将 Glade 与 CUDA 编译器 (Nvidia Eclipse Nsight) 结合使用 -> 哪个 NVCC 链接器设置?
Using Glade with CUDA compiler (Nvidia Eclipse Nsight) -> which NVCC linker settings?
我正在开始一个涉及 CUDA 的新项目,我想使用 Glade (v3) 作为 GUI。
我正在尝试在一个基本的 CUDA 模板项目中实现一个 Glade 项目,这是我目前的代码:
#include <iostream>
#include <numeric>
#include <stdlib.h>
#include <gtk/gtk.h>
static void CheckCudaErrorAux (const char *, unsigned, const char *, cudaError_t);
#define CUDA_CHECK_RETURN(value) CheckCudaErrorAux(__FILE__,__LINE__, #value, value)
/**
* CUDA kernel that computes reciprocal values for a given vector
*/
__global__ void reciprocalKernel(float *data, unsigned vectorSize) {
unsigned idx = blockIdx.x*blockDim.x+threadIdx.x;
if (idx < vectorSize)
data[idx] = 1.0/data[idx];
}
/**
* Host function that copies the data and launches the work on GPU
*/
float *gpuReciprocal(float *data, unsigned size)
{
float *rc = new float[size];
float *gpuData;
CUDA_CHECK_RETURN(cudaMalloc((void **)&gpuData, sizeof(float)*size));
CUDA_CHECK_RETURN(cudaMemcpy(gpuData, data, sizeof(float)*size, cudaMemcpyHostToDevice));
static const int BLOCK_SIZE = 256;
const int blockCount = (size+BLOCK_SIZE-1)/BLOCK_SIZE;
reciprocalKernel<<<blockCount, BLOCK_SIZE>>> (gpuData, size);
CUDA_CHECK_RETURN(cudaMemcpy(rc, gpuData, sizeof(float)*size, cudaMemcpyDeviceToHost));
CUDA_CHECK_RETURN(cudaFree(gpuData));
return rc;
}
float *cpuReciprocal(float *data, unsigned size)
{
float *rc = new float[size];
for (unsigned cnt = 0; cnt < size; ++cnt) rc[cnt] = 1.0/data[cnt];
return rc;
}
void initialize(float *data, unsigned size)
{
for (unsigned i = 0; i < size; ++i)
data[i] = .5*(i+1);
}
int main(int argc, char *argv[])
{
static const int WORK_SIZE = 65530;
float *data = new float[WORK_SIZE];
initialize (data, WORK_SIZE);
GtkBuilder *builder;
GtkWidget *window;
gtk_init(&argc, &argv);
builder = gtk_builder_new();
gtk_builder_add_from_file (builder, "GladeTest01.glade", NULL);
window = GTK_WIDGET(gtk_builder_get_object(builder, "applicationwindow1"));
gtk_builder_connect_signals(builder, NULL);
g_object_unref(builder);
gtk_widget_show(window);
gtk_main();
/*
float *recCpu = cpuReciprocal(data, WORK_SIZE);
float *recGpu = gpuReciprocal(data, WORK_SIZE);
float cpuSum = std::accumulate (recCpu, recCpu+WORK_SIZE, 0.0);
float gpuSum = std::accumulate (recGpu, recGpu+WORK_SIZE, 0.0);
/* Verify the results *//*
std::cout<<"gpuSum = "<<gpuSum<< " cpuSum = " <<cpuSum<<std::endl;
/* Free memory *//*
delete[] data;
delete[] recCpu;
delete[] recGpu;
*/
return 0;
}
// called when window is closed
void on_QuitApp()
{
gtk_main_quit();
}
在编译时,我无法理解为什么会出现这些错误:

make: *** [GladeTest] Error 1
因为一切似乎都在 gtk.h 中定义,所有其他内容都包含在其中...
我在这里错过了什么?
有人能给我一些指示或告诉我我做错了什么吗?

这是使用的编译命令:

如果我正确理解答案,所有 -I 选项都应该在 nvcc 链接器调用中而不是在 nvcc 编译器命令中?

这是我尝试过的众多变体之一。每次都有相同的结果:

重要的是要认识到您所看到的错误来源是链接,而不是编译,原因是您没有链接所需的 GTK 库。
我能够根据您在 Ubuntu 系统上针对 GTK2 发布的代码(稍作修改)生成可执行文件,如下所示:

这里我使用 pkg-config
获取必要的编译器标志和链接器依赖项,并将它们直接传递给 nvcc
。如果您无法访问 pkg-config
,您可以手动构建它们。重要的一点是将库依赖项 放在您自己的代码之后 。 GNU 链接器从左到右读取依赖项,如果您在 before 依赖它的代码中指定一个库,链接器将丢弃该库并导致链接错误。
编辑:在 Nsight Eclipse 版本中执行此操作
使用 $(shell pkg-config ...)
在编译器和链接器阶段的项目属性中添加 pkg-config
命令:
使用您的代码构建项目会给出此构建日志:

如果我正确理解答案,所有 -I 选项都应该在 nvcc 链接器调用中而不是在 nvcc 编译器命令中?
编辑 2: 这是我尝试过的众多变体之一。每次都有相同的结果:

重要的是要认识到您所看到的错误来源是链接,而不是编译,原因是您没有链接所需的 GTK 库。
我能够根据您在 Ubuntu 系统上针对 GTK2 发布的代码(稍作修改)生成可执行文件,如下所示:

这里我使用 pkg-config
获取必要的编译器标志和链接器依赖项,并将它们直接传递给 nvcc
。如果您无法访问 pkg-config
,您可以手动构建它们。重要的一点是将库依赖项 放在您自己的代码之后 。 GNU 链接器从左到右读取依赖项,如果您在 before 依赖它的代码中指定一个库,链接器将丢弃该库并导致链接错误。
编辑:在 Nsight Eclipse 版本中执行此操作
使用 $(shell pkg-config ...)
在编译器和链接器阶段的项目属性中添加 pkg-config
命令:
使用您的代码构建项目会给出此构建日志:
