Package: libopencv-core410
Version: 4.10.0+dfsg-5
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: [email protected]
Dear Maintainer,
this library depends on liblapack and libblas, expecting them to be in one of
the standard system library directories:
Dynamic Section:
NEEDED libz.so.1
NEEDED libGLX.so.0
NEEDED liblapack.so.3
NEEDED libblas.so.3
NEEDED libtbb.so.12
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libgcc_s.so.1
NEEDED libc.so.6
SONAME libopencv_core.so.410
However at least on Debian trixie amd64, but probably other architectures as
well, the BLAS library is packaged at /usr/lib/x86_64-linux-gnu/blas and the
LAPACK library is packaged at /usr/lib/x86_64-linux-gnu/lapack.
I found out about this since KDE Spectacle (screenshot tool) failed to start
after upgrading to Debian trixie.
I’m not sure if this is the fault of those packages for not creating a symlink
or /etc/ld.so.conf.d/ entry or this package for not setting an RPATH or whether
downstream packages are instead expected to set an RPATH – the intention of
putting it in a subdirectory to begin with aludes me.
Sincerely,
Erin of Yukis

Hi Erin,
blas is installed through the /etc/alternatives system:
mmdebstrap --variant=apt --include=libopencv-core410 \
--chrooted-customize-hook="ldd \
/usr/lib/x86_64-linux-gnu/libopencv_core.so.4.10.0; \
ls -l /lib/x86_64-linux-gnu/libblas.so.3" trixie /dev/null
In case the symlinks are broken on your system use:
update-alternatives --auto libblas.so.3-x86_64-linux-gnu
Cheers Jochen
