c2s - fatal error: 'cmath' file not found

[CABELO]

When I went to run the c2s command on SUSE I got this error below:

$ c2s vectorAdd.cu

Hi,

Thanks for posting in Intel Communities.

Could you please confirm whether the code you are trying (vecadd.cu)is the same as the sample code attached in the zip file?

We have the tried attached code with Intel DPC++ Compatibility Tool and it worked as expected.

Please refer to the below screenshot for more details:

Please let us know if you have any issues with Intel DPCT.

Regarding c2s we suggest you to raise your issue in the below GitHub page.

Hi Noorjahan.

I tested the example you sent above.(vecadd.cu) with c2s from github. I got this error below:

Hi,

This forum supports migrating Cuda to sycl using Intel DPC++ Compatibility Tool.

We request you to raise a issue on below Github page as you are unable to port simple program with c2s.

https://github.com/oneapi-src/SYCLomatic/issues

Could you please let us know if you have any issues related to Intel DPCT Tool? If not, can we go ahead and close this case?

Thanks & Regards,

Noorjahan.

Hi Noorjahan:

I tested it with dpct and the error was the same. See the evidence below:

$ dpct --in-root=. --cuda-include-path=/usr/local/cuda-11.8/include/ --enable-ctad --out-root=dpct_out vectorAdd.cu

Hi,

Could you please provide the exact version of OS you are using to migrate your code?

Also please let us know the GCC version you are using.

Also please check whether you meet the system requirements of Intel DPC++ Compatibility Tool.

Hi Noorjahan

I was using SUSE Enterprise 15-SP3, when I upgraded to 15-SP4 everything worked. Thank you for your support and attention.

Everything is ok now.
