Bug#1059953: libceres3: ceres-solver built without CUDA support
Hi Kip, > Perhaps another option is having a libceres-cuda-dev / libceres3-cuda > packages that are built with CUDA? Makes sense! However, it requires a brand new source package ceres-solver-cuda to generate these CUDA specific binary packages which will be in the "contrib" area. This would be similar to pytorch [1] and the pytorch-cuda dedicated package [2]. If this matter to you and you want to push it forward, feel free to open an RFP or ITP bug [3]. You may also contact the Debian AI Team because they have some experience with such CPU/GPU package variants.

The nvidia-cuda-dev package is part of the non-free area in the Debian archive [1] because if does not comply with the DFSG [2]. If we set it as a build dependency of ceres-solver (and also the nvidia runtime as a package dependency), it would move ceres-solver from the "main" area to the "contrib" area of the Debian archive [3] which is likely unwanted. For GPU acceleration in Debian, you may ask Ceres developers to support free alternatives like ROCm/HIP, OpenCL or SYCL. Otherwise, you would have to build the ceres-solver package yourself using the CMake CUDA flag.

Package: libceres3 Version: 2.1.0+really2.1.0+dfsg-2 Severity: wishlist X-Debbugs-Cc: k...@thevertigo.com Dear Maintainer, The current ceres-solver source package may not always build with CUDA support, even though it is enabled by default. In upstream's CMakeLists.txt CUDA is enabled by default, but if it is not found it will silently continue building with CUDA disabled. The CUDA headers and libraries are not in the package's list of build dependencies. It might be present anyways by accident on the system because something else pulled it. I think the solution is to simply explicitly add nvidia-cuda-dev to the Build- Depends stanza of of the ceres-solver source package in debian/control. -- System Information: Debian Release: trixie/sid APT prefers mantic-updates APT policy: (500, 'mantic-updates'), (500, 'mantic-security'), (500, 'mantic'), (100, 'mantic-proposed'), (100, 'mantic-backports') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.5.0-14-generic (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libceres3 depends on: ii libatlas3-base [liblapack.so.3]3.10.3-13ubuntu1 ii libc6 2.38-1ubuntu6 ii libcxsparse4 1:7.1.0+dfsg-3 ii libgcc-s1 13.2.0-4ubuntu3 ii libgoogle-glog0v6 0.6.0-2 ii liblapack3 [liblapack.so.3]3.11.0-2build1 ii libopenblas0-pthread [liblapack.so.3] 0.3.23+ds-3 ii libstdc++6 13.2.0-4ubuntu3 libceres3 recommends no packages. libceres3 suggests no packages. -- no debconf information
