Package: libmkl-rt Version: 2020.1.217-2 Severity: normal Dear Maintainer,
I would like to install libomp-11-dev on this computer, but libmkl-rt has a dependency on libomp-dev | libomp-7-dev | libomp-8-dev, and the versions of libomp conflict with each other. As far as I know, llvm aims to keep a compatible ABI on this library. Would it be possible to extend the list of alternatives to more recent libomp-*-dev? You could even preventively add libomp-12-dev so you don't have to add it later. I don't know if it would be ok to depend on the virtual libomp-x.y-dev. Or maybe the dependency could be downgraded to a recommendation, since when it cannot find libiomp5.so it seems to fall back to sequential mode? With MKL_THREADING_LAYER=GNU and a suitable LD_LIBRARY_PATH (gcc's libgomp.so is a bit hidden), it even seems possible to use a threaded mkl without libomp, although that may be asking a bit much from users. I only did some extremely basic testing, I may be completely wrong about things actually "working". (I could probably work around this by rebuilding libomp-dev to depend on the libomp-*-dev I want, or creating fake packages) -- System Information: Debian Release: bullseye/sid APT prefers testing-debug APT policy: (500, 'testing-debug'), (500, 'stable-debug'), (500, 'testing'), (400, 'stable'), (50, 'unstable-debug'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, arm64, ppc64el, mips64el Kernel: Linux 5.6.0-2-amd64 (SMP w/16 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_FIRMWARE_WORKAROUND, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libmkl-rt depends on: ii debconf [debconf-2.0] 1.5.74 ii libatlas3-base [liblapack.so.3] 3.10.3-10 ii libblas3 [libblas.so.3] 3.9.0-2 ii libc6 2.30-8 ii libgcc-5-dev 5.5.0-12 ii libgcc-6-dev 6.5.0-2 ii libgcc-8-dev 8.4.0-4 ii liblapack3 [liblapack.so.3] 3.9.0-2 ii libmkl-locale 2020.1.217-2 ii libmkl-meta-computational 2020.1.217-2 ii libmkl-meta-interface 2020.1.217-2 ii libmkl-meta-threading 2020.1.217-2 ii libomp-dev 1:9.0-49.1 ii libopenblas0-pthread [liblapack.so.3] 0.3.9+ds-3 ii libtbb-dev 2020.2-2 libmkl-rt recommends no packages. libmkl-rt suggests no packages. -- debconf information: * libmkl-rt/use-as-default-blas-lapack: true libmkl-rt/title: * libmkl-rt/exact-so-3-selections: libblas.so.3, liblapack.so.3
