我试图静态地链接cuFFT。
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它给了我以下错误(没有显示所有的错误)

g++ main.cc link.o fftStat.o -lcudart -lcudadevrt -lcufft -L/usr/local/cuda-10.2/lib64 -o run我遵循了这个指南https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#code-changes-for-separate-compilation和这个向导https://docs.nvidia.com/cuda/cufft/index.html#static-library,但是显然缺少一些东西。

有些事情,你想要完成的最后环节,需要完成在设备链接(你的第二步)。以下几点似乎适用于我:
$ 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请注意,我还重新安排了一些链接顺序,以说明链接依赖关系。这可能重要,也可能不重要,取决于您的确切版本的g++。这里的一些需求(例如,设备链接步骤中的-lcudadevrt )可能是实际代码的一个函数,但您还没有显示出来。对于上面的代码,该项实际上并不是必需的。
