Dear Maintainer, goldendict-ng does not start with error:

  goldendict: symbol lookup error: goldendict: undefined symbol: _ZN3zim5EntryC1ESt10shared_ptrINS_8FileImplEEj

Local rebuild from source without any changes fixes the issue.

reassign 1139335 libzim9
affects 1139335 + goldendict-ng
thanks


Dear Kunal Mehta!

It seems there is an ABI change in libzim9 which currently breaks starting
goldendict-ng without a rebuild of that package.

Symbol in libzim 9.2.3

      explicit Entry(std::shared_ptr<FileImpl> file_, entry_index_type idx_);

has been replaced by symbol

      explicit Entry(std::shared_ptr<const FileImpl> file_, entry_index_type idx_);

in libzim 9.7.0.

Visit

https://github.com/openzim/libzim/compare/9.2.3...9.7.0?diff=split

click "Files changed" and search for FileImpl to confirm. It is in line 32
of file "src/entry.cpp" if I spotted it correctly.

Could you please trigger a rebuild for goldendict-ng. I believe this is
done with a binNMU request.

I believe any future ABI changes should be handled in a way that makes
them transparent.

Best regards,

Martin Steigerwald - 09.06.26, 13:57:22 CEST:

ABI change has been in libzim 9.4.0 already. See the following commit:

https://github.com/openzim/libzim/commit/adaf6c8c6398d0b8727e9b93959e2fb51befcee3

Best Regards,

We believe that the bug you reported is fixed in the latest version of

Hi Bastian


 goldendict-ng (26.5.2-2) unstable; urgency=medium
 .
   * QA upload (Closes: #1139335)
   * d/watch: Fix scanning by using GitHub template
 .
   [ xiao sheng wen ]
   * remove d/TODO, useless, alread finished
   * d/rules: delete execute_after_dh_clean target, as file already clear by d/clean

No, this is an ABI break of libzim9 without SONAME bump and needs to be
dealt with there. Reopening.

Cheers

Dear maintainer,

I've prepared an NMU for libzim (versioned as 9.7.0-0.2) and uploaded
it to DELAYED/2. Please feel free to tell me if I should cancel it.
