cuFFT static linking failed

Question

I tried to link cuFFT statically.

nvcc -ccbin g++ -dc -O3 -arch=sm_35  -c fftStat.cu fftStat.o;
nvcc -ccbin g++ -dlink -arch=sm_35 fftStat.o -o link.o;
g++ main.cc link.o fftStat.o -lcudart -lcudadevrt -lcufft_static   -lculibos -ldl -pthread -lrt -L/usr/local/cuda-10.2/lib64 -o run

It gave me the following errors ( not showing all the errors)

Dynamic linking works:

g++ main.cc link.o fftStat.o -lcudart -lcudadevrt -lcufft -L/usr/local/cuda-10.2/lib64 -o run

I followed this guide https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#code-changes-for-separate-compilation and this guide https://docs.nvidia.com/cuda/cufft/index.html#static-library but apparently something is missing.

Some of the things you are attempting to accomplish at final link need to be accomplished at device link (your 2nd step). The following seems to work for me:

$ cat fftStat.cu
#include <cufft.h>

void test(){

  cufftHandle h;
  cufftCreate(&h);
}

$ cat main.cpp
void test();

int main(){

  test();
}

$ nvcc -ccbin g++ -dc -O3 -arch=sm_35  -c fftStat.cu fftStat.o
$ nvcc -ccbin g++ -dlink -arch=sm_35 fftStat.o -o link.o -lcufft_static -lcudadevrt
$ g++ main.cpp link.o fftStat.o -L/usr/local/cuda-10.2/lib64   -lcufft_static -lcudart -lcudadevrt -lculibos -ldl -pthread -lrt  -o run

Note that I've also rearranged some link orders to account for link dependencies. This may or may not matter depending on your exact version of g++. Some of the needs here (e.g. -lcudadevrt at the device-link step) may be a function of your actual code, which you haven't shown. For the above code, that item is not actually necessary.

Thank you! I actually did not know that the device link stage ( 2nd stage in my example) requires additional links. In my defense I just followed this example: `nvcc --gpu-architecture=sm_50 --device-c a.cu b.cu ; nvcc --gpu-architecture=sm_50 --device-link a.o b.o --output-file link.o; nvcc --lib --output-file libgpu.a a.o b.o link.o g++ host.o --library=gpu --library-path= \ --library=cudadevrt --library=cudart` which is showed here https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#code-changes-for-separate-compilation — user3786219, Aug 06 '20 at 18:23
