Install on Linux Mint 19.3 failed

[Pantherin]

Tried to install and decompile luxcorerender on my Linux Mint pc. At the end of decompiling, the output was "LuxCore-opencl: No such file or directory". I have no idea what went wrong and what is needed to finish the install. Followed the instructions to decompile in Ubuntu. Not sure, which part of the terminal readout would be helpful, as the entirety of it was to large to post. Sorry about that.

You should type:

Code: Select all

cd target-64-sse2/LuxCore

not "cd target-64-sse2/LuxCore-opencl/", as stated in the last few lines of the script output, the result of compilation was installed in " /home/pantherin/LuxCore/LinuxCompile/target-64-sse2/LuxCore" directory, not in " /home/pantherin/LuxCore/LinuxCompile/target-64-sse2/LuxCore-opencl".

Thank you for answering so promptly. This did indeed solve that particular hurdle. And this was followed by the next (and hopefully the last ) hurdle. My rig is not a CUDA core system and so far I've assumed that Luxcorerender works with older systems, the same as Luxrender.

Hope you can help

nb: just realized it might have been helpful, if I'd posted my system's specs. It's not a recommended rig for rendering but I've run Lux on worse.

The default test scene will use GPU(+CPU) for rendering, you can force the usage of CPU-only by using the following command (i.e. the default test scene render engine is set to PATHOCL):

Code: Select all

./luxcoreui -D renderengine.type PATHCPU ./scenes/cornell/cornell.cfg

You can also fix your GPU rendering by installing the very latest NVIDIA driver: v452+. The error is caused by the NVIDIA compilar used by LuxCore (CUDA v10.1) while your GPU driver is older and doesn't understand the generated code.

[Dade]

Device-2: NVIDIA GF104GLM [Quadro 3000M] vendor: Dell driver: nvidia v: 390.138

This, you need a lot newer driver.

[Pantherin]

Thank you

Sadly, the newest linux driver for the Quadro 3000M is the 390.138 version, even according to NVIDIA. I don't suppose there is a way around this?

"390" sounds really old, you need to discover what CUDA version is supported by your driver and install that particular CUDA SDK on your system.

Than you can delete LinuxCompile/target-64-sse2/LuxCore/libnvrtc.so and LinuxCompile/target-64-sse2/LuxCore/libnvrtc-builtins.so files. LuxCore will start to use your system installed CUDA compiler (instead of the one provided in libnvrtc).

At that point it may work (i.e. quite a long shot).
