我想在另一个仓库中外部使用 FAISS C++ GPU。因此，我创建了一个 hello.cpp 并尝试在不进入 faiss 目录的情况下对其进行编译。在 faiss 目录中，编译对我来说似乎很好。

  • hello.cpp（C++ Faiss GPU）：
#include <cmath>
#include <cstdio>
#include <cstdlib>
#include <random>
#include <sys/time.h>
#include <faiss/gpu/GpuIndexIVFPQ.h>
#include <faiss/gpu/StandardGpuResources.h>
#include <faiss/gpu/GpuCloner.h>
#include <faiss/utils/random.h> 
#include <fstream> 
#include <faiss/gpu/utils/DeviceUtils.h>
#include <faiss/gpu/utils/Timer.h>
#include <string>
#include <iostream>
#include <faiss/gpu/GpuAutoTune.h>
#include <faiss/index_io.h>
using namespace std;

double elapsed() {
    struct timeval tv;
    gettimeofday(&tv, NULL);
    return tv.tv_sec + tv.tv_usec * 1e-6;
}
int main() {
    double t0 = elapsed();
    printf("[%.3f s] Hello World! :))\n",
           elapsed() - t0);
    faiss::gpu::StandardGpuResources res; // Without this line, nvcc works.

    return 0;
}

命令：

/usr/local/cuda/bin/nvcc /home/hossamamer/hello.cpp -lcublas -lfaiss -o myCublasApp

输出：

有什么帮助吗？我也可以使用 make 命令执行此操作吗？命令是什么？
