CUDA文件编译错误

EmuDebug编译通过，而在Release下出现的编译错误

 

 

tmpxft_000011f8_00000000-3.gpu
tmpxft_000011f8_00000000-7.gpu
### Assertion failure at line 907 of ../../be/cg/NVISA/cgemit_targ.cxx:
### Compiler Error in file C:/DOCUME~1/CDW/LOCALS~1/Temp/tmpxft_000011f8_00000000-8.i during Assembly phase:
### NYI initv kind 1
nvopencc ERROR: d:/CUDA/bin/../open64/lib//be.exe returned non-zero status 1

错误原因：

typedef  struct  STU_t 
... {
    int a;
    struct STU_t *p;
}  STU;

__device__ STU_t stu1[ 2 ]  =  
... {
    ...{1, NULL},
    //{2, &stu1[0]},//error 可能无法取得地址
    ...{2, NULL},//ok,需要以后进行初始化
} ;

### Assertion failure at line 907 of ../../be/cg/NVISA/cgemit_targ.cxx:
### Compiler Error in file C:/DOCUME~1/CDW/LOCALS~1/Temp/tmpxft_00000e18_00000000-8.i during Assembly phase:
### NYI initv kind 1
nvopencc ERROR: d:/CUDA/bin/../open64/lib//be.exe returned non-zero status 1

错误原因：

1. 可能是在device函数中引用或访问了属于Host memory的内存地址
2. 结构体内仍包含结构体指针，CUDA无法解析，如下代码；

typedef  struct  teacher_t
... {
    int age;
    char *name;
    state_t *p_states;
} Teacher;

__global__  void  test3(teacher_t  * teacher)
... {
    teacher->name = "davidchan";  //ok
    teacher->p_states->qeval = 123;//error 无法解析地址
}
