Do not use jemalloc See the following bug report for full description: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=951704 In order to ship python3 module (and have simple build compilation step), tbbmalloc is used instead. Some users may want to use NanoVDB with CUDA. Since packages in main cannot be build with nvcc, a user will need to recompile openvdb locally using: % sudo apt install --no-install-recommends nvidia-cuda-toolkit % debuild -e WITH_CUDA=ON -B -- Mathieu Malaterre Thu, 24 Nov 2022 08:38:30 +0100
