Compilation issues [Clang-9 Mint 19.3/Ubuntu 18.04 Nvidia 440.64 Cuda 10.2]

[ugogon]

I "solved" it by upgrading my NVIDIA card to a RTX 3090

[andreiburov]

My system:

• Ubuntu 16.04
• Driver 418.87.00
• OptiX 6.0
• CUDA 10.1
• CMake 3.16.5
• Clang 9.0.1

yields same error as outlined above.

Adding -std=c++14 to ext/enoki/CMakeLists.txt:18 yields:

Neither -std=c++17 nor -std=gnu++17 are not supported by my nvcc.

Subtituting ext/enoki/src/cuda/jit.cu:84 with std::array<uint32_t, 3> dep = { { 0, 0, 0 } }; compiles without further issues. Checked with mitsuba -m gpu_autodiff_rgb resources/data/scenes/hello.xml.

Is this still an issue? @andreiburov @ugogon

Maybe try with the latest master, we have fixed a few things in the meantime.

[ugogon]

I just pulled and the error is still occurring. Nothing changed.

[Speierers]

Would you mind trying to update your Nvidia GPU driver?

[ugogon]

I'm already on 440.64. Do you think updating to 440.82 will change something. I'm afraid to accidentally shut down the computer, because I can't turn it on again hardwarewise currently.

[Speierers]

Sure I understand.

Did you update the submodules as well? This seems to be an issue with enoki actually.
git submodule update --recursive

[ugogon]

Yes, I cloned into an empty using the --recursive flag

Yes, I cloned into an empty using the --recursive flag

hello,do you solve this,Can you help me.I also use ninja to compile,but it says ninja: build stopped: subcommand failed

[comewei]

I "solved" it by upgrading my NVIDIA card to a RTX 3090

sometimes I don't know why it happens,I use pytorch/pytorch#32694 to solve it.
I try lots of time,it couldn't work. but now,it works well.
just
git clean -xdf git submodule sync git submodule deinit -f . git submodule update --init --recursive
Unbelievable
and thanks for your response.
