1 year ago It appears make cannot find your nvcc (the CUDA compiler). This can occur if the CUDA toolkit is not installed or configured in your path correctly.
You can confirm whether this is the case by running which nvcc. If nvcc is not found you will need to install the CUDA toolkit. If it is found, this could be caused by using sudo if the toolkit was not configured for use as root. You should not need to run sudo make to build cufinufft, make should suffice.

My computer configurations: System: Ubuntu 20.04 Python version: 3.8.10 Nvidia driver version: 525.116.04 CUDA version: 11.3 GPU: Nvidia RTX A4000
When I type in "sudo make" to compile this repository, errors occur as follows:
yyy@yyy-ThinkStation-P520c:/home/Software/cufinufft$ sudo make [sudo] yyy 的密码： nvcc --device-c -c -std=c++14 -ccbin=g++ -O3 -arch=sm_70 -gencode=arch=compute_35,code=sm_35 -gencode=arch=compute_50,code=sm_50 -gencode=arch=compute_52,code=sm_52 -gencode=arch=compute_60,code=sm_60 -gencode=arch=compute_61,code=sm_61 -gencode=arch=compute_70,code=sm_70 -gencode=arch=compute_75,code=sm_75 -gencode=arch=compute_75,code=compute_75 -Wno-deprecated-gpu-targets --default-stream per-thread -Xcompiler "-fPIC -O3 -funroll-loops -march=native -std=c++14" -I/usr/local/cuda/include -Icontrib/cuda_samples -I include src/precision_independent.cu -o src/precision_independent.o /bin/sh: 1: nvcc: not found **make: * [Makefile:114：src/precision_independent.o] 错误 127
The lines 113 and 114 of the Makefile is in the following: %.o: %.cu $(HEADERS) $(NVCC) --device-c -c $(NVCCFLAGS) $(INC) $< -o $@
I do not know how to solve this problem. Could you give me a hand?Thanks very much!
