compilation error

[KunalTon]

When I try to complile the code, I get the following error:

I kindly ask to excuse me for the very late answer.
What compiler and what version of compiler do you use? And the same for CUDA sdk.

[KunalTon]

I am using cuda-11.2
and gcc version 4.8.5 20150623 .

I have another question, I want to use VM2D for a fluid-structure interaction (FSI) problem with 2 degrees of freedom. I want vertical motion as well as rotational motion. Can VM2D be used for 2 Degree of freedom FSI problem?

[dingzhw]

I have run into the same problem, if you've got a solution, please let me know, thanks a lot!

[zghydxsyk]

I also met this problem

[DonBetur]

Is there a way to compile VM2D without CUDA? Got same problem on Linux, but I don't got a NVIDIA CUDA GPU.

[vortexmethods]

Yes, sure!
I will update current code in a few days (minor bugs, that have been found) and write here how to compile without CUDA.

[KunalTon]

has this issue been resolved?

[MustafaAlperenMadenci]

Same error happened to me :/ using macos

Hi, I get the same error if I compile commenting -DUSE-CUDA in CMakefile.lst, while if I try to compile by using cuda, compilation fails at bvh.cuh with the following error:
intersection/lbvh/bvh.cuh:22:10: fatal error: cuda/functional: no such file or directory
Do you have any suggestion? I am working on Debian:
-The C compiler identification is GNU 12.2.0 -The CXX compiler identification is GNU 12.2.0 -The CUDA compiler identification is NVIDIA 11.8.89

UPDATE:
I update my cuda toolkit to the latest version and the previous error has been resolved, but now I get a new error at 88% of the process in the file Wake2D.cpp:
VM2D/src/VM2D/Wake2D/Wake2D.cpp:51:10: fatal error: knnCPU-new.h: no such file or directory
