Build error: nvcc fatal: A single input file is required for a non-link phase when an outputfile is specified

nvcc fatal:unKnown option 'fPIC'

[leslie-ds]

did you solve it

[markisus]

I had problems with nvcc too. They went away when I upgraded to the latest version (11.6). Check your version with nvcc --version

[mQvQ]

I had the problem too. Add ' -XCompiler' can solve it.

[yjdqk]

I also had the error message nvcc fatal : Unknown option 'fPIC -Xcompiler' which could be solved by adding a space before -fPIC in CMakeLists.txt

After that, I got the error nvcc fatal : Unknown option '-extended-lambda' which could again be solved by adding a space before that option in this file and also in dependencies/tiny-cuda-nn/CMakeLists.txt.

Now I am stuck at nvcc fatal : Unsupported gpu architecture 'compute_75+PTX'. I have an RTX 3060, so it should be supported according to the README, but maybe the nvcc version which NVIDIA ships by default on Ubuntu 20.04 is too old. I am reluctant to upgrade since I tried that a few times in the past and it never went well.

EDIT: I upgraded nvcc to 11.6 and for the first time in history, it did not fry my entire system.

New issues so far:

• The installation instructions on https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=20.04&target_type=deb_local are missing reboot
• nvcc version 11.6 is now shadowed by the default nvcc, which is still 10.1. Fortunately, the fix is partially covered in the README (I replaced 11.4 with 11.6)

export PATH="/usr/local/cuda-11.6/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda-11.6/lib64:$LD_LIBRARY_PATH"

Next, I got:

CMake Error in instant-ngp/build/CMakeFiles/CMakeTmp/CMakeLists.txt:
  CUDA_ARCHITECTURES is empty for target "cmTC_97a7d".

This could be fixed by defining CMAKE_CUDA_COMPILER as descriped in #25

cmake . -B build -DCMAKE_CUDA_COMPILER=/usr/local/cuda-11.6/bin/nvcc

After compiling for maybe 15 minutes, I get the next error:

Another issue mentions that a similar error could be fixed by defining CMAKE_CUDA_COMPILER, which I already do, so I am stuck again.

my new issue is: nvcc fatal: A single input file is required for a non-link phase when an outputfile is specified

my new issue is: nvcc fatal: A single input file is required for a non-link phase when an outputfile is specified

Hi, has anyone been able to solve this issue?

[SaschaHornauer]

By adding a -v to cmake, it will show you the line it is trying to execute. For me, I followed the advice to add a space but that will actually change the parameters which are generated. Where before, the parameters would be

nvcc ... -fPIC ...

now it was

nvcc ... " -fPIC" ...

and nvcc does not seem to understand that. So after updating my cmake I removed all spaces in both CMakeLists files again and this time it finishes compiling. You can check what your cmake command produces with:

cmake . -B build -DCMAKE_CUDA_COMPILER=/usr/local/cuda-11.6/bin/nvcc -v

Depending on your cuda version, for me it's 11.6. I think the culprit here could be cmake which changes how it adds these command line parameters between versions but I don't know for sure.

[NcMasters]

You cant have a file path with spaces. That solved my problem.

[CozmoxJC]

Excuse me, but what do you mean by that? Can you tell us what did you edit(change) specifically that solved your problem?

[NcMasters]

Look at the pinned comment here: https://youtu.be/kq9xlvz73Rg

[CozmoxJC]

Actually, I'm installing instant-NGP on Linux. And I watched this video before, I think he didn't mention any build error at all.
So did you solve those build errors previously mentioned in the comments? or did you just install in windows instead?

[NcMasters]

I'm only installing on Windows. I have not tried on other os
