从头文件链接到的头文件未找到。 [英] Header files linked to from header file not found.
问题描述
我有Nvidia的的OpenCL / Cuda的框架问题,但我认为这是一个 GCC
连接问题。
I have a problem with Nvidia's OpenCl/Cuda framework, but I think it is a gcc
linking issue.
的 opencl_hello_world.c
例如文件使用下面的头文件:
The opencl_hello_world.c
example file uses following header file:
#include "../OpenCL/common/inc/CL/opencl.h"
与 opencl.h
使用这些头文件:
#include <../OpenCL/common/inc/CL/cl.h>
#include <../OpenCL/common/inc/CL/cl_gl.h>
#include <../OpenCL/common/inc/CL/cl_gl_ext.h>
#include <../OpenCL/common/inc/CL/cl_ext.h>
因此,所有的头文件都在同一个文件夹中。
So all the header files are in the same folder.
当我再与 GCC编译-std opencl_hello_world.c C99 = -lOpenCL
我收到以下错误消息:
When I then compile with gcc opencl_hello_world.c -std=c99 -lOpenCL
I get following error messages:
error: ../OpenCL/common/inc/CL/cl.h: No such file or directory
error: ../OpenCL/common/inc/CL/cl_gl.h: No such file or directory
...
虽然 cl.h
和其他头文件位于此文件夹中。
Even though cl.h
and the other header files are located in this folder.
搜索虽如此,我再变,包括在 opencl.h
到
Having searched SO, I then changed the includes in the opencl.h
to
#include "cl.h"
#include "cl_gl.h"
我如何在这里读到: GCC不能找到一个包含的头。
但与框架头文件乱搞似乎不是要走的路?什么是处理这个问题的正确方法?
But messing around with the frameworks header files does not seem like the way to go? What would be the proper way to handle this problem?
推荐答案
您要同时使用的#include形式的#include&LT;>,它不会在相同的路径进行搜索。 是本地的项目,并指定gcc的-I命令行,&LT;>是-I指定GCC的系统路径
You're using both #include "" form and #include <>, which don't search in the same paths. "" is local to your project, and the -i command line specified to gcc, <> is the 'system' path specified by -I to gcc.
您可能需要设定-ipath包含路径/到/包括GCC的命令行。
You probably need to set the include path with -Ipath/to/includes in gcc's command line.
