Error when linking SofaCuda

[BrunoB81HK]

Hi,

When building SofaCuda, I came across a linking error that I couldn't seem to fix. Do anyone has any idea what causes this?

Using:

• Ubuntu 20.04
• Sofa 22.06
• CUDA build cuda_11.8.r11.8/compiler.31833905_0 (was having this error with 11.7 too)
• CMake variable:
  SOFACUDA_CUBLAS:BOOL=ON
SOFACUDA_CUDPP:BOOL=OFF
SOFACUDA_DOUBLE:BOOL=ON
SOFACUDA_DOUBLE_PRECISE:BOOL=ON
SOFACUDA_PRECISE:BOOL=ON
SOFACUDA_THRUST:BOOL=ON
SOFACUDA_VERBOSE_PTXAS:BOOL=OFF
CUDA_NVCC_FLAGS:STRING=--ptxas-options=-v;-arch sm_75

Hey @BrunoB81HK ,

have you solved your linking problem?
I really don't see why there should be a link failure. But I checked on master, which I am able to compile, and the CI platform as well. Have your tried updating your SOFA to the master branch?

[BrunoB81HK]

No, I didn't solve it. I haven't tried to update to master since I don't want to introduce breaking changes to my code. I will try it today.

[hugtalbot]

any update @BrunoB81HK ?

[BrunoB81HK]

Since time is limited, I haven't had time to try it and I don't want to deal with the changes needed by switching to the master branch at the moment. I'll try it when I'll have more time to troubleshoot it.

Perfectly understandable, keep us posted ;)
