Issues compiling ShivaniK_Intel's hello_world.cpp.

[Zippy_Pinhead]

I am trying to build the hello_world.cpp ShivaniK_Intel suggested in this problem solution: community.intel.com/t5/Intel-oneAPI-Base-Toolkit/DPC-setup-question/m-p/1317438#M1823

I got past the fact that installing the intel-basekit did not include intel-oneapi-compiler-dpcpp-cpp-common as a prerequisite by installing it by hand. Now I am dealing with this issue:

toddb@zippy $ dpcpp hello_world.cpp
In file included from hello_world.cpp:1:

13 errors generated.

To make this more complete, here is the program I am trying to compile:

#include <CL/sycl.hpp>
#include <iostream>
using namespace sycl;
const std::string secret {
"Ifmmp-!xpsme\"\012J(n!tpssz-!Ebwf/!"
"J(n!bgsbje!J!dbo(u!ep!uibu/!.!IBM\01"};
const auto sz = secret.size();
int main() {
queue Q;
char*result = malloc_shared<char>(sz, Q);
std::memcpy(result,secret.data(),sz);
Q.parallel_for(sz,[=](auto&i) {
result[i] -= 1;
}).wait();
std::cout << result << "\n";
return 0;
}

I do not know why ShivaniK_Intel chose such an unreadable example, but that is one of life's great mysteries. (smiley face)

Any help in getting this hello_world.cpp to compile is appreciated.

This is a fresh install of intel-basekit with the additional install mentioned above to fix the problem with the basekit prerequisites.

The install is on Ubuntu Linux Kernel version 18.04.6.

Thank you,

Zippy

Hi,

Thanks for reaching out to us.

Could you please confirm whether you are able to compile and execute a sample simple-add program?

>>>I do not know why ShivaniK_Intel chose such an unreadable example, but that is one of life's great mysteries. (smiley face)

As the user from your referred thread is working on hello_world.cpp program from the Data-Parallel C++ book (https://link.springer.com/content/pdf/10.1007%2F978-1-4842-5574-2.pdf), so we have chosen the same source code.

Could you also confirm the version of dpcpp compiler you have been using?

Please refer to the attachment for the sample simple-add program.

Thanks & Regards

Shivani

Above, you can see the same 13 errors when compiling simple_add.cpp.

Here is my version of dpcpp:

toddb@zippy $ dpcpp --version
Intel(R) oneAPI DPC++ Compiler 2021.1 (2020.8.0.0827)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /opt/intel/compilers_and_libraries_2020.4.304/linux/bin

Please let me know if there is anything else.

p.s. Let me remind anyone reading that when I did the initial install, the CL (sycl) includes were not installed because of a broken dependency in intel-basekit. Here is what I have for intel-basekit and the item which failed to install properly:

toddb@zippy $ s apt install intel-basekit

Hi,

Could you please follow the steps in the below link and try re-installing the latest version of Intel oneAPI toolkits.

https://software.intel.com/content/www/us/en/develop/documentation/installation-guide-for-intel-oneapi-toolkits-linux/top/installation/install-using-package-managers/apt.html#apt

To check whether the installation is successful, first do run setvars.sh script as follows:

source <install-dir>/setvars.sh

Now, try checking any compiler version.

dpcpp --verion

Expected Output:

After successful installation, try running the hello_world.cpp program.

Compilation command: dpcpp hello_world.cpp -o hello_world

Execution command:./hello_world

Expected output:

Thanks & Regards

Shivani,

This worked! Thank you very much. I thought I had already "cycled the power" on the install once, but perhaps I missed something.

For anyone else trying this fix, I added this to your instructions:

After doing the autoremove, I checked to see if any components were still installed:

toddb@zippy $ s apt list --installed | grep intel-oneapi

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

intel-oneapi-common-licensing-2021.4.0/all,all,all,now 2021.4.0-327 all [installed,automatic]

intel-oneapi-runtime-dpcpp-cpp-common/all,all,all,now 2021.4.0-3561 all [installed]

I then was able to uninstall the rest by doing an "autoremove" on the licensing package, to which everything else appeared to be a dependent. You can see now there is nothing installed:

toddb@zippy $ s apt list --installed | grep intel-oneapi

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

The output from the compiler version check and hello_world.cpp is the same as what you posted. Thank you once again for taking the time to help.

I will now install the debugger and a couple of other things and move forward!

Hi,

Thanks for accepting our solution. If you need any additional information, please post a new question as this thread will be no longer monitored by Intel.

Thanks & Regards
