Hi!

Thanks for the releasing the repo.

When installing from the source I encountered the following error:

OpenDBA$ make DOUBLE_UNSUPPORTED=1

make: *** [Makefile:36: openDBA.o] Error 1

I am using CUDA11.0 and CentOS 7.
Thanks in advance for your help!

Hi,

This looks like a very specific compiler issue, can you tell me the version of the C++ compiler and you are using? It looks a bit like a compiler macro processing issue like this. Does it compile if you omit -DDOUBLE_UNSUPPORTED=1?

Cheers,

Paul

[zaemyung]

I tried compiling with both devtoolset-7 and -9, with and without the DDOUBLE_UNSUPPORTED, and the error persists.
Could you tell me your dev environment for the compilation?

[nodrogluap]

Hi, can you try again with a new pull? I just committed a version where 0.0 is now explicitly listed as 0.0f with a double conversion in dba.hpp. This may fix whatever compiler weirdness is causing 0.0 to be interpreted as a const char * as revealed in the error messages you list. It won't necessarily fix the functional_hash.h issues, but it's a start.

[zaemyung]

Thanks for looking into this.
With the new pull, I get the following output, with/without the DDOUBLE_UNSUPPORTED:

After some googling, I think the error is due to a bug in glibc for CentOS 7.

• https://stackoverflow.com/questions/66090553/unable-to-build-opencv-with-cuda-on-rhel-7
• https://gitlab.com/nvidia/container-images/cuda/-/issues/109#note_503061879

I will try this patch and let you know!

Indeed, the problem was due to the bug in glibc library, and applying the patch resolved the issue (ref.https://access.redhat.com/errata/RHBA-2021:0439).
Thanks for your help!
