DPC++ static lib for another project still compiled by DPC++ compiler

shenuo — Thu, 21 Apr 2022 06:11:13 GMT

Hi,

I have 2 projects, both of them are compiled by DPC++ compiler, the first one contains a kernel function, and is compiled as a static lib(it is correct as when compiled as exe, it can run). the other only has a main function and is compiled as a executable file which link the first one.(both of them use same main function)

However, I got a runtime error when I run the second one. I find this error come from the submit function.

template <typename T> event submit(T CGF _CODELOCPARAM(&CodeLoc)) {
_CODELOCARG(&CodeLoc);

event Event;

.......//other no related code

{
Event = submit_impl(CGF, CodeLoc);
}

return Event;
}

where submit_impl return a runtime error at memory.

My environment is DPC++ 2022 + vs2019 with i7-10610U CPU and UHD 630 graphics.

so, could anyone tell me what I miss?

Hi,

Thank you for posting in Intel Communities.

Could you please share the sample reproducer code, so that we can reproduce the issue from our end?

Thanks & Regards,

Hi,

you can just use the default DPC++ project on visual studio (static lib) to replay the same result.

int main() {

IntArray Iarray1, Iarray2,Iarray3;
initialize_array(Iarray1);
vector_add(Iarray1,Iarray2,Iarray3);
return 0;
}

Hi,

We can run the static library successfully by following the below steps:

1) Open Visual Studio and select the static DPC++ library project.

2) Create a dpcpp project as a static project.

3) Build the static project.

4) Create a new DPC++ project.

5) Create a new sample C++ file and copy the program2.cpp file as attached.

6) Open project properties>>Configuration properties>>VC++ Directories>> Library Directories(add the static library output path)

7) Open project properties>>configuration properties>>Linker>>General>>pass additional options to the device compiler>> (Add the static library output path)

please try using the above steps and let us know if you face any issues.

Thanks & Regards,

Hemanth

Hi，

Thanks, It seems the DPC++ static lib configuration is not same as normal C++ static lib.

now, It works correct!
