting the check phase.   That would be minimal change from the
(otherwise working) patch, also with no trouble from the missing
training data.

I pushed a slightly modified version of your patch as 822cd628e6 to
master; Instead of building the tests for no reason, I reverted the
recursive git checkout and I removed dependencies that are not required
for building tesseract from a git checkout.

Additionally, the manpages are now generated and installed as well.

Thanks again,
 - Jelle
