DPC++ compilation error in the DPCT migrated LULESH code on Intel DevCloud

I'm working on migration CUDA version of LULESH application (https://github.com/LLNL/LULESH/tree/2.0.2-dev/cuda) to DPC++. I was able to successfully convert the CUDA version to DPC++ using DPCT tool. However, while compiling the DPC++ version of the code, I am getting the following compilation error: error: no matching constructor for initialization of 'std::vec tor<double>

 

./vector.h:24:43: error: no matching constructor for initialization of 'std::vec tor<double>'

I'm not sure if this is an issue with a version of standard library implementation in the devcloud. I'm attaching the makefile and corresponding converted dpc++ files for reference.

Hi,


Thanks for reaching out to us.

Please share the commands you followed for migrating your cuda code to dpc++. Also, the makefile is not there in the attached documents.

Do send us complete error logs and the version of basekit you are using to migrate the mentioned project.


Warm Regards,

Abhishek

Hello Abhishek,

I have used the following commands to convert the CUDA code to DPC++ version.

intercept-build make

dpct -p compile_commands.json --in-root=./ *.cu
dpct --cuda-include-path=/home/uXXXXX/tkit/include -p compile_commands.json --in-root=./ *.cu

 Once the source code is converted into DPC++ format. I have commented out CUDA error-handling API calls which are not converted by DPCT tool.  Now I'm left with one error after compilation, as mentioned below:

$ make all
dpcpp -O2 -g -std=c++17 -c lulesh.dp.cpp -o lulesh.o

Hi,

 

We tried the same application and it got migrated successfully. But at the time of compiling migrated codes, we got the same errors as you have sent to us. 

We are looking into this issue and will get back to you as soon we get any updates on this issue. Please post back to us if you have any other issues.

Warm Regards,

Abhishek

Hi,


We tried your application and we feel that it's a bug, so we are forwarding this issue to the concerned team. Thanks for reporting the issue.


Warm Regards,

Abhishek

I had a discussion with the Developer. He said: "If you want to inherit the constructors from std::vector, you have to use a 'using' statement." Link: https://en.cppreference.com/w/cpp/language/using_declaration#Inheriting_constructors
