问题

我尝试执行官方CUDA NVRTC指南中的saxpy示例,链接在这个页面

在终端上使用g++编译器并按照构建说明进行操作,它可以正常工作:

g++ saxpy.cpp -o saxpy -I $CUDA_PATH/include -L $CUDA_PATH/lib64 -lnvrtc -lcuda -Wl,-rpath,$CUDA_PATH/lib64

现在我正在尝试使用cgo工具在Go语言中执行它。我将主函数命名为"my_function",并尝试使用C.my_function进行调用。

这是我的cgo指令:

//路径
#cgo LDFLAGS: -L/usr/local/cuda-7.0/lib64 -L/usr/local/cuda-7.0/lib -lcuda -lnvrtc
#cgo CPPFLAGS: -I/usr/local/cuda-7.0/include/ -I/usr/include/c++/4.8

//文件
#include "saxpy_header.h"
#include <nvrtc.h>
#include "iostream"
#include <cuda.h>

但是我收到了以下错误消息:

/usr/include/c++/4.8/iostream:38:28: fatal error: bits/c++config.h: No such file or directory
#include <bits/c++config.h>

所以我尝试了这个:

#include "/usr/include/x86_64-linux-gnu/c++/4.9/bits/c++config.h"

现在我收到了这个新的错误消息:

/usr/include/x86_64-linux-gnu/c++/4.9/bits/c++config.h:430:29: fatal error: bits/os_defines.h: No such file or directory
#include <bits/os_defines.h>

在添加#include "/usr/include/x86_64-linux-gnu/c++/4.9/bits/os_defines.h"之后,我收到了相同的错误...

我该如何解决这个问题?

英文:

I tried to execute the saxpy exemple from the official cuda nvrtc guide in this page

It works fine with the g++ compiler on terminal and following the build instructions:

g++ saxpy.cpp -o saxpy -I $CUDA_PATH/include -L $CUDA_PATH/lib64 -lnvrtc -lcuda -Wl,-rpath,$CUDA_PATH/lib64

Now I'm trying to execute it in go language with the cgo tool.
I named main function in "my_function" and I'm trying to call it with C.my_function.

this is my cgo directives:

//PATH
#cgo LDFLAGS: -L/usr/local/cuda-7.0/lib64 -L/usr/local/cuda-7.0/lib -lcuda -lnvrtc
#cgo CPPFLAGS: -I/usr/local/cuda-7.0/include/ -I/usr/include/c++/4.8

//FILE
#include &quot;saxpy_header.h&quot;
#include &lt;nvrtc.h&gt;
#include &quot;iostream&quot;
#include &lt;cuda.h&gt;

But I get this error message:

/usr/include/c++/4.8/iostream:38:28: fatal error: bits/c++config.h: No such file or directory
#include &lt;bits/c++config.h&gt;

So I tried this:

#include &quot;/usr/include/x86_64-linux-gnu/c++/4.9/bits/c++config.h&quot;

And now I get this new error message:

/usr/include/x86_64-linux-gnu/c++/4.9/bits/c++config.h:430:29: fatal error: bits/os_defines.h: No such file or directory
#include &lt;bits/os_defines.h&gt;

After adding #include &quot;/usr/include/x86_64-linux-gnu/c++/4.9/bits/os_defines.h&quot; I get the same error...

How can i solve this problem?

根据你提供的内容,我给出以下翻译:

只是一个猜测,因为我对go / cgo一无所知...

看起来你在g++编译器的4.8版本和4.9版本之间搞混了。

我建议尝试相应地更改cgo CPPFLAGS行,如下所示:

#cgo CPPFLAGS: -I/usr/local/cuda-7.0/include/ -I/usr/include/c++/4.9

但再次强调,这只是猜测...

英文:

Just a wild guess here since I know nothing of go / cgo...

It looks like you have amix-up between version 4.8 and 4.9 of the g++ complier.

I would try to change the cgo CPPFLAGS line accordingly, to this:

#cgo CPPFLAGS: -I/usr/local/cuda-7.0/include/ -I/usr/include/c++/4.9

But again, just guessing...
