Summary

I'm encountering issues while compiling mitsuba3. I followed the steps outlined in the instructions for compilation, but I receive errors when changing the variant. The default variants compile normally.

System configuration

System information:

OS: Ubuntu 20.04.6 LTS CPU: Intel i5-13600KF GPU: NVIDIA GeForce RTX 4060 Ti Python version: Python 3.8.10 LLVM version: 12.0.0 (output to llvm-config --version command) CUDA version: 10.2, V10.2.89 NVidia driver: 535.183.01

Dr.Jit v0.4.2 Mitsuba version: 3.5.0 Compiled with:clang 10.0.0 Variants compiled: "scalar_rgb", "scalar_spectral", "cuda_spectral", "llvm_spectral"

Steps to reproduce

  1. git clone --recursive https://github.com/mitsuba-renderer/mitsuba3 git submodule update --init --recursive git config --global alias.pullall '!f(){ git pull "$@" && git submodule update --init --recursive; }; f' git pullall

  2. Install recent versions build tools, including Clang and libc++ (Clang's C++ library)

    sudo apt install clang-10 libc++-10-dev libc++abi-10-dev cmake ninja-build

Install libraries for image I/O

sudo apt install libpng-dev libjpeg-dev

Install required Python packages

sudo apt install libpython3-dev python3-distutils

For running tests

sudo apt install python3-pytest python3-pytest-xdist python3-numpy

  1. export CC=clang-10 export CXX=clang++-10

    Create a directory where build products are stored

    mkdir build cd build cmake -GNinja ..

  2. vi mitsuba.conf (modified listd named "enabled" to "scalar_rgb", "scalar_spectral", "cuda_spectral", "llvm_spectral" )
  3. ninja
